Web Software Testing: Ensuring Web Software Security and Functionality
There are various phases in software development life cycle (SDLC). Software performance testing is one of the significant phases within the software development cycle (SDCL). Different types of testing are employed in each phase beginning with development till it reaches the market. 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.
Software for web applications is one type of software. With the advancements in Internet and its high impact on our day to day life, web software has achieved high importance in software industry and 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.
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.Alpha testing is a replicated or real ready testing by would-be users/customers or a separate testing team on the developers’ location. This testing will be upon incomplete software and will be tested for small parts of the software. 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. 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 means they can build and test one page at a time. After completion they can move onto the next one, with each page independent of each other.
When software testers or development engineers are code testing they are checking for the presence of software bugs. Web development is a very rapid process so the abscence of bugs is required. 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. 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.”
As the development process continues the software is tested repeatedly. By the time it’s finally released the software is free of bugs. Load testing is used to check if a web-site/application will fail or loss performance under the added pressure of heavy loads or imputs from multiple users log-in, mail servers, etc. 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 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 performed to ensure that enhancements, defect repairs or other changes to the software have not disrupted any existing functionality.
When interative methodology is used to develop software regression testing is crucial. 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. All the types of test mentioned above are necessary to provide complete web software testing.
