body: <p>I m writing a night watch js e-t-e test for my site. My site has a right hand tabs that are use as a menu that allow user to navigate. Te problem is my niightwatch is not able to perform click on the tab. I tried everything possible to no avail. </p>
  
  <pre><code>.verify.elementPresent('div[role="tab"][title="Asset Index"]')
  .click('#right-tab-list div:nth-child(5)', function(status){
          console.log('the click status is', status.status);
          browser.click('#right-tab-list div:nth-child(5)');
  })
  .waitForElementVisible('div[role="tab"][aria-selected="true"][title="Asset Index"]', 3000)
  </code></pre>
  
  <p>.verifying <code>div[role="tab"][title="Asset Index"]</code> present returns positive.  However, the click on the <code>div:nth-child(5)</code> of the <code>#right-tab-list</code> failed. The 5th child is the <code>div[role="tab"][title="Asset Index"]</code> . The click status returns -1.Before i my code was </p>
  
  <pre><code>.verify.elementPresent('div[role="tab"][title="Asset Index"]')
  .click('div[role="tab"][title="Asset Index"]', function(status){
         console.log('the click status is', status.status);
         browser.click('#right-tab-list div:nth-child(5)');
   })
   .waitForElementVisible('div[role="tab"][aria-selected="true"][title="Asset Index"]', 3000)
  </code></pre>
  
  <p>verifying the element present returns true . However the click status returns negative . The proceeding <code>waitForElementVisible</code> failed as well. I tried everything possible to no aveil. It was working 4 months back though. I just am not sure why not today. Any help would be appreciated.</p>
