I wanted to know that what is the exact purpose of "TestPlan" in Silk Test? As we can run test cases using test scripts, then what we use "Test Plan" for ? Is it a "Test Case Repository" but then how can we run test cases from there ?
Your views and comments are always welcome !!!
A testplan is used to organize your tests. If you have multiple tests in multiple script files you can combine them together with a test plan.
For example, our acceptance test covers many areas of our application. Each area has its own test script containing multiple testcases. We then use a test plan to tie it all together.
See the help file for "Overview of testplans". Might also want to actually read the tutorial. Page 54 has a section on test plans. You might want to start with the tutorial before trying to go too far on your own. You might learn some faster ways to get things done.
