One of the interesting things about Google Wave is that it was implemented using the Google Web Toolkit (GWT, pronounced ‘gwit’ apparently). GWT is a Java-based framework that compiles your code to HTML/JS/CSS. Like a lot of folks, I was skeptical about this idea (particularly since none of the significant Google web services were built using GWT). The fact that Google has implemented a major service on top of this toolkit now gives me a sense that GWT has been put through its paces.

Anyway, after the announcement, I adjusted my second day conference schedule so that I could take in the session on Wave and GWT. As part of this talk, they mentioned how they use WebDriver to automate testing of Wave across browsers. I had never really heard about automating web app testing, so I found the notion particularly interesting. Has anybody had any success with Selenium or WebDriver on apps that use SVG or Canvas?

Really briefly I tried to use the Selenium IDE extension for Firefox to run a test on the svg-edit demo. Unfortunately it doesn’t seem possible to capture the mouse click/movement on SVG elements, which means it’s a non-starter for me at the moment. I signed up for an account with OpenQA and asked an unanswered question. Note that after I asked this question, the svg-edit app abandoned its use of the <object> tag in favor of inline SVG that is programmatically added to the page. Unfortunately this resulted in the same effect: Selenium IDE ignores mouse clicks within SVG elements. Bummer.

I then tried to submit a bug only to find that OpenQA’s JIRA was crashing. To report THAT bug I’d have to sign up with an account at atlassian and that’s just too many degrees away from where I want to be. No one was around on the #selenium channel in IRC Freenode so I gave up for now. Hot Tip: if you want to build a community, make sure basic things like signing in to your bug tracker work!
