Today we are more dependent than ever on technology. It is in how we communicate, in the way we live and currently even in the infrastructure of our homes. As part of this transformation, it is increasingly necessary for talent to dedicate themselves to programming, the language that governs technological and digital ecosystems.

However, dedicating yourself to programming is not necessarily a straight path. As it happens with the job of interpreting, the programmer must know different languages that will help him to register and execute the commands of his creations.

Language? Yes. In programming, there are different types of languages: they are sign systems that allow interaction between humans and computers. Although most of the languages are versatile and serve to achieve almost any objective, today we present you a list of the most common ones and their main use case.

THE PROGRAMMING LANGUAGES MOST USED

1.PYTHON

The first of the programming languages that we will meet in this list was born in 1991. Although today it is the first reference in programming, it took some time for it to gain public attention.

Currently it stands out among the majority for its versatility and its ability to learn, becoming a must have for programmers who want to work in Machine Learning and Data Science.

Not only is it easy to use and it focuses on making it easy to read. It also allows you to assemble all kinds of applications and web pages. It is also an incredible ally for projects that involve a lot of data analysis.

2.JAVA

When it comes to versatility, Java is the star of the party. For many years, it captured the attention of programmers around the world, due to its “object” oriented approach. An approach that also allows it to work without conflicts on any hardware.

During its heyday, it was the standard language for the development of all kinds of smart machinery, such as points of sale, ATMs, smart coffee machines, and even web pages.

 

3.JAVASCRIPT

Those of you from the 90s generation will surely remember the hundreds of free games that many websites used to publish in the early 2000s. These games were mostly created with JavaScript.

This language is used, above all, for web development and interaction between the program and its user. It is usually behind the operation of buttons, online games, animations, and even digital forms.

In addition to being a language that is widely used, it is very versatile and easy to learn xxx porno, making it ideal for beginners.

4. SWIFT

Are you interested in the world of apps? You may have to start by learning this language. After all, it is this one that will allow you to publish on the Apple App Store.

It was created precisely by this company, as a hallmark for its applications. It is very similar to its ancestor, the “Objective-C” language, highlighting clarity among its main characteristics.

 

5. C (AND ALL ITS DERIVATIVES)

The last language on this list was born between 1969 and 1972, thanks to Dennis Ritchie at Bell Laboratories. His idea was to create an evolution of the B language, which would allow it to do more in the implementation of various operating systems.

Over time, and thanks to the versatility of this language, other languages have emerged that are derived from C: C/C++, C# and Objective.

Now that you know the most popular languages, which one would you like to start learning?

ARTIFICIAL INTELLIGENCE IN EVERYDAY LIFE

Posted on by leonardo

ARTIFICIAL INTELLIGENCE IN EVERYDAY LIFE

Although Artificial Intelligence or AI may sound like a very futuristic technology, the truth is that it is already part of our lives, but not only that, it influences much of our decisions and the content we consume. But not only that, it influences a large part of our decisions and the content we consume. Do you want to know more?

It is true that AI is often associated with robots. However, this is not necessarily true. In fact, AI has developed mostly in the form of software. The principle is the combination of algorithms applied to machines that exhibit human-like characteristics.

According to computer experts Stuart Rusell and Peter Norvig, there are different types of AI: those that think like humans (e.g. artificial neural networks), those that act like humans (e.g. robots), systems that think rationally and systems that act rationally.

In general, the most common AI systems are those that “think like humans,” which are in charge of automating decisions, solving problems and, above all, learning. Now, how and why are they in our daily lives?

 

HOW IS AI PRESENT IN OUR DAILY LIVES?

AI is present in practically all our daily activities that involve technology. For example, facial recognition on our smartphone is AI. Likewise, assistants such as Siri or Google’s assistant also rely on this technology to recognise voice, and perform searches and actions. But not only those on the phone tukif, but also those in the home.

According to a study by HP Development Company, in the United States, one in three households uses a smart speaker. Similarly, 81% of them have a voice assistant. These work thanks to what is known as PLN, or natural language processing, and are able to recognise and respond to commands.

HOW IS AI PRESENT IN OUR DAILY LIVES?

In that sense, what is known as the Internet of Things also relies on AI to function. All smart appliances in the home can be connected to each other, thereby automating processes and making life easier.

 

AI ON THE INTERNET AND SOCIAL NETWORKS

Another application of AI that we can see every day is on the internet and social media. When we search for something on Google, and the text predicts what we mean, it is also AI. The predictive search engine uses the information it knows about you and users who look like you (taking into account age, location, likes, etc.) and guesses what you want to say.

It’s a similar idea to what online shops, such as Amazon, use to collect your information, shopping habits and more to personalise your experience. Speaking of personalisation, social networks also use similar programmes to select content that “looks” like you, content that interests you, and of course, advertising. The idea is to create an experience tailored to you. By the way, this is also done by streaming and music platforms, they get to know your taste to suggest the songs you like the most (although sometimes they fail).

AI ON THE INTERNET AND SOCIAL NETWORKS

As we can see, AI is more present in our lives than we imagine. However, beyond these uses, this technology is already present in fields such as art and writing. We still don’t know how far it will go, and whether we will like the result or whether we will soon be in a dystopia… Or are we already in one?

THE FAILURE THAT CAUSED YOUR FAVORITE GAME MECHANICS

Posted on by leonardo

THE FAILURE THAT CAUSED YOUR FAVORITE GAME MECHANICS

Everyone is wrong, regardless of the scale, scope, or implications of the context. However, where some errors are just that, accidents, others have ended up generating revolutionary discoveries. It happens in the kitchen, it happens in art and, of course, it happens in video games.

If you’re not sure about this, just look at titles like Skyrim, where players take advantage of glitches to find new ways to play and have fun, as well as how funny and unusual what we end up seeing on screen can be.

However, the title that brings us together here today goes far beyond that. This game, far from causing laughter or feeding the evil devil of the roguery of its gaming community, created a new way of playing and, subsequently, revolutionized how most similar titles look and play.

Yes sirs. We talk about Quake.

 

QUAKE AND THE STRAFE-JUMPING

Those who are knowledgeable gamers or simply have a lot of time in front of the computer, will surely remember this title fondly. A series of games with numerous installments and versions, which first saw the light of day on June 22, 1996.

A shooting game, like many others. Objectives, quite simple: aim and kill. So what about Quake that was revolutionary in its time? It wasn’t about what the developers delivered to their audience…it was about what their audience did with the game.

It turns out that, by chance or fate, the players began to notice something unusual, but convenient. For some reason, if they moved by jumping, they could gain speed within the map. After the technique became popular, it was baptized as strafe-jumping porno français.

The technique was especially useful, especially at competitive levels, as it allowed the player to not only go faster for free. But, in addition, you exceeded the character’s maximum movement speed. Three factors were involved in this: the release of friction when walking, the diagonal movement of the character, and the manipulation of the game camera.

There is no reason to lie. Those who know about this technique are aware that it was not easy to apply it. However, when you mastered it, you were able to far outmatch your opponents.

So what was the problem here? That this function did not come from the minds of the programmers or the company that launched the title. But of, on the contrary, a programming error. Ops.

 

FROM BUG TO GAMEPLAY

The truth is that, after making a mistake, you have two options. The option that seems most logical is to correct, of course. However, you can also take advantage of it.

When this happened, it took a while for there to be a consensus within Id Software. There were those who were in favor of fixing the bug. Others, a little more irreverent and revolutionary, bet on giving strength to this mechanic.

Let’s remember that, after all, although it was a way to obtain formidable results, this technique was not easy to apply, making it inconsistent in a normal game.

FROM BUG TO GAMEPLAY

Everything changed with the arrival of Quake Live, an installment of the previous title, completely free. In this version of the game, the programmers created a feature where you legitimately increased your speed by moving around by jumping.

Over time, this mechanic made its way out of Quake, and into games using the same engine: Call of Duty and Wolfenstein: Enemy Territory being some of the most popular examples. There were even games that used derivative engines that had to be edited to somewhat limit the benefits of using staff-jumping, as its use unbalanced player conditions.

And so, a simple programming error by some careless developer gave rise to a technique that marked the gameplay for that and future generations.

How the Netron Data Migration Framework Turns Legacy into Relational

Posted on by admin

1. ANALYSIS: An incremental approach to reduce complexity and risk

Working with a cross-functional team of your data modelers, application developers, and business analysts, Netron consultants conduct JAD sessions to accurately identify the source-to-target data relationships that need to be migrated. Netron’s approach organizes the project into manageable portions, focusing on 10 to 20 tables at a time relating to a specific business function—greatly reducing complications and helping you to better manage your project scope. Source and target data structures are mapped and data transformation rules are captured using state transition diagrams. Information in these diagrams provides the specs that are fed into our unique Netron Data Migration Framework to produce the extract, transform, and load programs required to migrate your data.

2. CONSTRUCTION: Rapid development of data migration programs

Netron’s consultants use our proven Netron Data Migration Framework consisting of data components, templates, wizards, and tools that let us quickly develop data migration programs for moving your data from the source database to the target model. The productivity benefits of our framework will prove to be a critical success factor in your data migration. Not only does the Netron Data Migration Framework build data migration programs that correspond to the analysis just completed, the framework, in conjunction with our methodology, makes it easy to do data scrubbing or to correct analysis mistakes. Once unaccounted conditions are identified, it’s just a matter of updating the diagrams, making minor adjustments to the framework, and regenerating the programs.

3. EXECUTION: Turning legacy into relational

The generated migration programs now navigate the input data sets, performing the necessary fan-in, fan-out, data scrubbing and validation operations to produce an ouput file ready for loading into the target RDBMS. Along the way, a complete set of audit logs and error reports is produced automatically, ready for the validation steps, and highlighting any need for a further iteration.

4. VALIDATION & TESTING: Ensuring a complete and accurate migration process

With millions of records spanning the entire source database, Netron consultants take special care with the testing and validation phase of your data migration effort to ensure the programs accurately and completely transfer the data. Tasks include unit testing, examining log and audit files, data scrubbing, system testing, spot checking, and cross validation of the source and targeted databases xnxx.

5. ITERATIVE REFINEMENT: The key to successful data migration

Second and third iterations are a fact of data migration life—nobody gets it right the first time because complex legacy data is difficult to successfully clean and migrate on the first try. Here’s the twofold Netron Frameworks advantage: The programs we create using the Netron Data Migration Framework have built-in exception handling. And they’re designed with rapid iteration in mind. That means any problems associated with the applications are immediately documented into log and audit reports including hidden data exception and data scrubbing requirements, many of which are unknown at the start of the data migration project, as well as invalid assumptions made at the requirements gathering phase. Then the transition rules can be quickly updated and validated, and the programs regenerated and re-executed. Each iteration helps make the subsequent iteration more robust and complete than the previous one until no exceptions are found.

A services-based solution that offers:

• Incremental conversion to reduce project risk
• Business process driven JAD analysis to reduce complexity
• State transition methodology to define data transformation
• Iterative refinement for better data scrubbing
• Rigorous validation and testing
• Flexible data migration framework for rapid program development/migration
• Rules-based program generation
• Innovative analysis tools for finding business rules
• Intuitive development tools for generating better programs faster using new data

Preferred Source and Target Platforms

Source: Netron Data Migration Process can migrate data from MVS (CICS, IMS/DB and batch environments), OS/400, OS/2, Wang VS, and OpenVMS.

Target: Most Unix and all Windows server platforms. If we haven’t mentioned your platform, please contact Netron — our approach’s adaptability means that it can probably be customized to support your needs.

Supported Source and Target Databases

Source: For legacy data, any database that has Cobol access including IMS, VSAM, sequential files, DB2, and Oracle as well as proprietary legacy databases (e.g., Wang DMS or ) that are no longer fully supported by their vendors.

Target: any RDBMS that can load data from text files, or that is supported by ODBC.

Interviews

Interview With Zinetek Records Interview with Zintek Records

Posted on by admin

ZINETIK have just released their next smash hit Believe Me by GHISLANE. Remixing.info was fortunate enough to grab 5 minutes of ZINETIK’s part owner Leda and we asked him the following:

Remixing.info: Congratulations on the song “Believe Me”. I managed to have a listen to it and I really think the artists and tracks that you have at Zinetik Records are improving immensely with each recording.
Zinetik Records: Thanks a lot. We have got great expectations about this song! Besides producing a good track the quality itself of the production is extremely important in order to compete at a global level. For this reason we consider essential to be able to keep at least the quality level of the newest big productions.

Remixing.info: I read in your email that Believe Me is being distributed in Spain by Vale Music. This must be quite an achievement as Vale Music is the distributor for some big names like DJ Bobo, ATB, Voodoo and Serano. What other territories to you see Believe Me heading into???
Zinetik Records: We always try to set up collaborations with those labels that we know have got more chances to reach a large public audience, without leaving apart the quality and reliability of the productions themselves. Believe Me is a huge success here in Spain and after waiting for this result, we’ve just started moving it abroad. The first step for us is always Europe, because of is proximity and similarity, we are really having a good response so far. We’ve been just offered the chance to set a collaboration with ToCo International (thanks to the essential mediation of Subsonic Records in the person of Dennis Jones) to license it in the other continents…this can be HUGE!!!

Remixing.info: Zinetik Records has only been in operation for less than 3 years, what to you attribute to the success of the label???
Zinetik Records: We pay a great attention in the selection of each our productions that we release, dedicating to every single, all the time it needs to be at its best. Every member of the staff has a pretty long experience in the music field, since before the ZINETIK project started.

Remixing.info: Zinetik Records produces a radio show that is aired on a number of radio stations in Spain. Do you think this helps in producing better music?
Zinetik Records: Yes, it does without any doubts. It allows us to keep always up to date and to keep in contact with people. They are the ones that make a track successful or not, so that knowing what people like and what they ask for are essential in the music world.

Remixing.info: Now if someone is not a DJ or radio show producer how would you suggest that they break into the dance music scene???
Zinetik Records: The most important thing is to have good ideas and pay a great attention to detail. The rest comes along with it, step by step. At a first stage it’s really important to be patient and working hard till you can get a very good first track ready to release.

Remixing.info: The visitors here at remixing.info always like to know about what setups and software that remixers and producers are using. What hardware do you use??? (Eg. audio cards. Pre amps etc). Also what software and plug ins????
Zinetik Records: We use Apple Macintosh with hardware Protools HD2 as support. As a sequencer Logic Audio 5 and for the Audio the software Protools. We don’t use a mixing set, we mix everything with the computer.

Remixing.info: If someone wanted to start their own record label what would you suggest they do???
Zinetik Records: You have to keep well in mind what is your objective and what kind of production you want to release…and the most important thing is to be brave!!!

Remixing.info: What tips would you give an up and coming remixers/producer?
Zinetik Records: Never lose heart, even if the music world is pretty difficult and really selective. The competence as well is hard but it can give you lots of satisfaction….if working in the music field is your main aim and your dream with good productions and consistency, nothing is impossible.

Remixing.info: The visitors of remixing info would like you to part with some of your hard earned knowledge do you feel you could contribute to the remixing.info site in some way???
Zinetik Records: Let’s see…having a good sound library is really important. I’m always sampling other productions, finding new sounds and new ideas and then obviously I modify them with my own style.

Remixing.info: I wish you all the best with “Believe Me”. The videos porno is great and is heading for big things.
Zinetik Records: Thanks a lot for your interest in our production and in particularly in Believe Me…I hope that the visitors of remixing.info can take any advantage of what I wrote.

Just a quick footnote Subsonic Records and Zinetik Records could be joining forces for some new releases. This is great news as I am signed to Subsonic Records and will have the chance to work with the likes of Leda – DJ Scott-e.

Business Rule Identification and Extraction through Netron HotRod

Posted on by admin

How do you migrate from a legacy COBOL system to a modern architecture and ensure that your existing business functionality will still work?

For years you have relied on COBOL as your application development language –– and for batch processing huge amounts of data, it’s hard to beat. But now, your customers are demanding better access to their accounts; your operational units need real-time updates to their data; your supply channel partners insist on closer integration with their systems –– and it seems that just about everything needs integration with the Web.

While COBOL is still efficient at data processing, the language has become much less strategic to the future, because it has lagged in its support for the Internet, layered application architectures, distributed systems and code reuse. By comparison, modern language environments offer ready-to-use class libraries and application objects for Internet, data and Web Service access.

For these and other strategic reasons you have decided it’s time to convert your system to a modern development and deployment platform that will serve your business for the next decade. But can you afford to re-analyze, rebuild and rewrite everything from scratch? Converting to an object-oriented paradigm will require you to morph your business rules into a new class-based object architecture. The challenge in the conversion is getting the correct design requirements. The best definition of the existing requirements is in the current system, and you need to find them quickly. The most compelling reason to reuse your existing business logic is to accelerate the time to market for the replacement system. The next most compelling reason is to reduce risk –– by ensuring your requirements are complete.

The fact that your current system contains millions of lines of COBOL code compounds the problem. The presence of cloned logic further complicates the matter. You need something that can:

• quickly identify business rules in large COBOL systems
• associate the rules with the related data;
• isolate this information into a component design with an interface;
• identify and help eliminate redundancies in the rules
• provide a means to document the rule and extract it from the old system
Netron HotRod™ is the most advanced solution for identifying business logic, isolating and documenting the code that supports the business functionality, and wrapping it in an interface that can be extracted and used to create the business objects in the new architecture.

Our two most important tools enable a fast, robust migration of your system’s business rules and data:
• Netron HotRod™ detects and extracts business logic from Cobol programs quickly and completely, separating the rules from the code. This allows us to quickly evaluate the system and ensure that the migrated system supports the same business operations as the original.
• Netron’s Data Migration Framework helps our consultants manage and accelerate the data migration and data conversion processes to a relational model.
Netron’s System Migration Process incorporates the skills of our consultants, our tools, and strong engineering practices to rejuvenate your system and prepare your business for managing future change.

Using HotRod to separate the business logic from the code, and the Netron Data Migration Framework to remodel your databases, Netron consultants can give you the same system re-architected to take full advantage of the appropriate platform. The Netron Reporting Solution will allow your people to easily examine the data they want in a readable, tabular format from a Word or PDF document, without making the investment of time or money into other reporting technologies.

We can recommend the right class of .NET or J2EE solution for your business and work with you to ensure that the end result suits your needs. Your system will be re-architected to meet usage demands, ranging from lightweight, low-volume solutions for fewer users or heavyweight solutions for enterprise-wide applications. The solution will be scalable so that it can adapt to future needs.

Why testing?

Posted on by admin

Verifying that all requirements are analyzed correctly

Many serious software failures are often the result of wrong, missing or incomplete requirements formulated at the requirement analysis stage. Testing, therefore, verifies that requirements are relevant, coherent, traceable, complete and testable. This is the reason why testing really begins at the outset of a project during the requirements specification phase, prior to the generation of a single line of code.

Verifying that all requirements are implemented correctly

Adequate testing ensures that software operates as expected, providing correct user response and works as per requirement specification. Comprehensive Testing reduces the risk in the marketplace, minimizes system downtime, and increases the confidence in systems for customers and department staff. The key to software testing is trying to find the myriad of failure modes.
Any software application should be examined, tested and analyzed for risk of failure as per the requirement before it is launched into the market and used by the customer.

Identifying defects and ensuring they are addressed before software deployment

It is important to identify the defects at an early stage in the software engineering lifecycle otherwise it could pose a big problem at the time of deployment of the software application. If these defects are identified early and addressed properly it will reduce the cost of development to the extent of 10x as compared to a point when it gets identified after the deployment. The other major factor associated with this problem, not measurable in absolute terms but of more significance to the organization is losing the confidence of the customer and the resulting embarrassment.

Training

We offer courses in refactoring, design patterns, white box and black box testing. We offer customized courses that focus on the customer needs.

Refactoring training
Refactoring requires a thorough understanding of the programming language being used. So, during our course we will uncover some of the language pitfalls developers should try to avoid. We will also look at several possible ways to design a system. Finally we will give an overview of the common refactorings, always relating them back to the design. We have an optional course in exception handling.

Design patterns training
Design patterns will give developers a better insight in how to design software. Our course will focus on the most useful design patterns, starting with the simple ones.

White box testing training
This course will show how to gradually build up confidence in your software product by means of white box testing. We teach how to balance costs of late discovery of bugs against costs of white box testing. Early testing can prevent bugs from growing exponentially during development, but it consumes resources! We explain the various white box techniques (unit testing, integration testing, code inspections, …) and we give some rules for how and when to deploy them. We offer specialized courses concerning white box test tools (white box stress testing, class testing).

Black box testing training
Some of the concepts that will be explained in this course are: Business driven thinking, building test cases, making your test process measurable, practical usage of test requirement hierarchies, test strategies (boundary checking, equivalence partitioning), test automation, test implementation, test attitudes.

Outsourcing
Outsourcing frees your in-house resources to concentrate on your core business, saving you time and resources. Using QualityVision’s staff allows you to keep your engineers and management deployed on your development projects, while ensuring high quality testing for your products.

QualityVision outsources test engineers. We can outsource black box and white box testers.

Black box testers are trained in business driven thinking, test strategies and test tools. They can help making your test process measurable.

White box testers are skilled developers who are experts in writing automated tests. Together with your developers they ensure the quality of the code. They can help you in getting your test effort balanced. They know when and how to do unit and integration testing; stress and performance testing.

Test Lab
The test lab from QualityVision is able to test any software or hardware on any platform.

Why choose QualityVision test lab facilities?
Using our test lab facilities has a lot of advantages:

You do not need to invest in expensive hardware and software designed for testing.
You do not need to hire testers that you have to train and to provide with testing tools, office space, and other resources.
Trained professional testers can speed up the testing phase and still meet your time to market deadlines.
You can benefit from our expert know-how to get your own test lab structured.

How does the test lab work?
A Quality Vision consultant will visit you to get the necessary information. A test plan will be written with the following content:

Scope: What kind of tests are needed: portability testing, installation testing, manual reviews, functional testing, performance testing, usability testing, …. What kind of requirements or specifiations need to be tested?
Test bed and test strategies: environmental conditions, test data conditions, test techniques, stop criteria.
Planning: Depending on the scope, non-scope, resources a detailed milestone plan will be written.
Dependencies and constraints: Not only will the dependencies and constraints be documented but evasive solutions will be documented as well.
Writing a test plan and gathering product information normally takes one week. We try to be as flexible and adaptive as possible. All test cases are documented according to the needs of the client. We report bugs by any error report system of choice.

Software testing

Posted on by admin

It is impossible to test a program completely.

What does it “testing a program completely” mean? Ideally, it means that at the end of the test process, the program will have been tested against all possible eventualities, and that there should not remain any errors in program functionality. All existing problems would have been resolved during the testing process.

In reality, this cannot happen. There are simply too many variables. For example:
• It is not possible to verify the reaction of any program to every combination of input information.
• It is not possible to verify every possible sequence of program workflow.
• It is not possible to reveal all design errors.
• The correctness of a program cannot be always be proved logically.

Then why should programs be tested?

Since it can never be said that a program works perfectly, why should it be tested?
A program should be tested to find the errors in it that can be addressed and solved, increasing efficiency in program functionality and confidence in program usage results.

Small or large, all program errors cost you money and time. Our job is to search for and eliminate errors for you.

Testing improves the quality and performance of any program.

When the majority of errors in a program are found and corrected, the quality of program output is improved, and so is your bottom line. This is the real purpose of testing.

We can participate in testing of program product in any development stage of the project:

Design

• preparation for the testing automation
• development of reception tests
• stability of acquisitions analysis
• initial testing plan development

Realization of base functions

• beginning of nonformal testing
• beginning of the formal core product testing
• first nonformal estimations of tasks, resources, time and budget.

Almost alpha

• determination of testing purposes and tasks, time, resources and budget necessary; creation of prototype testing plan
• risk evaluation for the tested project
• fulfillment of basic testing.

Alpha

• testing all program blocks
• testing under real operating conditions
• nonformal testing of the specific program blocks
• planning and the fulfillment of the detailed tests of the selected program blocks
• test plan revision
• analysis of testing manual and testing according to it
• discussion of specification shortcomings
• estimate amount of remaining errors
• beginning of testing for the hardware compatability
• addition of regression tests.
• the beginning of the automation of testing.

Pre-beta

• testing program for compliance to the requirements for the stability and the completeness of Beta-version.

Beta

• final test plan approval
• the continuation of fulfillment and the deepening of test plan and automation of testing
• rapid repeated testing of the corrected program blocks
• complete cycle of hardware testing
• publication of the formal testing results
• the last analysis of user interface, its preparation for the freezing
• Beta- testing out of the company.

Freezing user interface

• regression testing
• test plan fulfillment
• extended hardware testing

Preparation for the final testing

• regression testing with all possible versions of program environment
• complete cycle of tests according to the plan for the last version of program
• hardware testing
• testing the corrections of old errors
• system reliability evaluation

Last test for integrity

• reliability evaluation during the first day of operation
• real mode testing

• testing the first releases

Release

• continuous testing during entire production period
• testing finished product
Examples of the tests, which we can make during the functional and system testing:

Collation with the specification

The correspondence of the developed program to each word of specification is checked.

Correctness

Testing how correct program makes necessary calculations and produces reports.

Laboratory tests

Hiring several feature users and watching their work with product. Actually Beta-testing is done in an attempt to obtain the same result, but with Beta-testing it is not possible to watch the process, Beta-testing it is much less effective than laboratory tests.

Extreme values

Testing program reaction to the extreme values input.

Productivity

Measuring time elapsed for different tasks, especially those, which clients will use most frequently.

Switching the modes

Testing how correctly program is switching from one mode to another. It is especially important for multitasking systems.

Real mode operation

We work with the program in the same regime as real users would work. The shortcomings, which were missed during the formal testing or they were considered insignificant, in the real work can prove to be very serious.

Load tests

Testing program reaction to extreme operating conditions:

• testing to the maximum volume of the input information
• testing program reaction to an increased activity
• analysis of resources requirements

Multi-user and multitask work

It is checked how product works with the parallel accomplishment of several objectives and how actions of several users are coordinated.

Working/treatment of errors

Testing program reaction to the improper, nonstandard or not predicted actions of users.

Protection

It is checked to see how complicated is it for an unauthorized user to obtain access to the system.

Compatability and format conversion

Testing ability of two products to work with the same data files or ability of successful co-existence in the computer operating memory.

Hardware configurations

Testing program operation on the computers with diverse configurations.

Installation and maintenance

Testing program installation, how simple and convenient and how long does it take on the average to complete the installation.
