To navigate from a .feature file to step definition
  1. Open the desired .feature file in the editor.
  2. Do one of the following:
    • Keeping the ^ button pressed, hover your mouse pointer over a step. The step turns to a hyperlink, and its reference information is displayed at the tooltip:

      ../../Shared/cucumberJumpToStepDefinition.png

      Click the hyperlink. The step definition file opens in the editor, with the caret resting at the desired step definition.

    • On the main menu, choose Navigate | Declaration.
    • Press ⌘B⌘BF3F12^ ⌥ G.

You cannot navigate to a step definition file, if it resides outside a package under the test root.
