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