Explain Test Plan module in Quality Center (QC).

In Test Plan module by creating a folder one can create test manually or automatically for all the requirements.

In the folder an empty test was created, based on the test the corresponding functional tool (QTP or Load runner) was launched to generate test scripts. Click save button. The test script will be saved in the empty script file created in QC. Likewise it has to be created for all the tests.

After creating all the tests, a link between the test and corresponding requirement with the help of requirements coverage tab can be created, this would be helpful for automatic traceability.
