phpunit-testing

Run PHPUnit tests with a bootstrap script that mocks WordPress and ACF functions, validating block helpers and render templates without a live database. Use composer test to execute the suite and verify PHP code quality safely.

Mocking ACF functions in PHP unit tests is handled by a bootstrap script with mock implementations in references/bootstrap.php. This isolates your theme code, validating data providers and render templates against expected return values.

Yes, you need Composer to run unit tests for WordPress block helpers using the composer test command. The testing framework also requires PHPUnit installed and organized test files under tests/php to execute regression checks.

Yes, you can test PHP render templates and data providers safely by running mock-based PHPUnit tests. This approach validates behavior across common scenarios and edge cases, facilitating safe refactors without breaking WordPress or ACF integrations.

PHPUnit tests fail when calling WordPress core functions if the bootstrap script does not properly mock them. Ensure references/bootstrap.php contains the necessary mock implementations for WP and ACF functions to execute tests under tests/php.

You need mock implementations for WordPress unit testing when validating block helpers and render templates that depend on WP or ACF functions. Mocking isolates the code being tested, enabling safe changes and regression checks across the theme.
