The IDETester package provides a view inside Lazarus from which you can run your FPCUnit test cases.
IDETester is a better approach than the standard FPC GUI Test Runner for several reasons:
* having the state of tests open in the IDE itself makes working with test state a more natural extension of your work flow
* The IDE Tester view remembers the state of tests across multiple iterations saving considerable time when your tests cases take more than a little time to run
* The IDE Tester state is integrated into the Project and remembered across project editing sessions
