Does anyone have tools or experience with code coverage for PL/SQL. I believe this is possible using DBMS_PROFILER?
See SD Test Coverage Tools. We're about to release a PLSQL test coverage tool with the same capabilities as our other tools, including a GUI to display the results on top of your source code, and a generated coverage report that collects details on individual functions as well as rollups for packages.
EDIT 2/15/2011: PLSQL test coverage production tool is available.
