I've never seen such a web-interface... But, as you say you are always using your IDE and your webbrowser, why not think the other way ?
i.e. a possible solution would be to launch the unittests from your IDE ;-)
Which means you should be able to click on the failing tests to "jump" to either the test method, or the reason that caused the test to fail, for instance.
In the PHP + PHPUnit world, I know that Zend Studio does that -- yes, it's not free, unfortunatly ;-(
Using Eclipse PDT, a solution would be to register PHPUnit as an external tool (see or instance this blogpost : Using PHPUnit with Eclipse PDT) -- but it's quite not sexy, and you cannot click on the results to jump the the methods/tests...
Another solution would be to develop a plugin to integrate PHPUnit into Eclipse PDT (like it's been done for Zend Studio, I suppose) -- A phpunit4eclipse was created some time ago, but it's just a start, and didn't get much succes, so the author didn't work on it after releasing that...
