When a human is not used for testing a particular module, then it means that we are using a tool for testing and when we use any tool for testing a module then it is known as automated testing. Testing tools facilitate a software tester in different conditions where testing becomes critical. According to the circumstances, we choose software testing tools. There are many tools which are used for software testing like QTP and win runner. Testing tools can be used for different testing activities to automate them. For example, we can use testing tools for Load / Stress tests. Advantage of testing tool is that they save precious time, and also remove the chance for a bug to remain unobserved while testing, but your test cases must also be very powerful because testing tools automate test cases and if your test cases are weak, then testing tools cannot provide better performance. Testing is a process used to help identify the correctness, completeness and quality of developed computer software. With that in mind, testing can never completely establish the correctness of computer software. There are many approaches to software testing, but effective testing of complex products is essentially a process of investigation, not merely a matter of creating and following rote procedure. One definition of testing is “the process of questioning a product in order to evaluate it”, where the “questions” are things the tester tries to do with the product, and the product answers with its behavior in reaction to the probing of the tester. Although most of the intellectual processes of testing are nearly identical to that of review or inspection, the word testing is connoted to mean the dynamic analysis of the product putting the product through its paces.
