Web Software Testing: Guarantee that the Web Software is purposeful and safe
The software development life cycle (SDLC) is composed of various stages. Software 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. The testing spans over all the stages in the SDLC. The software itself also comes in different varieties, which all require testing before they’re released on the market.
One variety is software for web applications. The importance of this type of software has increased rapidly since the arrival of the Internet. Most security risks come from Internet. Therefore it’s crucial to test the software thoroughly prior to releasing it on the market.
While web software testing is important, there’s always a rush in developing and testing it. In the design and development stages, testing engineers utilize different groups or types of tests such as 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.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. The software is incomplete at this point and testing is done only for small modules of the software. When of-the-self software is employed, alpha testing is often used as an internal acceptance test. Software that has been alpha tested cannot be released until all the major functional parts have been coded 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.
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.
Two coders working at a single workstation it is at the core of paired programming. 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 fact that the software is tested many times during the development process should provide a bug free software by the end of it. 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. Load testing will provide information regarding the amount of users that could connect simustaneosly to a site, the number of transactions that the system can cope at the same time and its responsiveness under different circumstances or amount of traffic.
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.
The testing used to validate the conformance to specifications and requirements is the Functional testing. This testing involves performing a sequence of tests to validate the behavior of the software, feature by feature using a large number of normal and abnormal data. Regression testing is performed to ensure that enhancements, defect repairs or other changes to the software have not disrupted any existing 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. Regression testing is done to find out any of such instances. The above mentioned methods are essential tests to complete the web software testing.
