How to run a single RSpec test?

Question

I have the following file:

/spec/controllers/groups_controller_spec.rb

What command in terminal do I use to run just that spec and in what

Answer 1

Run the commands from your project's root directory:

# run all specs in the project's spec folder
bundle exec rspec 

# run specs nested under a directory, like controllers
bundle exec rspec spec/controllers

# run a single test file
bundle exec rspec spec/controllers/groups_controller_spec.rb

# run a test or subset of tests within a file
# e.g., if the 'it', 'describe', or 'context' block you wish to test
# starts at line 45, run:
bundle exec rspec spec/controllers/groups_controller_spec.rb:45
