WordPress Testing: Check if plugin activation has successfully created custom tables

Question

first of all, my plugin works on wordpress (it's currently running on production) and creates the DB tables as expected. I recently just started implementing tests and I have the following problem now:

I have set up the testing environment according to the official wordpress documentation. I can execute phpunit and run the example test provided by wordpress without any errors.

I would now like to test the activation of my plugin and also whether the tables that are normally created during activation are available. (I have a connection the testing db.)

public function testPluginActivation(): void
{
    do_action('activate_' . static::PLUGIN_BASENAME);
}

My problems:

• I am not sure if the code above actually simulates a correct activation.
• I don't know how to prove if the tables are being created. (If I take a look at the testing db after running the tests, the tables are not there, only the default ones created by WP at the beginning, but I am not sure if WP kinda does a rollback after all tests.)
