testing: display ops/s

[tj]

Most people obviously feel differently :D but I think it would be nice, even if it's a flag. Almost everything we evaluate is tied back to metrics that are already reported as ops/s in various tools.

Are you referring to the benchmarks in $GOROOT/test/bench, the testing package's benchmarking feature, or something else?

[minux]

I think the OP means benchmarks using the testing package.

[tj]

derp, there we go haha. Yeah just the test -bench output. I'm almost always curious what the ops/s are and manually converting over from nano so it gets a little awkward when you do that reasonably often.

@tj What about writing a simple wrapper for that and share it in some repository?

See https://github.com/golang/tools/blob/master/benchmark/parse/parse.go on how to parse benchmark output. I guess this parser will be maintained for quite some time, since https://github.com/golang/tools/blob/master/cmd/benchcmp relies on it.

@nightlyone hmm I'm not opposed to it, but with the general out-of-the-box experience Go provides it seems a little odd to me.

If we went that route maybe a json output flag makes more sense, so it's not such an ad-hoc format to parse? That would be handy for CI too

JSON output might be useful, but in the meantime one can use golang.org/x/tools/benchmark/parse to parse the output and transform it in whatever ways one desires.

I wouldn't be opposed to a flag to switch the output. cc @robpike

Adding -json for go test and the testing package is #2981.

Nice, interfaces would definitely be better in this case, wrapping the exec is pretty extreme for one metric. I'll close this and see if I can get time to get a patch for that other issue
