My EXTJS application has a page with EMail button and on clicking it creates a link to page contents and opens default email client with this link in body.
In the inspect DOM, the EMail button has just this.
<span id="basebutton-1358-btnInnerEl" data-ref="btnInnerEl" unselectable="on" class="x-btn-inner x-btn-inner-basebutton-large">Email</span>
In the entire DOM, there is no 'mailTo'.
All I need to verify here is the link that is generated on click. I don't really concerned about whether it opens up any Email client or not.
