Commit b81dd80e8cb77046b6196a1dec3f8f356307fcfb
2008-11-03T18:38:12
Change test_main to run a single test case out of the suite By passing the name of the test function on the command line we execute exactly that one test, and then exit successfully if the test did not fail. This permits multiple functions in the same .c file, so they could be called from a shell script or debugged independently externally. Signed-off-by: Shawn O. Pearce <spearce@spearce.org>
