Focus on specific specs in RSpec

spec_helper.rb

# add this to your spec helper
RSpec.configure do |config|
  config.treat_symbols_as_metadata_keys_with_true_values = true
  config.filter_run :focus => true
  config.run_all_when_everything_filtered = true
end

# and then use the :focus tag in your specs

it "does something awesome", :focus do
  # only this one will run
end
