Web Software Testing: Guarantee that the Web Software is purposeful and safe
The software development life cycle contains numerous stages.Software testing is one of the most essential stages. 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. 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.
One variety is software for web applications. The importance of this type of software has increased rapidly since the arrival of the Internet. The majority of the security threats start off from Internet and it is necessary to make sure that the web software is carefully tested prior to releasing to the costumer.
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.There are different methods that the test engineers use to test this software. They are code testing, load testing, compatibility testing, functional testing and regression testing.
The standanrd pattern for the realease of web software consists of two main stages, alpha and 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.Alpha testing is often used for ready to use software as a type of in-house acceptance testing. Software that passed the alpha test will not be released till all the major functionalities of the software are built and tested.
Beta testing is done by a limited amount of users that can use the software before its official release takes place. In case of website design it is easy to put together the various pages as the website design uses HTML. So the alpha/beta technique is generally 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 popular methods used by highly qualified technicians to achieve error 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. This strategy is appealing because fewer bugs are produced. According to The Economist, “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 performed against heavy loads or inputs such as multiple user log-ins and mail servers to determine the point at which the web-site/application fails or the point when performance degrades. This type of testing will help to arrive at statistics such as how many users the site will sustain at the same time, the quantity of communication it will hold and the reaction time under various circumstances.
Compatibility testing evaluates the application’s compatibility with the computing environment like the operating system, database, browser compatibility, backwards compatibility, computing capacity of the hardware platform and compatibility of 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. In this type of development, the developer adds another module with some functionality to the existing module that’s running. One should make sure that adding this module does not ruin the existing functionality. Regression testing is performed for the purpose of discovering regression bugs. The above tests are essential for completing web software testing.
