How to set timeout on before hook in mocha? : <p>I want to set timeout value on before hook in mocha test cases. I know I can do that by adding <code>-t 10000</code> on the command line of mocha but this will change every test cases timeout value. I want to find a way to change the timeout programmatically below is my code:</p>

<pre><code>describe('test  ', () =&gt; {

  before((done) =&gt; {
        this.timeout(10000);
         ...
</code></pre>

<p>it will complain about the line <code>this.timeout(1000)</code> that <code>timeout</code> is not defined. How to set the timeout on before hook.</p>
