Take a look at the WordPress core setup with PHPUnit: https://make.wordpress.org/core/handbook/testing/automated-testing/phpunit/ Using this process rather than rolling your own allows you to leverage the boostrapping (and other customization) specific for WordPress.

What you have discovered is that WordPress is loaded—and all of the actions are called—before the tests run. It is possible to hook into an action when WordPress is loaded, but it has to be done from your PHPUnit bootstrap file instead of from the testcase class. I don’t know what your bootstrap file looks … Read more
