$expected parameter in test is badly named

Problem/Motivation

The param says:

   * @param array $expected
   *   The expected terms.

But it's not the EXACT list of expected terms, because it's asserted like this:

    foreach ($expected as $term) {
      $this->assertContains($term, $termsInNode);
    }

In other words, if I omit something from this parameter, and it's in the actual value, the test will pass.
