title: Grails 3.3.8 : Unable to resolve ControllerUnitTest
body: <p>I am attempting to write some basic controller tests and am following the documentation <a href="https://docs.grails.org/latest/guide/testing.html" rel="nofollow noreferrer">https://docs.grails.org/latest/guide/testing.html</a>. My test currently is unable to find <strong>ControllerUnitTest</strong>. Is there a dependency that I am missing?</p>
  
  <p>Here is my import</p>
  
  <pre><code>grails.testing.web.controllers.ControllerUnitTest
  </code></pre>
