  <p>The test itself seems to be ok, but I get the error nevertheless.</p>
  
  <p>I tried different solutions:</p>
  
  <p>-Some people say it would be necessary to add these configs to the package.json:</p>
  
  <pre><code>"jest": {
      "moduleDirectories": [
        "node_modules",
        "src"
      ],
      "moduleFileExtensions": [
        "ts",
        "tsx",
        "js",
        "jsx"
      ]
    }
  </code></pre>
  
  <p>But I had no luck with that either. Can someone help here?</p>
