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 testin my build directory, and also tried running
testsubdirectory. They both exited in under a second with no output.
Then, I tried doing the same thing in the
tools/clang/tools/extrasubdirectory 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?
