Monkeypatches to have minitest work with rspec-mocks. Note the name changed from
minitest-rspec_mocks for consistency with the idea that this is a plugin for minitest.
include Minitest::RSpecMocks in whichever test case base classes you want
rspec-mocks to be available. For example, if you're in a Rails project that
uses minitest and you want rspec-mocks everywhere, you might do:
class ActiveSupport::TestCase include Minitest::RSpecMocks end class TestSomething < ActiveSupport::TestCase def test_it_should_use_rspec_stub RSpec::Mocks.configuration.syntax = :should string = "hello" assert string.to_i == 0 string.stub(to_i: 100) assert string.to_i == 100 end def test_it_should_use_rspec_expect RSpec::Mocks.configuration.syntax = :expect string = "hello" assert string.to_i == 0 expect(string).to receive(:to_i).and_return 100 assert string.to_i == 100 end end
Note that you must include it in a base class for your tests. Including it in the test class itself will not work.
Note that RSpec 3 deprecates the
object.should (where you use
object.stub(to_i: 100)) style in favor of using the
expect style syntax.
If you use minitest/autorun, it patches its
stub method onto
Object. RSpec puts its version on
BasicObject so it being further up the ancestor chain, it will rarely be used.
Also there is a little bit of setup / teardown you need to do a la http://myronmars.to/n/dev-blog/2012/07/mixing-and-matching-parts-of-rspec
gem "minitest-rspec_mocks" in your Gemfile
Run the tests:
git clone this repository, then cd into it and run
bundle exec ruby test/minitest/rspec_mocks_test.rb
