Do you think we are missing an alternative of quickcheck-state-machine-distributed or a related project?
quickcheck-state-machine-distributed is Haskell library for testing stateful,
possibly distributed, programs. It's based on QuickCheck, but differs from the
approach in that it lets the user specify the correctness by means of a state
machine based model using pre- and post-conditions. The advantage of the state
machine approach is twofold: 1) specifying the correctness of your programs
becomes less adhoc, and 2) you get testing for race conditions for free.
The combination of state machine based model specification and property based
testing first appeared in Erlang's proprietary QuickCheck. The
quickcheck-state-machine-distributed library can be seen as an attempt to
provide similar functionality to Haskell's QuickCheck library.
quickcheck-state-machine-distributed library builds upon ideas from the
sister library. The most significant difference is that the former is based on
distributed-process library, hence the name. A more detailed comparison
for a full example of how to implement and test a ticket dispenser -- think of
one of those machines in the pharmacy which gives you a piece of paper with your
number in line on it.
Apart from the already mentioned difference that
-distributed is based on
distributed-processes, it's also different in that it:
Decouples requests from responses (opening up the possibility for testing asynchronous interfaces);
Takes a more lightweight approach; no GADTs, no references (which hopefully makes the library easier to understand and use).
quickcheck-state-machine-distributed library is still very experimental.
We would like to encourage users to try it out, and join the discussion of how we can improve it on the issue tracker!
