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

With Rake:

rake spec SPEC=path/to/spec.rb

(Credit goes to this answer. Go vote him up.)

EDIT (thanks to @cirosantilli): To run one specific scenario within the spec, you have to supply a regex pattern match that matches the description.

rake spec SPEC=path/to/spec.rb \
          SPEC_OPTS="-e \"should be successful and return 3 items\""

Answer 2

For model, it will run case on line number 5 only

bundle exec rspec spec/models/user_spec.rb:5

For controller : it will run case on line number 5 only

bundle exec rspec spec/controllers/users_controller_spec.rb:5

For signal model or controller remove line number from above

To run case on all models

bundle exec rspec spec/models

To run case on all controller

bundle exec rspec spec/controllers

To run all cases

 bundle exec rspec

@apneadiving answer is a neat way of solving this. However, now we have a new method in Rspec 3.3. We can simply run rspec spec/unit/baseball_spec.rb[#context:#it] instead of using a line number. Taken from here:

RSpec 3.3 introduces a new way to identify examples[...]

For example, this command:

$ rspec spec/unit/baseball_spec.rb[1:2,1:4] …would run the 2nd and 4th example or group defined under the 1st top-level group defined in spec/unit/baseball_spec.rb.

So instead of doing rspec spec/unit/baseball_spec.rb:42 where it (test in line 42) is the first test, we can simply do rspec spec/unit/baseball_spec.rb[1:1] or rspec spec/unit/baseball_spec.rb[1:1:1] depending on how nested the test case is.

Answer 4

You can do something like this:

 rspec/spec/features/controller/spec_file_name.rb
 rspec/spec/features/controller_name.rb         #run all the specs in this controller

Answer 5

starting with rspec 2 you can use the following:

# in spec/spec_helper.rb
RSpec.configure do |config|
  config.filter_run :focus => true
  config.run_all_when_everything_filtered = true
end

# in spec/any_spec.rb
describe "something" do
  it "does something", :focus => true do
    # ....
  end
end

Answer 6

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
