We’ve added a couple of new productivity features in IntelliJ IDEA 10.5 to make working with Groovy tests two bits more pleasant:
1. Now you can create tests for Groovy classes the same way you do in Java. You just need to invoke Create Test intention on the header of the class.
2. To navigate to an existing test from a class you can invoke Go to Test action (Ctrl+Shift+T by default).
Make sure to try it in the latest IntelliJ IDEA 10.5 EAP build.
