Creating/Running Tests
---
We use PHPUnit and the WordPress test suite for our unit/integration tests.

1. You can install the WordPress test suite [using the installer](https://github.com/CMB2/CMB2/blob/develop/tests/bin/install-wp-tests.sh#L3): `bash tests/bin/install-wp-tests.sh wordpress_test root ''`. (this will install the test suite in the temp folder on your computer, using a test database with those given credentials)
1. Install PHPUnit via composer, `composer install`.
1. Once Composer and the WordPress test sutie are installed, you can run phpunit via `./vendor/bin/phpunit` in the CMB2 directory.
