Web Software Testing: Guarantee that the Web Software is purposeful and safe

There are various phases in software development life cycle (SDLC). Software performance testing is one of the most essential stages. 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 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. 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 has been alpha tested cannot be released until all the major functional parts have been 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.

Code testing refers to the process where the testing or development engineer verifies the code and make sure that there are no 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 .

The Paired programming is a method in software development where two programmers work simultaneously 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 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 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. The Regression testing the type of testing done to make sure that improvement, defect corrections or any additional changes to the software has not broken down 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.
