llvm dev - Feb 2016 - New contributor, `make test` not doing anything

I came to the recent LLVM/Clang hackathon and made a new checker for
clang-tidy. I'm working on wrapping up and submitting my patch, and I
can't
seem to run the tests.

- First, I followed the instructions at
http://clang.llvm.org/hacking.html#testingNonWindows. I ran `make test` in
my build directory, and also tried running `make` in the `test`
subdirectory. They both exited in under a second with no output.

- Then, I tried doing the same thing in the `tools/clang/tools/extra`
subdirectory of my build directory, where clang-tidy lives. Same result.

- Finally, I found http://clang.llvm.org/extra/clang-tidy/#testing-checks.
This explains how to create tests but not how to run them. I made a
relatively wonky command line that seems to run my test successfully (along
the lines of `PATH=$PATH:$BUILD_DIR/bin ./check_clang_tidy.py
../../test/clang-tidy/misc-my-check.cpp misc-my-check /tmp/foo.tmp`), but
it doesn't feel right.

What should I be doing instead?

You'll probably have better chance on the cfe-dev mailing-list
(LLVM-dev to BCC).

Hi,

I haven't come across 'make test' before and this target doesn't
exist when building with ninja. I'm guessing that make is checking whether
'test' is up to date, finding the './test' directory, and
concluding there's nothing to do.

I think you're looking for 'make check-all'. There's various
check-* targets for particular subsets of the tests but I don't know the one
for clang-tidy's tests.
