# When fuzzing, T.Parallel should be safe to call, but it should have no effect.
# We just check that it doesn't hang, which would be the most obvious
# failure mode.
# TODO(jayconrod): check for the string "after T.Parallel". It's not printed
# by 'go test', so we can't distinguish that crasher from some other panic.

# Run the test without fuzzing, setting -parallel to different values to make
# sure it fails, and doesn't hang.
