42// This defines the conformance testing protocol.  This protocol exists between
43// the conformance test suite itself and the code being tested.  For each test,
44// the suite will send a ConformanceRequest message and expect a
45// ConformanceResponse message.
46//
47// You can either run the tests in two different ways:
48//
49//   1. in-process (using the interface in conformance_test.h).
50//
51//   2. as a sub-process communicating over a pipe.  Information about how to
52//      do this is in conformance_test_runner.cc.
53//
54// Pros/cons of the two approaches:
55//
56//   - running as a sub-process is much simpler for languages other than C/C++.
57//
58//   - running as a sub-process may be more tricky in unusual environments like
59//     iOS apps, where fork/stdin/stdout are not available.
