| // This test is meant to verify the interaction of the most common and |
| // representative edition features. Each new edition feature must have its own |
| // unit test and we'll selectively accept new features when we believe doing so |
| // improves test coverage in a meaningful way. |
| // |
| // Note that new features that break the backward compatibility poses challenges |
| // to shared unit tests infrastructure this test uses. It may force us to split |
| // the shared tests. Keep the shared unit tests (message_unittest.inc) |
| // representative without sacrificing test coverage. |
