Michael,
We have the majority of our application being tested by Canoo, with all Groovy based tests. Some of the pitfalls have to do with there being little documentation around Groovy usage in the Canoo documentation. At times, it has been trial and error translating the XML-based documentation to the Groovy implementation. Also, it has been frustrating the way the Canoo plugin for Grails runs the Canoo tests. Overall, though, Groovy has allowed us to write a very robust test suite with very little code duplication, and keep our tests clean. We have had some challenges with controlling the order our tests within a test suite run, and have not been successful with any of the suggestions provided to us to date. It seems to have to do with the way the tests are run as part of Grails test-app. In addition, the tendancy of the plugin to report that tests succeed after they hit a runtime exception and actually fail (rather than failing a test step per se) is troubling. I have made some minor modifications to the plugin to attempt to address some of our issues, but not these ones, yet. I'd love to see the Grails plugin updated as well, as it is now more than a year old. Erica Wieland SRA International Inc.
