To run WPT on WebView on an Android device, some additional set-up is required.
Currently, Android WebView support is experimental.
Please check Chrome for Android for the common instructions for Android support first.
Ensure you have a userdebug or eng Android build installed on the device.
Install an up-to-date version of system webview shell:
chrome-android.zip
file and unzip it.SystemWebViewShell.apk
.If you have an issue with ChromeDriver version mismatch, try one of the following:
_venv/bin/chromedriver
such that wpt runner can install a matching version automatically. Failing that, please check your environment path and make sure that no other ChromeDriver is used../wpt run --webdriver-binary <binary path> ...
Configure host remap rules in the webview commandline file:
adb shell "echo '_ --host-resolver-rules=\"MAP nonexistent.*.test ^NOTFOUND, MAP *.test 127.0.0.1\"' > /data/local/tmp/webview-command-line"
Ensure that adb
can be found on your system's PATH.
Example command line:
./wpt run --test-type=testharness android_webview <TESTS>
Note that there is no support for channel or automatic installation. The test will be run against the current WebView version installed on the device.
Reftests are not supported at the moment.
