Install PHPUnit, WP-CLI phar, and Scaffold Unit Tests for WordPress Plugin

It looks like you have provided instructions for setting up PHPUnit and WP-CLI for WordPress plugin development, along with the steps to scaffold unit tests for your plugin. Additionally, you have included instructions for setting up the ‘wordpress_test’ database for the test suite.

Let me break down the steps:

Install PHPUnit:

  • Download PHPUnit: wget -O phpunit https://phar.phpunit.de/phpunit-10.phar
  • Make it executable: chmod +x phpunit
  • Move it to the bin directory: sudo mv phpunit /usr/local/bin/phpunit
  • Check the installed version: phpunit --version
  • Make sure compatibility of phpunit phar with PHP version.

Install WP-CLI:

  • Download WP-CLI: curl -O https://raw.githubusercontent.com/wp-cli/builds/gh-pages/phar/wp-cli.phar
  • Make it executable: chmod +x wp-cli.phar
  • Move it to the bin directory: sudo mv wp-cli.phar /usr/local/bin/wp

Scaffold Unit Tests for WordPress Plugin:

  • Inside the WordPress directory, scaffold unit tests for your plugin: wp scaffold plugin-tests plugin-name
    (This assumes your plugin is located at /wp-content/plugins/plugin-name)
  • If you don’t have a plugin directory yet, scaffold initial plugin code with unit test code: wp scaffold plugin-name
    (This will create a ‘tests’ directory inside your plugin directory with the necessary files)

Set Up ‘wordpress_test’ Database:

  • Switch to the plugin directory: cd /path/to/your/plugin
  • Run the database setup script, replacing ‘root’ and ‘password’ with your MySQL server credentials:
    bash bash bin/install-wp-tests.sh wordpress_test root password localhost latest

These steps cover installing PHPUnit and WP-CLI, scaffolding unit tests for your WordPress plugin, and setting up the test database. Ensure that you replace placeholder values like ‘plugin-name’, ‘root’, ‘password’, and adjust paths according to your project structure.
