Debugging Javascript in HtmlUnit

[Bob Silverberg]

I'm looking into adding the color standardization behaviour [1] into the HtmlUnit driver which was done for the atoms.  Tracing through the test at [2], it seems that the Javascript that is executed (which is defined at [3]) is returning null. To me this says that I need to start debugging the js itself and I'm not sure how to do that.

With any other browser I'd just open the browser and start debugging, but I'm not sure how to do that with HtmlUnit. I assume that there's a way of debugging js running in HtmlUnit, and I'm hoping someone can steer me in the right direction.

Thanks for any help you can provide,
Bob

In my experience, you don't.  HtmlUnit strips out the few hooks Rhino has for debugging.  There might be a global "print" function (I don't remember if console exists).

For HtmlUnit, I would just pull the color out and do all your parsing in Java.

Thanks Jason. It turns out there was something strange going on in my
test, as when I tested again today I am no longer getting null
returned, but rather the expected color value.

I have another question specific to color conversion for htmlunit
which I am going to post separately.

Hi,

if you have access to the underlying WebClient, you can call

com.gargoylesoftware.htmlunit.util.WebClientUtils.attachVisualDebugger(webClient)

this will start Rhino's visual debugger.

In fact the JS code in HtmlUnitWebElement could/should probably better
be replaced by direct calls to HtmlUnit's Java methods.

Cheers,
Marc.
