| // To test the code generator, we actually use it to generate code for |
| // google/protobuf/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. |
