What is Manual Testing?

Manual testing services company is a software testing process in which test cases are executed manually without using any automated tool. All test cases executed by the tester manually according to the end user's perspective. It ensures whether the application is working, as mentioned in the requirement document or not. Test cases are planned and implemented to complete almost 100 percent of the software application. Test case reports are also generated manually.

Manual Testing Services in India is one of the most fundamental testing processes as it can find both visible and hidden defects of the software. The difference between expected output and actual output given by the software, is defined as a defect. The developer fixed the defects and handed it to the tester for retesting.

Manual testing is mandatory for every newly developed software before automated testing. Automation testing does not replicate the minds of humans, and since humans are the ones using the software, manual testing is a necessary part of building software application. This testing requires great efforts and time, but it gives the surety of bug-free software. Manual Testing requires knowledge of manual testing techniques but not of any automated testing tool.
