Call to undefined method AcceptanceTester::amOnPage
<p>I have a generated class:</p>

<pre><code>&lt;?php

class DefaultCest
{
    public function _before(AcceptanceTester $I)
    {
    }

    public function _after(AcceptanceTester $I)
    {
    }

    // tests
    public function tryToTest(AcceptanceTester $I)
    {
        $I-&gt;amOnPage('/');
    }
}
</code></pre>

<p>and I added method </p>

<pre><code>$I-&gt;amOnPage('/')
</code></pre>

<p>as shown in the examples in documentation.</p>

<p>But this method does not exist. I do not get why? Php storm autocompletes only </p>

<pre><code>am() 
</code></pre>

<p>and </p>

<pre><code>amGoingTo()
</code></pre>

<p>methods when I type </p>

<pre><code>$I-&gt;am
</code></pre>

<p>And of course I am getting that error.</p>

<p>What can be wrong there, why there is no method amOnPage() ?</p>

<p><strong>Update:</strong></p>

<p>acceptance.suite.yml</p>
