Manual testing is a sort of software testing in which test cases and scenarios are executed manually using human intuition and precision. During manual testing, testers typically examine the program or application being evaluated, look for defects, and report issues to the development team for resolution.
With a focus on comprehensive testing, manual meticulously evaluate every feature of your product, identifying bugs and inconsistencies that automated methods may overlook.
When an application is development, there are high chances of it being full of errors or bugs. Testing an application before it finally makes its way to the market is must. This prevents any critical issue from occurring when the application is in the hands of the end-users.
One round of testing is assuring that the application is bug free and stable and deliver a quality product to the client, because if the application is bug free, the end-user will use the application more conveniently.
If the test engineer does manual testing, he/she can test the application as an end-user perspective and get more familiar with the product, which helps them to write the correct test cases of the application and give the quick feedback of the application.
