Can I set rspec --format documentation as the default?

Question

Per the Rspec documentation, by default when you run rspec you get the progress formatter (looks like this: ".....").

There is another formatting option rspec --format documentation that goes through each test one by one. My question: how can I enable --format documentation by default without having to type it in the command line every time?

Answer 1

Option 1

Add it to .rspec file (or create one in the project's root directory) - options added to it will be applied to every test run within current project:

# .rspec
--color
--format documentation

Option 2

Add it to RSpec.configure block:

RSpec.configure do |config|
  config.formatter = :documentation
end

Option 3

Specify rspec's options globally by adding them to ~/.rspec.
