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
since all the tests depend on it.
To run the tests against the C++ implementation, run:
$ cd conformance && make test_cpp
$ cd conformance && make test_nodejs
To run the Ruby tests against MRI, first build the C extension:
$ cd ruby && rake
Then run the tests like so:
$ cd conformance && make test_ruby
Most of the languages in the Protobuf source tree are set up to run
conformance tests. However some of them are more tricky to set up
tests.sh in the base of the repository to see
how Kokoro runs the tests.
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.
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).
