Composer error on Automattic\Jetpack\Autoloader\AutoloadGenerator

A recent change in composer 2.0.7 made our autoloader incompatible with the new AutoloadGenerator signature. Try to downgrading to composer 2.0.6 by using composer self-update 2.0.6.

VVV: HostsUpdater vagrant plugin error

		...vagrant-hostsupdater/HostsUpdater.rb:126:in ``digest': no implicit conversion of nil into String (TypeError)

	

You might be running an unsupported version of Vagrant. At the time of writing, VVV works with Vagrant 2.2.7. Please check VVV’s requirements.

VVV: install-wp-tests.sh error

		mysqladmin: CREATE DATABASE failed; error: 'Access denied for user 'wp'@'localhost' to database 'wordpress-one-tests''

	

To fix:

• Open MySQL with sudo mysql.
• Run GRANT ALL PRIVILEGES ON * . * TO 'wp'@'localhost';. Exit by typing exit;.
• Run the install-wp-tests.sh script again.

Timeout / 404 errors while running e2e tests

		 Store owner can complete onboarding wizard › can complete the product types section

    TimeoutError: waiting for function failed: timeout 30000ms exceeded

      1 | export const waitForElementCount = function ( page, domSelector, count ) {
    > 2 | 	return page.waitForFunction(
        | 	            ^
      3 | 		( domSelector, count ) => {
      4 | 			return document.querySelectorAll( domSelector ).length === count;
      5 | 		},

	

Timeouts or 404 errors in the e2e tests signal that the existing build might be broken. Run npm install && npm run clean && npm run build to generate a fresh build. It should also be noted that some of our npm scripts also remove the current build, so it’s a good practice to always run a build before running e2e tests.

Docker container couldn’t be built when attempting e2e test

		Thu Dec  3 11:55:56 +08 2020 - Docker container is still being built
Thu Dec  3 11:56:06 +08 2020 - Docker container is still being built
Thu Dec  3 11:56:16 +08 2020 - Docker container is still being built

npm ERR! @woocommerce/e2e-environment@0.1.6 test:e2e: `bash ./bin/wait-for-build.sh && ./bin/e2e-test-integration.js`
npm ERR! Exit status 1

	

Ensure that Docker is running. While the script says Docker container is still being built, it is not actually responsible for running Docker; it’s just waiting for an existing docker instance to respond. Run npm run docker:up if it’s not.

Set up WooCommerce Payments dev mode

Add this to wp-config.php:

		define( 'WCPAY_DEV_MODE', true );

	

Also see this document.

WooCommerce Admin install timestamp

To get the install timestamp (used in wc_admin_active_for() in NoteTraits for example) try this SQL:

		SELECT * FROM wp_options WHERE option_name = 'woocommerce_admin_install_timestamp'

	

Reset the onboarding wizard

Delete the woocommerce_onboarding_profile option:

		DELETE FROM wp_options WHERE option_name = 'woocommerce_onboarding_profile'

	

Enable tracks debugging in the console

		localStorage.setItem( 'debug', 'wc-admin:tracks' );

	

and set Chrome’s log level “verbose” to checked.

Running PHP unit tests using Vagrant (VVV)

1. SSH into Vagrant box (vagrant ssh)
2. cd /srv/www/<WP_INSTANCE>/public_html/wp-content/plugins/woocommerce-admin
3. Set up: bin/install-wp-tests.sh wc-admin-tests root root
4. Fast tests: ./vendor/bin/phpunit --group fast
5. All tests: ./vendor/bin/phpunit

You might need to composer install if phpunit doesn’t exist.

Show the welcome modal again

Delete the option woocommerce_task_list_welcome_modal_dismissed:

		DELETE FROM wp_options WHERE option_name = 'woocommerce_task_list_welcome_modal_dismissed'
