How to reset the headless test db?

Question

I'm using headless phpunit tests. I noticed that the first time I do this it pauses and says about installing schema for xxxx - a test database.

If you break stuff enough, you can end up with a corrupted/no-good test CRM database. How do you get a fresh one back?

I tried dropping the test database, but that just caused errors.

Thanks.

ah-ha!

In your test class edit the setUpHeadless() method which might look at first like this:

  public function setUpHeadless() {                                                                                                                                                                                                           
    // Civi\Test has many helpers, like install(), uninstall(), sql(), and sqlFile().
    // See: https://github.com/civicrm/org.civicrm.testapalooza/blob/master/civi-test.md
    return \Civi\Test::headless()
      ->installMe(__DIR__)
      ->apply();

But pass TRUE to apply(), ie

  public function setUpHeadless() {                                                                                                                                                                                                           
    // Civi\Test has many helpers, like install(), uninstall(), sql(), and sqlFile().
    // See: https://github.com/civicrm/org.civicrm.testapalooza/blob/master/civi-test.md
    return \Civi\Test::headless()
      ->installMe(__DIR__)
      ->apply(TRUE);

Ta-daa! And now your tests will run super slow as the schema will be reinstalled every time. But helps you out of a spot, and you can of course remove that param.

It's also worth noting that if you're using civicrm-buildkit to create your test sites (highly recommended) you can also rebuild a site with civibuild reinstall.
