What to do if you get a Call with too many input arguments error at DoAndReturn in a golang test

m.EXPECT().SomeMethod(name string, number int).DoAndReturn(func() error {
  //Various processing
  return nil
})

This gives a panic: reflect: Call with too many input arguments error

So do the following

m.EXPECT().SomeMethod(name string, number int).DoAndReturn(func(name string, number int) error {
  //Various processing
  return nil
})

In other words, the argument of the method (SomeMethod) you want to mock and the argument of the function of DoAndReturn must match.
