Software testing is one of the most important phases of any software development process. Proper testing ensures quality so that it can be used by users. There are different levels of software testing. Each and every level of testing ensures different aspect of software is perfect so that the final application runs error free. Usually, any software is first tested for software adherence to program specifications so that the software can do what it is intended for. This is also called unit testing. The next level of software testing is integration testing where all modules of the application are verified if they communicate well between each other and that the desired end result is achieved. Since most of the complex software applications are made of more than one module, checking for proper integration of the modules and communication between them is important. Another important testing is performance testing. Any application that is developed should undergo application performance management because people will have different software and hardware configurations and that the software should run in all computers without any issues. Incorrect coding and bugs can lead to too much resource consumption even in latest systems which are powered by multiple processors and RAM modules. Bugs can not only lead to system errors but also system freeze which can be devastating to the user. Hence, there should be an effective application performance management so that the software runs smooth and error-free. If you are developing a web application, web application load testing is very important to make sure the web application doesn’t take too much load or crash while running. Web application load testing can become cumbersome if done manually and for this reason, most of the companies resort to automated testing tools which will automatically assess various aspects of the web application and repeat the test for several or preset number of times so that one can find if there is any performance issue with the software. There are many performance testing tools available for this purpose. Most of them are configurable so that they can be used in wide variety of applications. Performance testing tools are very useful for companies that develop highly complex applications. Web application load testing can be automated to perform random tests repeatedly for several hours to find out whether the application being tested passes all possible test scenarios. These tests are essential to maintain software quality throughout the development cycle so that the end product is released on time with the highest quality.
