Safari

To run Safari on macOS, some manual setup is required. Some steps are different for Safari and Safari Technology Preview.

• Allow Safari to be controlled by SafariDriver:

  • safaridriver --enable or

  • "/Applications/Safari Technology Preview.app/Contents/MacOS/safaridriver" --enable

• Allow pop-up windows:

  • defaults write com.apple.Safari WebKitJavaScriptCanOpenWindowsAutomatically 1 or

  • defaults write com.apple.SafariTechnologyPreview WebKitJavaScriptCanOpenWindowsAutomatically 1

• Turn on additional experimental features Safari Technology Preview:

  • defaults write com.apple.SafariTechnologyPreview ExperimentalServerTimingEnabled 1

• Trust the certificate:

  • security add-trusted-cert -k "$(security default-keychain | cut -d\" -f2)" tools/certs/cacert.pem

• Set no_proxy='*' in your environment. This is a workaround for a known macOS High Sierra issue.

Now, run the tests using the safari product:

./wpt run safari [test_list]

This will use the safaridriver found on the path, which will be stable Safari. To run Safari Technology Preview instead, use the --channel=preview argument:

./wpt run --channel=preview safari [test_list]

Debugging

To debug problems with safaridriver, add the --webdriver-arg=--diagnose argument:

./wpt run --channel=preview --webdriver-arg=--diagnose safari [test_list]

The logs will be in ~/Library/Logs/com.apple.WebDriver/. See man safaridriver for more information.

To enable safaridriver diagnostics in Azure Pipelines, set safaridriver_diagnose to true in .azure-pipelines.yml.
