Feature: mock with flexmock As an RSpec user who prefers flexmock I want to be able to use flexmock without rspec mocks interfering Scenario: Mock with flexmock Given a file named "flexmock_example_spec.rb" with: """ Spec::Runner.configure do |config| config.mock_with :flexmock end describe "plugging in flexmock" do it "allows flexmock to be used" do target = Object.new flexmock(target).should_receive(:foo).once target.foo end it "does not include rspec mocks" do Spec.const_defined?(:Mocks).should be_false end end """ When I run "spec flexmock_example_spec.rb" Then the exit code should be 0 And the stdout should include "2 examples, 0 failures"
