benchmark: test refactoring #31396

BridgeAR · 2020-01-17T08:03:41Z

I went ahead and refactored all our benchmark tests. The benchmark suite itself now has a test functionality built-in (using test). It is also possible to run all benchmark suites by using all. The tests are now run independent from benchmark changes and should always keep on working.

The fixtures directory is now skipped and in case there's a typo for the benchmark, the error message is now more informative.

I removed warnings from benchmark files in case they occurred.

Some tests require special options as a minimum. Those may now be passed through using the test option. These values will be used in case the benchmark test is run.

It is now possible to pass through individual configurations instead of having to use an array.

Fixes: #31083

I did not yet find time to clean up the commits.

benchmark/_test-double-benchmarker.js

      run();
    } else {
      console.log(JSON.stringify({ throughput }));
      if (client) {
        client.destroy();
+        process.exit(0);


@nodejs/http2 @ronag I had to end the process hard in case this runs the http2 benchmarks. Maybe someone could have a look what part stays alive.

This is ready for review. I just cleaned up the commits.

Looks reasonable to me.

This does reduce the test runtime for almost all benchmarks. Mostly by a few hundred milliseconds. The runtime for test-benchmark-async-hooks is reduced more significantly from ~6 to ~1 seconds and test-benchmark-module from ~3 to ~1 seconds.

BridgeAR · 2020-01-22T14:20:00Z

This could use another review @nodejs/benchmarking

Trott · 2020-01-27T06:36:26Z

Needs a rebase.

Trott

Rubber-stamp LGTM. The concept is sound.

This is the basis to refactor the helper to use modern class language features such as private fields. It also refactors the exports to use module.exports. That way it's immediately clear what parts are exported.

Also something that I just now noticed is that this PR changed the formatting of the configuration string (when writing the CSV output) such that each parameter is preceded by a space whether it's needed or not, which breaks tooling (something I'm currently working on) that monitors changes in benchmark results by comparing results for a particular configuration.

Just something to keep in mind if these changes get merged again later on.

EDIT: FWIW I'm now incorporating extra safeguards to prevent this sort of thing in my tooling in the future...

This adds a new `test` option. Using it automatically uses a single minimal option matrix to verify the benchmark works as expected. Using the new `all` option makes sure all test suites are run. On top of that the benchmarks will from now on report properly what category might have a typo, if any. The http duration was also refactored to use a option instead of relying on a configuration setting. The fixture folder is ignored as test suite from now on.
