// To test the code generator, we actually use it to generate code for
// net/proto2/internal/unittest.proto, then test that. This means that we
// are actually testing the parser and other parts of the system at the same
// time, and that problems in the generator may show up as compile-time errors
// rather than unittest failures, which may be surprising. However, testing
// the output of the C++ generator directly would be very hard. We can't very
// well just check it against golden files since those files would have to be
// updated for any small change; such a test would be very brittle and probably
// not very helpful. What we really want to test is that the code compiles
// correctly and produces the interfaces we expect, which is why this test
// is written this way.
