@ -35,6 +35,10 @@ If no test names are given, all tests are run.
-v is incompatible with -g and does not compare test output files.
-r randomizes test execution order. You can use --randseed=int to provide a
int seed value for the randomizer; this is useful for reproducing troublesome
test orders.
-T turns on code coverage tracing with the trace module.
-D specifies the directory where coverage files are put.
