1Protocol Buffers - Google's data interchange format 2=================================================== 3 4[](https://travis-ci.org/google/protobuf) 5 6Copyright 2008 Google Inc. 7 8This directory contains conformance tests for testing completeness and 9correctness of Protocol Buffers implementations. These tests are designed 10to be easy to run against any Protocol Buffers implementation. 11 12This directory contains the tester process `conformance-test`, which 13contains all of the tests themselves. Then separate programs written 14in whatever language you want to test communicate with the tester 15program over a pipe. 16 17Before running any of these tests, make sure you run `make` in the base 18directory to build `protoc`, since all the tests depend on it. 19 20 $ make 21 22Then to run the tests against the C++ implementation, run: 23 24 $ cd conformance && make test_cpp 25 26More tests and languages will be added soon! 27 28Testing other Protocol Buffer implementations 29--------------------------------------------- 30 31To run these tests against a new Protocol Buffers implementation, write a 32program in your language that uses the protobuf implementation you want 33to test. This program should implement the testing protocol defined in 34[conformance.proto](https://github.com/google/protobuf/blob/master/conformance/conformance.proto). 35This is designed to be as easy as possible: the C++ version is only 36150 lines and is a good example for what this program should look like 37(see [conformance_cpp.cc](https://github.com/google/protobuf/blob/master/conformance/conformance_cpp.cc)). 38The program only needs to be able to read from stdin and write to stdout. 39 40Portability 41----------- 42 43Note that the test runner currently does not work on Windows. Patches 44to fix this are welcome! (But please get in touch first to settle on 45a general implementation strategy). 46
