There is the import-webdriver-tests script to automate most of the process of checking out the repository and copying the files.
It reads the importer.json of the selected suite (selenium or w3c), which contains the desired commit alongside the list of paths to skip/import.
The cloned repository sits in WebKitBuild/ for easier inspection. For example, to manually check the new commit to be imported.
Once chosen the new commit, update importer.json with its hash and eventual path changes (e.g., new folders to be copied or skipped) and run the import script to update the desired suite:
./Tools/Scripts/import-webdriver-tests --selenium` ./Tools/Scripts/import-webdriver-tests --w3c`
After running the script, if you're using git, you can check which files were added with git status WebDriverTests/ to add them to the new commit. One current limitation of the script is its inability to check for deleted files from the source repository, so this step is still manual.
Beware that when importing Selenium tests, some manual intervention might be needed to remove unsupported code related to Firefox, Chrome, etc. For example:
WebDriverTests/imported/selenium/py/selenium/webdriver/__init__.py.RemoteConnection objects in WebDriverTests/imported/selenium/py/selenium/webdriver/remote/webdriver.py.To test the imported suite, run it:
Tools/Scripts/run-webdriver-tests --verbose --wpe --release --display-server=xvfb
