Web Software Testing: Guarantee that the Web Software is purposeful and safe
The software development life cycle contains numerous stages. Software performance testing is one of the significant phases 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. 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. 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. 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.
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. 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 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. The software is incomplete at this point and testing is done only for small modules of the software. Alpha testing is frequently employed for off-the-shelf software as a method of internal 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. 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. 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 developer typing the code is called the driver while the programmer that checks every line of code as it is produced is called the observer or the navigator. 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. 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 needs to be carried out to asses the software compatibility with the software and hardware that it may interact with. This includes testing compatibility with operating systems, database, browsers, peripherals and backwards compatibility.
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.
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 done to find out any of such instances. The above mentioned methods are essential tests to complete the web software testing.
