rspec / guard运行minitest并获得无效选项：-f

Question

I'm running rails 4.1 and when I run rspec inside of guard, it give me the following error at the end:

invalid option: -f

minitest options:
    -h, --help                       Display this help.
    -s, --seed SEED                  Sets random seed
    -v, --verbose                    Verbose. Show progress processing files.
    -n, --name PATTERN               Filter run on /pattern/ or string.

Known extensions: pride
    -p, --pride                      Pride. Show your testing pride!

This is a minitest error, but as far as I can find, I'm not running minitest anywhere. Any idea where this might come from?

spec_helper

require 'rubygems'

ENV["RAILS_ENV"] ||= 'test'
require File.expand_path("../../config/environment", __FILE__)

require 'rails/test_help'

Dir[Rails.root.join("spec/support/**/*.rb")].each { |f| require f }
ActiveRecord::Migration.check_pending! if defined?(ActiveRecord::Migration)
Monban.test_mode!

RSpec.configure do |config|
  config.fixture_path = "#{::Rails.root}/spec/fixtures"

  config.include FactoryGirl::Syntax::Methods
  config.include Monban::Test::Helpers, type: :feature
  config.include Monban::Test::ControllerHelpers, type: :controller
  config.use_transactional_fixtures = true

  config.order = "random"

  config.before :each do
    DatabaseCleaner.strategy = :transaction
    DatabaseCleaner.start
  end

  config.after(:each) do
    DatabaseCleaner.clean

  config.after :each do

end

Answer 1

Turns out, I was running minitest because of this line in my spec_helper :

require 'rails/test_help'

Removing that makes it not run minitest. However, I added that line to keep my test schema up to date with my development schema, a new feature in Rails 4.1. What I should have done is removed this line from my spec_helper :

ActiveRecord::Migration.check_pending! if defined?(ActiveRecord::Migration)

and replaced it with this:

ActiveRecord::Migration.maintain_test_schema!

This seems to be the rspec equivalent to the minitest line that I removed. I found this in the rspec generators here: https://github.com/rspec/rspec-rails/blob/aa5c5f76a9ae847648f48e0ea7802b8e83c11d0f/lib/generators/rspec/install/templates/spec/spec_helper.rb.tt#L15-L23

Now my schema stays up to date and minitest doesn't run.

Had the same issue. For me, removing test-unit gem fixed it.

Some other gems can cause this as well: https://github.com/guard/guard-rspec/issues/169
