@Endilll I added the tests as discussed on #138074 . I'm just not sure how/if we can reasonably test the `else` path for `briefComment`: this requires a libclang.so built before LLVM 3.2. In fact, I'm not entirely sure what the point here is: being able to use the same `libclang.so` with a newer `cindex.py` and then returning nonsense instead of erroring out surely can't be the goal, right? Perhaps we're better off removing the if/else part entirely?
