This PR adds the binary compatibility tests for the client protocol.

We test the behaviour of the client and member separately.

For the client side, we do the following on the tests:

For each codec

  • We encode the request using the codec and compare the client message generated with it to the client message generated by the protocol binary test generator.

  • We decode the response using the codec from the client message generated by the protocol binary test generator. After decoding it, we compare each parameter of the response with the predefined reference objects.

  • If there are any events related to codec, we pass the client message generated by the protocol binary test generator to the event handler class and compare the parameters of the event with the predefined reference objects.

For the member side, we do the reverse of the things we have done for the client side. Namely, we decode the request, encode the response and encode the event and compare them to the contents of the binary file as described above.

Also, there are two separate tests where we use null values in the nullable parameters.

See the templates on the protocol repo for the details of the client message comparison.
