Running Features

Using the Gem’s ‘cucumber’ Command

Assuming you’ve installed cucumber as a gem, run this at a command prompt to see the options for running features:

cucumber --help

For example

cucumber features/authenticate_user.feature --line 44 --format html > features.html

…will run the scenario defined at line 44 of the authenticate_user feature, format it as HTML and pipe it to the features.html file for viewing in a browser.

Using the rake task (in a rails app)

rake features
