Keen infotech is provide Manual Softwre Testing is the process of manually testing software for defects. It requires a tester to play the role of an end user whereby they utilise most of the application’s features to ensure correct behavior. To guarantee completeness of testing, the tester often follows a written test plan that leads them through a set of important test cases.

A key step in the process is, testing the software for correct behavior prior to release to end users. For small scale engineering efforts (including prototypes), exploratory testing may be sufficient. With this informal approach, the tester does not follow any rigorous testing procedure, but rather explores the user interface of the application using as many of its features as possible, using information gained in prior tests to intuitively derive additional tests. The success of exploratory manual testing relies heavily on the domain expertise of the tester, because a lack of knowledge will lead to incompleteness in testing. One of the key advantages of an informal approach is to gain an intuitive insight to how it feels to use the application. Large scale engineering projects that rely on manual software testing follow a more rigorous methodology in order to maximize the number of defects that can be found. A systematic approach focuses on predetermined test cases and generally involves the following steps.[1] Choose a high level test plan where a general methodology is chosen, and resources such as people, computers, and software licenses are identified and acquired. Write detailed test cases, identifying clear and concise steps to be taken by the tester, with expected outcomes. Assign the test cases to testers, who manually follow the steps and record the results. Author a test report, detailing the findings of the testers. The report is used by managers to determine whether the software can be released, and if not, it is used by engineers to identify and correct the problems.
