> I would expect a mature code base like rsync to have a lot of unit tests and integration tests You might be surprised. C applications which interact heavily with the system - like rsync - can be tricky to test comprehensively, as it's nontrivial to inject faults into system calls. If the application is architected to support this kind of testing, or uses a HAL, that may make matters easier - but an older codebase like rsync probably isn't. |
