Using meck to make multiple calls to the same method with the same arguments

I know that with ruby/rspec, you can do something like the following in order to receive different return values for the different calls made to the method:

allow(double).to receive(:msg).and_return(value1, value2, value3)

I've only been able to make meck stub a method with one return value like so:

meck:expect(module, some_method, fun() -> ok end)

Is there a way to make it return ok on the first call and then ok2 on the second?

To do this, there are two shortcuts in Meck you can use:

• meck:sequence/4 This function returns each element in a sequence, until the last element. Then, the last element is returned indefinitely.

  6> meck:sequence(module, some_method, 0, [ok, ok2]).
  ok
  7> module:some_method().
  ok
  8> module:some_method().
  ok2
  9> module:some_method().
  ok2
  

• meck:loop/4 This function returns each element in a loop. When the last element is returned, it starts over with the first.

  10> meck:loop(module, some_method, 0, [ok, ok2]).
  ok
  11> module:some_method().
  ok
  12> module:some_method().
  ok2
  13> module:some_method().
  ok
