Test drupal_get_filename() in the context of a full Drupal installation.

Code

public function testRecursiveRebuilds() {
    // Ensure that the drupal_get_filename() call due to a missing module does
    // not break the data returned by an attempted recursive rebuild. The code
    // path which is tested is as follows:
    // - Call drupal_get_schema().
    // - Within a hook_schema() implementation, trigger a drupal_get_filename()
    //   search for a nonexistent module.
    // - In the watchdog() call that results from that, trigger
    //   drupal_get_schema() again.
    // Without some kind of recursion protection, this could cause the second
    // drupal_get_schema() call to return incomplete results. This test ensures
    // that does not happen.
