click(link("ac-gn-link ac-gn-link-iphone"));       
click(heading4("typography-headline-reduced"));        
var var1=isVisible(heading4("typography-headline-reduced"));       
var val2=;        
alert(var1);       
if (var1==true){      
  click(link("ac-gn-link ac-gn-link-watch"));       
}

Assert
Assert Contains Text
As the name suggests, assert contains text checks for a string in the target element and logs success or failure.
It will log the step details if the assertion passes else it logs as a failure if the expected string or reg-ex is not part of the text content of a given element with a proper explanation and stops the script playback.
Note: Do not use this in an if condition as it does not return any value, and throws an exception if the assertion fails.
The example below and Usage: 
The accessor column shows the HTML DOM Element of the web page.
The value column shows the Expected String, Regular expressions can also be used.
