Testing Tools and its Uses
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.
Testing helps is Verifying and Validating if the Software is working as it is intended to be working. Thins involves using Static and Dynamic methodologies to Test the application. There are different kinds of testing tools for different purposes. Some of the most common tools are mentioned here.
- QA testing tools
- Load testing tools
- Performance testing tools
- Product testing tools
- Unit testing tools
- Software testing tools
In order to maintain the standards and specifications for a particular system, quality assurance tools are used .These tools help in providing customer satisfaction by meeting their requirements and ensuring that no defects are present in the system. Load testing tools help in understanding the response of the system under heavy loads. These tools create a virtual environment under which the parameters of the actual system are tested. Performance testing tools ensure that a system is running efficiently and smoothly. A faster response time and accuracy is always desirable. This tool helps in estimating the performance of the system in quite a precise manner. Product testing tools are used at every stage of development of a system. This not only enhances the quality of a product but also helps in keeping a check on the profit-loss margin. Software testing tools are used to test an application or even a small program to detect bugs and avoid failure.
Testing objectives include
- Testing is a process of executing a program with the intent of finding an error.
- A good test case is one that has a high probability of finding an as yet undiscovered error.
- A successful test is one that uncovers an as yet undiscovered error.
Testing should systematically uncover different classes of errors in a minimum amount of time and with a minimum amount of effort. A secondary benefit of testing is that it demonstrates that the software appears to be working as stated in the specifications. The data collected through testing can also provide an indication of the software’s reliability and quality. But, testing cannot show the absence of defect — it can only show that software defects are present.
