How to get HtmlUnit WebClient to speed up javascript execution to run window.setTimeout?

Question

I am using the HtmlUnit Java library to create a set of regression tests for a web application.

I have an "onload" handler hooked in the body of the application pages to redirect to the timeout page after the session expires. A handler is some kind of JavaScript form:

window.setTimeout( function() { window.location = 'timout.html'; }, 3600000);

I would like to verify that the redirect will eventually start when the time comes, but the closest thing I can find is actually to wait for the entire duration of the time (for example, an hour in the example above), as suggested by the Java sample below:

WebClient webClient = new WebClient(); ... webClient.waitForBackgroundJavaScript( 3600000);

I would like to know if it is possible to fool the script execution mechanism to behave as if a lot of time had passed, without having to wait for minutes or hours of "real time" to run the test suite.

Ideally, you can say that the engine / client / interpreter skipped X milliseconds (to mimic the expectation) or, perhaps, set some kind of “time dilation” factor and poll the page to see how it refreshes.

Answer 1

I do not think you can do this easily. The only way I can see this is to mock the Rhino method, which handles the setup in tests ... Maybe with a card like Mockito ... But that's not what you want, as if you wanted to test page redirection efficiency, you check the amount of time it takes to redirect.
