1. Jonathan N: Test harness is an important part of the development
process, shapes what kinds of tests people write. What can we improve?
2. Peff: I love our test harness
3. Brian: It’s amazing for integration tests. For our C code it’s a
lot harder to do unit tests. We sometimes have a portability issue,
about POSIX shell vs others.
4. ZJ: I like how it also acts as a piece of documentation.
5. Jonathan N: If we had more unit tests: if I am working on refs, I
might like to run all tests related to that. And now we have this lack
of dependency graph between this
6. Peff: I’m super nervous about that. Tools like code coverage could
do this. But I’ve seen cases where all new tests are green, and tests
in the area I expected they succeed. But at some far corner it seems to
fail. So you’re optimizing for speed, might be losing in correctness.
I’m biased because I can run all tests on my computer in 1 minute. But
for Windows this doesn’t seem to work that.
7. Peff: We can spend time on speeding up things, making it better
parallelized for example. I’ll send some patches out on this.
8. Jonathan N: Really nice contribution to Git by David Barr, whose
background was as a Java developer and thus the code was written in a
Java way with clear API boundaries and unit tests.
9. Brian: Yes if your function is doing too much, it should be split up
making it possible to test the separate pieces and then have a function
that calls those and tests the end result.
