title: Does chai assertion library return true/false on passed/failed step?
body: <p>I am using webdriverio with chai assertion library for UItesting, while asserting a string i was wondering if I can make chai to return true/false when the assert passed or failed depending on the step. </p>
  
  <pre><code>var text = "some test";
  var result = assert(text === "some test");
  console.log(result);
  </code></pre>
  
  <p>The output from the above code is <code>undefined</code> </p>
  
  <p>Is there a way I can make it return <code>true</code> or <code>false</code>? or is there another library that I could use which supports this action. </p>
  
  <p>Thanks</p>
