Gomega Matchers for Counterfeiter

This package provides some helpful Gomega matchers that help you write effective assertions against counterfeiter fakes.

HaveReceived()

Verifies that a function was invoked on a counterfeiter fake.

e.g.:

myFake := new(FakeSomething)
myFake.Something("arg1", 0)
Expect(myFake).To(HaveReceived("Something").With(Equal("arg1")).AndWith(BeEquivalentTo(0)))

This actually works with any object that implements an "invocation recording" interface.

type Recorder interface{
  Invocations() map[string][][]interface{}
}

Implemented Features

• one not need to specify a gomega matcher to check equality
  • e.g.: these are equivalent:
  • Expect(myFake).To(HaveReceived("Something").With(Equal("arg1"), Equal(0)))
  • Expect(myFake).To(HaveReceived("Something").With("arg1", 0))

Planned Features

(These would be good for new contributors)

• I should be able to specify multiple arguments at once
  • e.g.: Expect(myFake).To(HaveReceived("Something").With(Equal("my-arg", Equal(0)))
• I should be able to specify a number of times a function was invoked
  • e.g.: Expect(myFake).To(HaveReceived("Something").Times(1))
