Web Software Testing: Guarantee that the Web Software is purposeful and safe
The software development life cycle contains numerous stages. 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. 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. Most security risks come from Internet. Therefore it’s crucial to test the software thoroughly prior to releasing it on the market.
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.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 web software is usually released by means of a model of software release known as alpha/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. After being alpha tested software will only be released when all the main functional sections have been both coded and tested.
Beta testing is done by a limited amount of users that can use the software before its official release takes place. The alpha/beta testing method is not the standard procedure when testing web site design. 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. A popular method used by experienced programmers for bug free coding is the paired-programming.
Two coders working at a single workstation it is at the core of paired programming. The driver types in the code while the observer or navigator reviews each line. 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 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 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.
