Golang Action.SetSignature Examples

Example #1

File: return_test.go Project: ebfe/scaleway-cli

func (t *ReturnTest) NoReturnValues() {
	sig := reflect.TypeOf(func() {})
	var a oglemock.Action
	var err error
	var vals []interface{}

	// No values.
	a = oglemock.Return()
	err = a.SetSignature(sig)
	AssertEq(nil, err)

	vals = a.Invoke([]interface{}{})
	ExpectThat(vals, ElementsAre())

	// One value.
	a = oglemock.Return(17)
	err = a.SetSignature(sig)
	ExpectThat(err, Error(HasSubstr("given 1 val")))
	ExpectThat(err, Error(HasSubstr("expected 0")))

	// Two values.
	a = oglemock.Return(17, 19)
	err = a.SetSignature(sig)
	ExpectThat(err, Error(HasSubstr("given 2 vals")))
	ExpectThat(err, Error(HasSubstr("expected 0")))
}

Example #2

File: return_test.go Project: ebfe/scaleway-cli

func (t *ReturnTest) MultipleReturnValues() {
	sig := reflect.TypeOf(func() (int, string) { return 0, "" })
	var a oglemock.Action
	var err error
	var vals []interface{}

	// No values.
	a = oglemock.Return()
	err = a.SetSignature(sig)
	ExpectThat(err, Error(HasSubstr("given 0 vals")))
	ExpectThat(err, Error(HasSubstr("expected 2")))

	// One value.
	a = oglemock.Return(17)
	err = a.SetSignature(sig)
	ExpectThat(err, Error(HasSubstr("given 1 val")))
	ExpectThat(err, Error(HasSubstr("expected 2")))

	// Two values.
	a = oglemock.Return(17, "taco")
	err = a.SetSignature(sig)
	AssertEq(nil, err)

	vals = a.Invoke([]interface{}{})
	ExpectThat(vals, ElementsAre(IdenticalTo(int(17)), "taco"))
