	-list regexp
	    List tests, benchmarks, fuzz tests, or examples matching the regular
	    expression. No tests, benchmarks, fuzz tests, or examples will be run.
	    This will only list top-level tests. No subtest or subbenchmarks will be
	    shown.

	-parallel n
	    Allow parallel execution of test functions that call t.Parallel, and
	    fuzz targets that call t.Parallel when running the seed corpus.
