As of March 2020, GitHub seems to remove the default MySQL installation from its ubuntu-latest container. Now it’s required to set up the database service in order to use it.
Because we at BracketSpace are testing our WordPress plugins with PHPUnit it’s required to run them along with the database.
Let me show you how to set up the GitHub workflow file to use multiple PHP versions.
name: Test
on: push
jobs:
phpunit:
name: PHPUnit
runs-on: ubuntu-latest
strategy:
matrix:
php: ['7.0', '7.1', '7.2', '7.3', '7.4']
services:
mysql:
image: mysql:5.7
env:
MYSQL_ROOT_PASSWORD: root
MYSQL_DATABASE: wordpress_test
ports:
- 3306
options: --health-cmd="mysqladmin ping" --health-interval=10s --health-timeout=5s --health-retries=3
steps:
- name: Checkout
uses: actions/checkout@v2
- name: Install Composer dependencies
run: composer install -o --no-progress
- name: Setup PHP
uses: shivammathur/setup-php@v1
with:
php-version: ${{ matrix.php }}
extensions: dom, curl, libxml, mbstring, zip, pcntl, pdo, sqlite, pdo_sqlite, mysql, mysqli, pdo_mysql, bcmath, soap, intl, gd, exif, iconv, imagick
coverage: none
- name: PHPUnit
run: |
bin/install-wp-tests.sh wordpress_test root root 127.0.0.1:${{ job.services.mysql.ports['3306'] }} latest true
vendor/bin/phpunitA couple of things to keep in mind:
MYSQL_DATABASEenv variable will setup the database on startup- You have to install Composer dependencies before setting the PHP version or extract the build process to a separate job. Otherwise, make sure the Composer will install or add
--ignore-platform-reqs - You have to connect to MySQL at
127.0.0.1insteadlocalhost. Otherways it may try to connect via socket, which won’t be available - GitHub randomly assigns the external port for services, access it with
${{ job.services.mysql.ports['3306'] }}
Thanks for the post, but I am getting this error on GitHub, not sure yet why:
“The workflow is not valid. The workflow must contain at least one job with no dependencies.”
I fixed commenting the `needs: build` line. But then I got a different error on PHPUnit: `vendor/bin/phpunit: No such file or directory`. That’s because this line tells composer to run on production mode ignoring dev dependencies, but the problem is that phpunit is a “dev” dependency, rendering to not being installed. To fix it, I changed the composer line to: `composer install -o –no-progress`.
Please note that having phpunit as a production dependency and sending it to WP’s directory leads to a huge security vulnerability, as it contains files that allow remote execution. Not saying is the case here, just a heads up to readers.
Thank you Daniel, you are right in both cases and I just updated the code block.
Do you maybe also have a sample plugin where this is all been setup correctly. I’m trying to get a head start reviving my old svrooij/rest-api-filter-fields plugin on github. Going forward and adding automated tests seems like a good thing to do.
Sure, we’ve been using it with our Notification plugin, see the action log.
Hello,
I’m trying to implement tests and I’m stuck with:
“`
Warning: arning] Using a password on the command line interface can be insecure.
ERROR 2003 (HY000): Can’t connect to MySQL server on ‘localhost:3306’ (111)

Check that mysqld is running on localhost and that the port is 3306.
You can check this by doing ‘telnet localhost 3306’

Do you have any idea to help me solving this?
Thank you.
