Overview
Comment:profiler - Tkt [0dd4b31bb8] T More testsuite cleanup, and fix. Moved all the common setup/teardown into a helper procedure and updated all tests Further fixed the package initialization done by the helper as the original code was able to use the wrong implementation. Now explicitly sourcing the code under test.
