Web Software Testing

The software development life cycle (SDLC) is composed of various stages. Software performance testing is one of the significant phases within the software development cycle (SDCL). There are different testing types and they are useful at different stages of the software development cycle. These methods are employed during various stages of the SDLC. The software itself also comes in different varieties, which all require testing before they’re released on the market.

There are many different classes of software and software for web applications is one of them. With the advent of the Internet web software has significantly increased in importance, as the Internet has had a substantial impact on our daily lives. Because of the high impact Internet has on our daily lives any web software is carefully tested before launching in order to reduce the associated security risks that originate from the use of the Internet.

Even though the testing of web software is vital, there is at all times rush in building and testing those application due to time constraints. The different types of tests can be grouped in code testing, load testing, compatibility testing, functional testing and regression testing.

The web software is usually released by means of a model of software release known as alpha/beta testing.The first stage or alpha testing takes place at the developers’ site where either potential users/customers or a purposely created indepent test team will interact with a simulated or actual operational version of the software being tested. Because during alpha testing the software is actually still being developed only small modules of the software are tested during this stage.Alpha testing is often used for ready to use software as a type of in-house acceptance testing. Software that has been alpha tested cannot be released until all the major functional parts have been coded and tested.

Beta testing is done by a limited amount of users that can use the software before its official release takes place. Since the web site design uses HTML coding, it’s easy to integrate individual web pages on site; hence the alpha/beta method is usually not used for website development This imply that it is possible to build and test one page at a time and later go to the next one with independent testing for each one.

When software testers or development engineers are code testing they are checking for the presence of software bugs. Because the time involved in web development is small it is important that the software is free of bugs. Paired-programming is one of the favourite methods that highly qualified testers can use to produce bug free coding.

The Paired programming is a method in software development where two programmers work simultaneously at one keyboard. One programmer types in the code when the other person observes and reviews each line at the same time. The judgment behind taking up this method is the following. The Economist proclaims that, “Laurie Williams of the University of Utah in Salt Lake City has shown that paired programmers are only 15% slower than two independent individual programmers, but produce 15% fewer bugs.”

The testing process continues through out the software development cycle so that at the time of final release it is free of bugs. Load testing is done to see at what point the application fails or the performance reduces when under heavy loads such as multiple users on or heavy server traffic. The testing documents the number of users the site will support simultaneously, the number of transactions it can handle and its response time under various conditions or traffic flows.

Compatibility testing needs to be carried out to asses the software compatibility with the software and hardware that it may interact with. This includes testing compatibility with operating systems, database, browsers, peripherals and backwards compatibility.

Functional testing confirms its specifications and accurately performs all of the required tasks. This involves doing a series of tests that perform a feature by feature validation of behavior, utilizing a wide range of normal and erroneous input data. Regression testing is carried out to check that any changes made to the code in order to enhance it or to fix defects has not affected any functionality.

Regression testing is an important testing method when the software development method is iterative. In iterative programming, new modules are added to the core module to increase the functionality provided by the application, this needs to be done with the certainty that the added module does not affect the original functionality of the running module. Regression testing is performed for the purpose of discovering regression bugs. The above tests are essential for completing web software testing.
