Cucumber not identifying steps definition

Question

I have written a feature and a step definition. However, cucumber is not identifying the step definition.

my_first.feature

Feature:
  As an iOS developer
  I want to have a sample feature file
  So I can see what my next step is in the wonderful world of Frank/Cucumber testing

Scenario: 
    Launching the app

Given I launch the app

The step definition file is in step_definitions folder and is named as launch_steps.rb. The code is :

def app_path
  ENV['APP_BUNDLE_PATH'] || (defined?(APP_BUNDLE_PATH) && APP_BUNDLE_PATH)
end

Given /^I launch the app$/ do
  launch_app app_path
end

However, when I run cucumber in terminal, I do not get proper output. Following is the log from terminal

features git:(frank) ✗ cucumber my_first.feature
/System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/2.0.0/universal-darwin13/rbconfig.rb:212: warning: Insecure world writable dir /usr/local in PATH, mode 040777
Feature: 
  As an iOS developer
  I want to have a sample feature file
  So I can see what my next step is in the wonderful world of Frank/Cucumber testing

  Scenario:                # my_first.feature:6
      Launching the app
    Given I launch the app # my_first.feature:9

You can implement step definitions for undefined steps with these snippets:

Given(/^I launch the app$/) do
  pending # express the regexp above with the code you wish you had
end

If you want snippets in a different programming language,
just make sure a file with the appropriate file extension
exists where cucumber looks for step definitions.

I am trying to learn cucumber and as first feature, I am trying to launch the app. Thus, my expectation is that app would launch with this feature.

PS: I have not executed app from XCode.

Answer 1

I have found the answer. We need to run this from a level up in directory.

Answer 2

You should try and see the first option of cucumber help with

 bundle exec cucumber --help

-r, --require LIBRARY|DIR        Require files before executing the features. If this
                                 option is not specified, all *.rb files that are
                                 siblings or below the features will be loaded auto-
                                 matically. Automatic loading is disabled when this
                                 option is specified, and all loading becomes explicit.
                                 Files under directories named "support" are always
                                 loaded first.
                                 This option can be specified multiple times.

And then you can run:

bundle exec cucumber features/my_first.feature -r features/
