Definition:
The test suite is a container that has a set of tests, that help testers in executing and reporting the test execution status. It can take any of the three states, namely: active, in progress and completed. A Test case can be added to multiple test suites and test plans. After creating a test plan, test suites are created which in turn can have any number of tests.
