To run all features you can run:

  rake features

To run specific features you can do something like:

  script/cucumber --require features/steps features/path/to/my.feature

If you want to run a particular scenario find out the line number of
the first Given and run:

  script/cucumber --line 41 --require features/steps features/path/to/my.feature
