title: How to test a click event in protractor for an element which do not have id
body: <p>We have build a website which i need to test using Protractor. The site have many elements which do not have any id. So protractor.by.id will not work here. I have the protractor.by.css option but how will I distinguish a unique element if group of element have the same css applied. Please suggest.</p>
  
  <pre><code>&lt;div class="buttons contact_page"&gt; 
  &lt;a href="http://mysite.se/om-oss/" class="btn btn-default button"&gt;Om oss&lt;/a&gt;
  &lt;a href="http://mysite.se/offert-3/" class="btn btn-default button"&gt;Offert&lt;/a&gt; 
  &lt;a href="http://mysite.se/tjanster/" class="btn btn-default button"&gt;Våra Tjänster&lt;/a&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>Thanks
