It is possible that users may not see a dropdown containing any Test plans. In this situation all links (except lead enabled ones) will be unlinked. If you are in this situation you must contact a lead or admin to grant you the proper project rights or create a Test Plan for you.
This section is where users can execute test cases (write test results) and print Test case suite of the Test Plan. This section is where users can track the results of their test case execution.
This section, which is only lead accessible, allows users to administrate test plans.
Administering test plans involves creating/editing/deleting plans,
adding/editing/deleting/updating test cases in plans, creating builds as well as defining who can
see which plan.
Users with lead permissions may also set the priority/risk and ownership of
Test case suites (categories) and create testing milestones.
