A complete example for using WP PHPUnit in the context of plugin development.

Travis CI Configuration

A ready to use .travis.yml configured with a reasonable test matrix

• Includes all currently supported versions of PHP (7.4 and 8.0) and the current WP minimum required PHP 5.6
• Tests against the latest version of WordPress, as well as an older version (4.9) although it could be easily extended to include multiple older versions, multisite, etc.

Just Add Tests

This project includes a working example test-example.php test case. Adding tests is as simple as adding methods to this example class! Getting up and running couldn't be easier.

Install Composer dependencies

$ composer install

Create a database for your tests to use and update your tests/wp-config.php as necessary.

$ mysqladmin create wp_phpunit_tests -u root

The database name defaults to wp_phpunit_tests, but you can change this in the tests/wp-config.php without affecting the Travis configuration which is environment variable-based.

Run the tests

$ composer test
