Sometimes I find that I want to debug a JsUnit test because I’m not quite sure what’s going on in the browser. FireBug has a nice debugger, but I couldn’t get it to work with the JsUnit test runner. I could set breakpoints in JsUnit itself, but any breakpoints in my test would be ignored. And then it hit me: ditch the test runner.

Recently, I was trying to pass some info from my Javascript into my XSL stylesheet. Here’s how I finally did it.

I was playing with a very JavaScript-heavy web page and wanted my automated tests to use a real web browser. I tried running them inside Safari, but it’s a bit annoying to have my tests take control of my browser. Plus, there were caching issues. So I wrote a very simple web browser.

Google has written an open-source library called Ajaxslt that implements XPath and XSLT in Javascript. It took a bit of playing to get it to work.
