The Necessity And Use Of Automated Testing Tools Software
Software testing has become an integral part of any software development process. It has become inevitable for the stakeholders or clients to get their software tested before it is bought so that they can have their share of guarantee and satisfaction. In today's world the developers and testers work together as a team in a number of software development companies. It is also seen that the inclusion of software testing at the development stage of the software has many advantages. Automated testing tools software helps in making the process of software development more efficient and in the long run less time consuming.
The term 'software testing' refers to the process of finding out the quality of any given computer software and the term 'quality' used here refers to attributes like security issues, correctness and completeness of the software. It also includes technical issues like portability, efficiency, reliability, capability, usability, compatibility and maintainability. Software testing can also be seen as technical investigation. The investigation is done in order to bring out all possible data regarding the quality aspect of the computer software.
There was a time when software was checked manually i.e. every test case was designed by a human and was fed to the software to check it's reaction (right or wrong) to the given set of test cases. But then, the complexity and the level of sophistication of the software was much lower than what it is today. It was possible to design a comprehensive set of test cases which revealed a reasonable amount of information regarding the quality of the software.
But nowadays, it is virtually an impossible task for a human alone to design a set of test cases which can test the software even for a reasonable amount of variations and complexity. Also, even if a human specializes in the field of test case generation, the process becomes more time consuming and the process of performance testing becomes the bottleneck of the overall process of software development.
The various software testing tools control the execution of the tests which are done on the software required to be tested. They also control the process of comparison of predicted results to the actual results; the process of setting up preconditions for the test to be performed, and other test reporting and test control functions. It is like automating a process which was manual, using a testing process which is formalized and is already working. The challenge with the process of test automation lies in the development of the computerized test oracles (an oracle is a principle or mechanism which can recognize a problem in the product.)
An Automated software testing tool helps the testers in increasing their productivity to a large extent as manual testing is much more time consuming. Although, manual testing is inevitable when newer versions of software are developed and have new features, nowadays tools are available that aid the testers in GUI automation which reduce test time and cost, and other tools for test automation help in test execution.
