cargo test -q not works as expected

[davemilter]

cargo test --help promise "-q, --quiet No output printed to stdout",
but cargo test -q and cargo test produce the same output to terminal.

Thanks for the report! Could you gist the output that's getting printed as well?

I've expected not output at all from cargo test -q, or may be errors to stderr,
like cargo test > /dev/null

Ah this is all output coming from the test harness in rust-lang/rust, which Cargo doesn't forward arguments like -q to righ tnow.
