WordPress UnitTest tools

This project serves as command line to enable the download of the WordPress Unittests helper functions and setup the environment for executing your plugin Unit Tests
This suite is heavily inspired by the WordPress REST API plugin install-wp-test.sh shell script.
That script was a great source to learn how to unittest WordPress plugins.
