I have run into a problem while trying to test a web application with HtmlUnit. Please bear in mind that I haven't used HtmlUnit very long so I might be missing something trivial.
For some reason externally referenced javascripts aren't being loaded. When I print the page as xml all i get is this:
<script language="javascript" src="urltofile.js">
</script>
As you can see the script tag is empty when it should contain the javascript. What am I missing? I have googled for a solution all morning but haven't found any relevant information. Any help would be greatly appreciated!
After many many hours of googling I found the solution to be very simple. All I had to do was to wait a few seconds after the page is retrieved to allow the javascript some time to execute before doing anything else. I can honestly say finding the solution was a bit of an anticlimax, but at least I can move along to more important stuff now. :)
That tag loads an external file: "urltofile.js", so it's not strange to have nothing into because the js code is loaded from that file and not injected into the existing markup.
