How do you mock an object to expect A then B then A?

Testing RSpec

Hi Folks,

I want to assert on an order of interaction between two objects where
one
method gets repeated.

Here is a simple example…

this fails "Mock ‘x’ expected :a with (any args) once, but received it

twice"

x = mock(“x”)
x.should_receive(:a).once.ordered
x.should_receive(:b).once.ordered
x.should_receive(:a).once.ordered

x.a
x.b
x.a

Am I setting up the ordered expectations incorrectly, or is this a bug?

Cheers
Nigel

Could be wrong, but what about removing the stipulation that each call
should be received once?
Is that superfluous to requirements, there? I think so.
You’ve already specified three calls in order, so that should cover it.

In my case I need to specify this behaviour. (I’m making sure the
logging
happens in the right order).

I believe it really is a bug, so I have forked rspec (on github),
written a
failing test and fixed my version of rspec to handle this case.

My version now matches against unsatisfied expectations in preference to
satisfied ones.

I’m not sure what the next step is in contributing a patch back…I guess
I
raise a ticket in lighthouse.

Me either, but I salute your go-to attitude & community-mindedness!
