Simulate a click on span tag in enzyme
<p>I have a span tag in my component and I need to click it using enzyme</p>

<pre><code>    &lt;span className="lock"&gt; 
    &lt;span onClick={[undefined]} id="lock"&gt;
    &lt;i className="fa fa-lock" /&gt;
    Reserve this chat
    &lt;/span&gt;
    &lt;/span&gt;
</code></pre>

<p>Here is my test</p>

<pre><code>it('simulating reservechat click ...',()=&gt;{
const wrapper=shallow(&lt;ReserveChat activeConversation={conversation1} /&gt;);
const button=wrapper.find('span').last();
button.simulate('click');
});
</code></pre>

<p>I am confused to find what to click,usually there will be some div class or other findable tags</p>
