title: TypeError: firebase.loadStorageRules() is not a function
body: <p>I'm writing unit tests for the Firebase Storage security rules and when attempting to run the mocha test I get this error:</p>
  <blockquote>
  <p>TypeError: firebase.loadStorageRules() is not a function</p>
  </blockquote>
  <p>For some reason the functions related specifically to Storage rules are not recognized even though it is in the documentation i'm using:
  <a href="https://firebase.google.com/docs/rules/unit-tests#rut-v1-testing" rel="nofollow noreferrer">https://firebase.google.com/docs/rules/unit-tests#rut-v1-testing</a></p>
  <p>It should be noted that the firstore db rules functions (ex. loadFirestoreRules() )are recognized and those tests do work.</p>
  <p>I'm thinking it must be a dependency issue, and I have tried updating the related packages but it's still not working. I'm using js v8 sdk with the following dependencies:</p>
  <pre><code>&quot;firebase-admin&quot;: &quot;^8.9.2&quot;,
  &quot;firebase-functions&quot;: &quot;^3.3.0&quot;
  &quot;@firebase/testing&quot;: &quot;^0.20.11&quot;
  &quot;firebase-functions-test&quot;: &quot;^0.1.7&quot;
  </code></pre>
