fsr - fast spec runner

fsr listens for file change events and runs RSpecs automatically in rails console avoiding the rails boot process and provides instant feedback which is crucial for Test Driven Development (TDD).

1. Add fsr to your app’s Gemfile in test:

   group :test do
     gem 'fsr'
   end

2. Then, in your project directory:

   $ bundle install

Open rails console in test environment.

 RAILS_ENV=test bundle exec rails c

All following examples should be run in this console.

listener = Fsr.listen(['spec/models/user_spec.rb'])
listener.start

This will listen to any file change events, automatically load the changed file and run the given spec.

To stop the listener,

listener.stop

By default, it listens for file change events on app/, lib/, spec/ directories. This can be overriden with listen option.

Fsr.listen(['spec/models/user_spec.rb'], listen: ['dir/'])

You can pass any RSpec command line arguments. For example, to run based on line number.

Fsr.listen(['spec/models/user_spec.rb:12'])

To run based on line number.

Fsr.listen(['spec/models/user_spec.rb', 'spec/models/admin_spec.rb'])
