How to skip the code execution from PhantomJS or g

问题:

The problem is next: I have JavaScript code in my application and I want to skip/hide some peace of code from PhantomJS and grover checking/execution.

So, how can I skip/hide the code execution from PhantomJS or grover?

Note: the problem has occurred when I was writing the JavaScript unit-tests. But I think it would be helpful in other cases.

回答1:

You just need to wrap the code with simple verification:

if (!window['phantom'] && !window['_phantom']) {
  // your code here...
}

In this case the code in your application will be executed as normal but skipped when the PhantomJS or grover will inspect it.

Notes:

• I use "window['phantom']" - because my application is minimized using google closure compiler, in other case you can easily use (!window.phantom && !window._phantom);
• window['_phantom'] - indicates presence PhantomJS using grover tool.
