13.24Retry test

Suppose production has retry logic.

You want:

attempt 1 → timeout
attempt 2 → timeout
attempt 3 → success

For more dynamic mocks, MUnit supports then-call, where a mock delegates to another flow that can vary its behavior based on state.

Conceptually:

mock flow

if attempt == 1
   error
if attempt == 2
   error
if attempt == 3
   success

Then verify final success.
