General instruction on running and debugging benchmarks can be found in the tools/perf/README.md.
Fuchsia uses web_engine_shell to run integration tests. Be sure to build any components you wish to deploy on your device, along with web_engine_shell.
The list of supported benchmarks can be found in the bot_platforms.py.
The list of stories that are skipped can be found in expectations.config, with the fuchsia tag.
NOTE This has not been tested as these instructions were developed while remote work was the only available option.
After building chromium, be sure to have a device that has gone through OOBE attached to the host. Run the following from the chromium build directory if you want to run a specific benchmark:
$ ../../content/test/gpu/run_telemetry_benchmark_fuchsia.py \ --browser=web-engine-shell --output-format=histograms \ --experimental-tbmv3-metrics -d [--repo=/path/to/fuchsia/out/dir --no-repo-init] \ # Deploy custom Fuchsia. [benchmark] [--story-filter=<story name>]
For instance, to run the simplest story, load:chrome:blank from the benchmark system_health.memory_desktop:
$ ../../content/test/gpu/run_telemetry_benchmark_fuchsia.py \ --browser=web-engine-shell --output-format=histograms \ --experimental-tbmv3-metrics -d system_health.memory_desktop \ --story-filter=load:chrome:blank
If no benchmark or filter is specified, all supported benchmarks will run.
If you wish to run the tests on an emulator, simply drop the -d flag. This will start an emulator and run through the supported tests, like so.
$ ../../content/test/gpu/run_telemetry_benchmark_fuchsia.py \ --browser=web-engine-shell --output-format=histograms \ --experimental-tbmv3-metrics system_health.memory_desktop \ --story-filter=load:chrome:blank
Note that this needs to be run from an x64 build directory.
As connecting to a device that is not connected to a workstation is more common, this flow is what is recommended and tested.
Be sure to first open a tunnel to your device:
$ ../../content/test/gpu/run_telemetry_benchmark_fuchsia.py \ --browser=web-engine-shell --output-format=histograms \ --experimental-tbmv3-metrics -d --target-id=[::1]:8022 \ [benchmark] [--story-filter=<story name>]
See the above section on how to use the benchmark and --story-filter.
