npm run build - Runs the tasks necessary for a release. These may include building JavaScript, SASS, CSS minification, and language files.

Unit tests

Running PHP unit tests in your local dev environment

1. Install prerequisites: composer, git, xdebug, svn, wget or curl, mysqladmin
2. cd into the woocommerce-google-analytics-integration/ plugin directory
3. Run composer install
4. Run bin/install-unit-tests.sh <db-name> <db-user> <db-pass> [db-host] [wp-version] [wc-version] [skip-database-creation] e.g. bin/install-unit-tests.sh wordpress_test root root localhost latest latest
5. Run XDEBUG_MODE=coverage vendor/bin/phpunit --coverage-text to run all unit test

For more info see: WordPress.org > Plugin Unit Tests.

E2E Testing

E2E testing uses wp-env which requires Docker.

Make sure Docker is running in your machine, and run the following:

npm run wp-env:up - This will automatically download and run WordPress in a Docker container. You can access it at http://localhost:8889 (Username: admin, Password: password).

To install the PlayWright browser locally you can run: npx playwright install chromium

Run E2E testing:

• npm run test:e2e to run the test in headless mode.
• npm run test:e2e-dev to run the tests in Chromium browser.

To remove the Docker container and images (this will delete everything in the WordPress Docker container):

npm run wp-env destroy

⚠️ Currently, the E2E testing on GitHub Actions is only run automatically after opening a PR with release/* branches or pushing changes to release/* branches. To run it manually, please visit here and follow this instruction to do so.

Coding standards checks

1. Run composer install (if you haven't done so already)
2. Run npm run lint:php

Alternatively, run npm run lint:php:diff to run coding standards checks agains the current git diff. An explanation of output can be found here e.g. what are the S's?

• Hooks defined or used in Google Analytics for WooCommerce

Consent Mode

The extension sets up the default state of consent mode, denying all parameters for the EEA region. You can append or overwrite that configuration using the following snippet:

add_filter( 'woocommerce_ga_gtag_consent_modes', function ( $consent_modes ) {
    $consent_modes[] =
		array(
            'analytics_storage' => 'granted',
            'region'            => array( 'ES' ),
        );
    $consent_modes[] =
        array(
            'analytics_storage' => 'denied',
            'region'            => array( 'US-AK' ),
        );
   return $consent_modes;
} );

After the page loads, the consent for particular parameters can be updated by other plugins or custom code, implementing UI for customer-facing configuration using Google's consent API (gtag('consent', 'update', {…})).

Cookie banners & WP Consent API

The extension does not provide any UI, like a cookie banner, to let your visitors grant consent for tracking. However, it's integrated with WP Consent API, so you can pick another extension that provides a banner that meets your needs.

Each of those extensions may require additional setup or registration. Usually, the basic default setup works out of the box, but there may be some integration caveats. Here are a couple of the most frequent ones:

GA4W overwrites the consent mode defaults set by the other extension

If the additional extension you chose sets its own default state of consent modes, different than the one we set, and you would like to make sure we'll not overwrite that, you can use the woocommerce_ga_gtag_consent_modes snippet to change or disable our setup:

add_filter( 'woocommerce_ga_gtag_consent_modes', function ( $consent_modes ) {
   return array();
} );

I want to stop firing the page_view event on the page load

This is actually unrelated to the consent mode; it's a matter of the default tag config. You can alter it using the woocommerce_ga_gtag_config snippet

add_filter( 'woocommerce_ga_gtag_config', function ( $config ) {
    $config['send_page_view'] = false;
   return $config;
} );
