The ng:class
allows you to set CSS class on HTML element
conditionally.
<input type="button" value="set" ng:click="myVar='ng-input-indicator-wait'"> <input type="button" value="clear" ng:click="myVar=''"> <br> <span ng:class="myVar">Sample Text </span>
it('should check ng:class', function(){ expect(element('.doc-example-live span').attr('className')).not(). toMatch(/ng-input-indicator-wait/); using('.doc-example-live').element(':button:first').click(); expect(element('.doc-example-live span').attr('className')). toMatch(/ng-input-indicator-wait/); using('.doc-example-live').element(':button:last').click(); expect(element('.doc-example-live span').attr('className')).not(). toMatch(/ng-input-indicator-wait/); });
