To run a DEFTEST, place the cursor somewhere inside it and pick "Run DEFTEST under cursor" from the debug menu or press SHIFT-F11. Tests run in this way will stop on PANICs and other error conditions.

To run every DEFTEST in the current document's library, pick "Run DEFTESTs in library" from the debug menu or press CTRL-SHIFT-F11. Tests run in this way will fail silently on PANICs and other error conditions, and a table of results will be shown.
