Running a performance test ========================== You can run `perftest` locally or in Mozilla's CI Running locally --------------- Running a test is as simple as calling it using `mach perftest` in a mozilla-central source checkout:: $ ./mach perftest The `mach` command will bootstrap the installation of all required tools for the framework to run, and display a selection screen to pick a test. Once the selection is done, the performance test will run locally. If you know what test you want to run, you can use its path explicitly:: $ ./mach perftest perftest_script.js `mach perftest` comes with numerous options, and the test script should provide decent defaults so you don't have to bother with them. If you need to tweak some options, you can use `./mach perftest --help` to learn about them. Running in the CI ----------------- You can run in the CI directly from the `mach perftest` command by adding the `--push-to-try` option to your locally working perftest call. This call will run the fuzzy selector and then send the job into our CI:: $ ./mach perftest --push-to-try We have phones on bitbar that can run your android tests. Tests are fairly fast to run in the CI because they use sparse profiles. Depending on the availability of workers, once the task starts, it takes around 15mn to start the test. .. warning:: If you plan to run tests often in the CI for android, you should contact the android infra team to make sure there's availability in our pool of devices.
