Servo Page Load Time Test
Prerequisites
- Python3
Basic Usage
./mach test-perf can be used to run a performance test on your servo build. The test result JSON will be saved to etc/ci/performance/output/. You can then run python test_differ.py to compare these two test results. Run python test_differ.py -h for instructions.
Setup for CI machine
CI for Servo
- Setup your Treeherder client ID and secret as environment variables
TREEHERDER_CLIENT_IDandTREEHERDER_CLIENT_SECRET - Run
./mach test-perf --submitto run and submit the result to Perfherder.
CI for Gecko
- Install Firefox Nightly in your PATH
- Download geckodriver and add it to the
PATH pip install selenium- Run
python gecko_driver.pyto test - Run
test_all.sh --gecko --submit
How it works
- The testcase is from tp5, every testcase will run 20 times, and we take the median.
- Some of the tests will make Servo run forever, it's disabled right now. See https://github.com/servo/servo/issues/11087
- Each testcase is a subtest on Perfherder, and their summary time is the geometric mean of all the subtests.
- Notice that the test is different from the Talos TP5 test we run for Gecko. So you can NOT conclude that Servo is "faster" or "slower" than Gecko from this test.
Unit tests
You can run all unit tests (include 3rd-party libraries) with python -m pytest.
Individual test can be run by python -m pytest <filename>:
test_runner.pytest_submit_to_perfherder.py
Advanced Usage
Test Perfherder Locally
If you want to test the data submission code in submit_to_perfherder.py without getting a credential for the production server, you can setup a local treeherder VM. If you don't need to test submit_to_perfherder.py, you can skip this step.
- Add
192.168.33.10 local.treeherder.mozilla.orgto/etc/hosts git clone https://github.com/mozilla/treeherder; cd treeherdervagrant upvagrant ssh./bin/run_gunicorn
- Outside of vm, open
http://local.treeherder.mozilla.organd login to create an account vagrant ssh./manage.py create_credentials <username> <email> "description", the email has to match your logged in user. Remember to log-in through the Web UI once before you run this.- Setup your Treeherder client ID and secret as environment variables
TREEHERDER_CLIENT_IDandTREEHERDER_CLIENT_SECRET
Troubleshooting
If you saw this error message:
venv/bin/activate: line 8: _OLD_VIRTUAL_PATH: unbound variable
That means your virtualenv is too old, try run pip install -U virtualenv to upgrade (If you installed ubuntu's python-virtualenv package, uninstall it first then install it through pip)
