Create Test Class in IntelliJ

Use the menu selection Navigate -> Test, or Ctrl+Shift+T (Shift+⌘+T on Mac). This will go to the existing test class, or offer to generate it for you through a little wizard.

*IntelliJ 13 * (its paid for) We found you have to have the cursor in the actual class before ctrl+Shift+T worked.

Which seems a bit restrictive if its the only way to generate a test class. Although in retrospect it would force developers to create a test class when they write a functional class.

Alternatively you could also position the cursor onto the class name and press alt+enter (Show intention actions and quick fixes). It will suggest to Create Test.

At least works in IDEA version 12.
