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