Manual Testing Tutorial

Manual testing is one of the earliest type of software testing. Here the tester manually tests the software for defects (performs a set of functional tasks). The tester follows a set of test cases derived from a set of requirements. Here a test plan is followed.

It requires the tester to step into the shoes of the enduser and test the application as if he was to use it.

There are several stages of Manual testing. They are

Unit Testing
Integration Testing
System Testing
User Acceptance Testing

Please find various links related to the different aspects of manual testing on the left hand side.

As “recently as 1998, in one Fortune 100 company, performance testing was conducted while one test engineer sat with a stopwatch, timing the functionality that another test engineer was executing manual testing”. [Elfriede99]

Manual testing is that part of software testing that requires operator input, analysis, or evaluation.

Manual Testing should be documented in great procedural detail. This helps in repeating the tests consistently, in the way they were intended.

Manual Test case generation
The Manual test cases are developed in the implementation phase of the project. Functional specification document, Test Plan and design document are taken as input for the manual test case generation. The manual test case specifies actual input values and expected results. The goal in the generation of manual test cases is to exercise the component’s logic and to setup testing scenarios that will expose errors, omissions and unexpected results. The task is carried out by testers and test lead and verified by Test Manager.

SQA using the exploratory testing method, manually tests and then plans more exhaustive testing and automation.

Manual Test case creation is expensive. Estimates run from 3-10 times the time to create and manually execute a test case.

Tests which are suitable for manual testing are not necessarily suitable for test automation.
