There is a minor bug in the selenium plugin for Grails. It has been discussed on the mailing list, but I thought I would also document it here. I’m using Grails 1.0.3 with version 0.4 of the selenium plugin, which wraps selenium core version 0.8.3.
If you install the plugin and try to run the new Grails tasks (create-selenium-test
, create-selenium-domain-test
, or run-selenium
), the system fails with the error
Could not execute method appContext
No such property: appContext for class: ...
It turns out that the way the appContext
variable is handled in Grails has changed, and the plugin hasn’t yet updated to accommodate it.
The recommended fix is to go into the “plugins/selenium-0.4/scripts” directory in your Grails project, and replace ${appContext}
with ${grailsAppName}
in all the Groovy scripts.
If you use the Selenium IDE in Firefox to write your tests, then the fix doesn’t matter until you try to use the run-selenium target. Still, might as well fix it everywhere. This came up on the mailing list back in July, so I assume an updated plugin will be available as soon as the author gets around to it.
I also find that adding the path to firefox.exe to my system path (default is “c:\Program Files\Mozilla Firefox” — don’t you hate Windows paths with spaces??) makes it easier to run the test suite.
Incidentally, unlike Canoo Web Test, you have to make sure your web app is running before executing the test suite. Selenium fires up the browser and puts it through the proper sequence, so the app has to be running first.
I’ve decided that rather than choosing between Selenium and WebTest, I actually like using both. The Selenium IDE in Firefox is really slick and easy to use, while the output reports in WebTest are gorgeous.
