Compare with:

run_generator(args = default_arguments, config = {})

Runs the generator configured for this class. The first argument is an array like command line arguments:

class AppGeneratorTest < Rails::Generators::TestCase
  tests AppGenerator
  destination File.expand_path("../tmp", __dir__)
  setup :prepare_destination

  test "database.yml is not created when skipping Active Record" do
    run_generator %w(myapp --skip-active-record)
    assert_no_file "config/database.yml"
  end
end

You can provide a configuration hash as second argument. This method returns the output printed by the generator.

Parameters

args opt = default_arguments
config opt = {}
