Usage

You need to tell RuboCop to load the RSpec extension. There are three ways to do this:

RuboCop configuration file

Put this into your .rubocop.yml.

require: rubocop-rspec

Now you can run rubocop and it will automatically load the RuboCop RSpec cops together with the standard cops.

Command line

$ rubocop --require rubocop-rspec

Rake task

RuboCop::RakeTask.new do |task|
  task.requires << 'rubocop-rspec'
end

Code Climate

rubocop-rspec is available on Code Climate as part of the rubocop engine. Learn More.

Inspecting files that don’t end with `_spec.rb`

By default, rubocop-rspec only inspects code within paths ending in _spec.rb or including spec/. You can override this setting in your config file by specifying one or more patterns:

# Inspect all files
AllCops:
  RSpec:
    Patterns:
    - '.+'

# Inspect only files ending with `_test.rb`
AllCops:
  RSpec:
    Patterns:
    - '_test.rb$'
