Web Software Testing
There are various phases in software development life cycle (SDLC). Software testing is an important stage within the software development cycle (SDCL). A variety of testing methods are used beginning with the application's development until it gets the marketing stage. From the initial development of the application until it reaches the maketing phase different testing types will be used. In addition, all the different versions of the software have to be tested before they are delivered to either the costumer or the target market.
Software for web applications is one type of software. 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. Most security risks come from Internet. Therefore it's crucial to test the software thoroughly prior to releasing it on the market.
The time available to develop and test web software is always limited. While the web software is being designed and developed it is also being tested by the testings engineers using different types of tests. 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 using a pattern of software release known as alpha/beta testing.This is a simulated or actual operational test conducted by potential users or an independent test team at the developers' site. Because during alpha testing the software is actually still being developed only small modules of the software are tested during this stage. Software that passed the alpha test will not be released till all the major functionalities of the software are built and tested.
After the alpha testing stage is finished, the software advances to the beta phase of testing. The web software should be fully completed by now. The software is released to a restricted number of users for testing before it is officially released. 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.
In code testing the software testing or development engineer examines the codes for software bugs. Web development is a very rapid process so the abscence of bugs is required. Paired-programming is one of the favourite methods that highly qualified testers can use to produce bug free coding.
Paired programming is a software development method in which two programmers work together at one keyboard. One programmer types in the code when the other person observes and reviews each line at the same time. Support for this methodology is provided by some research data produced by Laurie Williams at University of Utah in Salt Lake City. According to this research paired programmers produce code with 15% less bugs while only being 15% slower than individual programmers.
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.
The testing done to estimate the compatibility of the application with the different interacting hardware of software is the Compatibility testing. This method tests how good the software is in interactions with operating system, peripherals, database, browser etc. It also tests the computing capacity of the hardware platform and the peripherals.
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 very important whenever there's iterative development of software. Iterative software development is a method in which new functionality is added to existing software. In this case one should make sure that the new addition has not affected any of the existing functionality. All the types of test mentioned above are necessary to provide complete web software testing.
