      Use the <code>server</code> script instead:

```
      <br/><br/>
```

      <code>node ./fixtures/devtools/regression/server.js</code><br/>

      <code>open <a href="http://localhost:3000/15.3.html">http://localhost:3000/15.3.html</a></code>

```
    </div>
```

    <script src="shared.js" type="text/babel"></script>
