The primary way to run a performance test locally is to run its host-side entry point. These entry points are defined in src/tests/end_to_end/perf/. These are what are used in Fuchsia Infra builds for collecting performance results for uploading to Chromeperf. Running one of these entry points involves the following:
terminalproduct, in order to match what is tested on Fuchsia Infra in CI and CQ. Example:
fx set terminal.x64-reduced-perf-variation fx build
Launch Fuchsia on hardware or on an emulator as usual.
Run the test's host-side entry point with
fx test --e2e. Example:
fx test --e2e host_x64/fidlc_microbenchmarks_test
The test will write its results to a newly-created, timestamped
out/test_out. This will include
*.fuchsiaperf.json files containing the performance results. It may
include other files such as Fuchsia traces.
