This was enabled by the recent open-sourcing of JSON support and MessageDifferencer. MessageDifferencer allows the conformance suite to expand because it allows us to write tests for payloads that parse successfully. To verify the testee's output payload, we need to parse it back into a message and compare the message instances. Comparing output bytes vs. a golden message is *not* valid, because protobufs do not have a canonical encoding (especially in the presence of maps, which have no prescribed serialization order). We only add one small JSON test for now, but with the framework in place we now have the foundation to dramatically expand the coverage of the conformance test suite. Also added the ability for the testee to skip tests that exercise features that are unimplemented. This allows Java (which currently has no JSON support) to skip tests involving JSON.

Protocol Buffers - Google's data interchange format
Copyright 2008 Google Inc.
This directory contains conformance tests for testing completeness and correctness of Protocol Buffers implementations. These tests are designed to be easy to run against any Protocol Buffers implementation.
This directory contains the tester process conformance-test
, which
contains all of the tests themselves. Then separate programs written
in whatever language you want to test communicate with the tester
program over a pipe.
Before running any of these tests, make sure you run make
in the base
directory to build protoc
, since all the tests depend on it.
$ make
Then to run the tests against the C++ implementation, run:
$ cd conformance && make test_cpp
More tests and languages will be added soon!
Testing other Protocol Buffer implementations
To run these tests against a new Protocol Buffers implementation, write a program in your language that uses the protobuf implementation you want to test. This program should implement the testing protocol defined in conformance.proto. This is designed to be as easy as possible: the C++ version is only 150 lines and is a good example for what this program should look like (see conformance_cpp.cc). The program only needs to be able to read from stdin and write to stdout.
Portability
Note that the test runner currently does not work on Windows. Patches to fix this are welcome! (But please get in touch first to settle on a general implementation strategy).
