ci(cpp): install a relocatable CTestTestfile.cmake for packaged C++ tests - #2097
ramakrishnap-nv wants to merge 3 commits into
Conversation
Switches ConfigureTest and the remaining hand-rolled add_test() call sites to rapids_test_add(), and adds rapids_test_install_relocatable() so the libcuopt-tests conda package ships a working CTestTestfile.cmake, matching cudf's approach. run_ctests.sh is untouched -- it still execs the raw binaries it always has. This only adds the ability to run `ctest` directly against the installed package; a later PR will use that (via `ctest -L`) to let CI skip routing's test binaries when a PR doesn't touch routing.

capture its output and fail when no tests are registered. Assert a nonzero test
count or the expected test name so this check verifies registration in the
installed registry.

Assert that the installed registry contains tests.
ctest -N can succeed when it lists zero tests. In that case, this temporary check would pass without verifying the registration that this PR adds. Capture its output and assert an expected test name or a nonzero test count. (docs.rapids.ai)

CI Test Summary✅ All 32 test job(s) passed. |
Confirmed in CI across all 8 conda-cpp-tests matrix entries (V100, A100, 2x H100, 2x L4, RTX Pro 6000): 'ctest -N' lists all 23 registered tests against the installed libcuopt-tests package, and the existing gtest suite (unmodified run_ctests.sh) still passes cleanly. ci/test_cpp.sh is now byte-identical to main.

First of a few small PRs toward letting CI skip routing's C++ test binaries when a PR doesn't touch routing (follow-up to the libcuopt wheel split).\n\nPlumbing only -- no change to what actually runs today. Switches
ConfigureTestand every hand-rolledadd_test()call site (including the gRPC tests) torapids_test_add(), and addsrapids_test_install_relocatable()solibcuopt-testsships a workingCTestTestfile.cmake, matching cudf's approach.ci/run_ctests.shis untouched -- it still execs the raw binaries it always has.\n\nValidated in CI (then reverted the throwaway check):ctest --test-dir ‹installed libcuopt-tests package› -Ncorrectly lists all 23 registered tests (including every routing test) against the real installed conda package, confirmed across all 8conda-cpp-testsmatrix entries (V100, A100, 2x H100, 2x L4, RTX Pro 6000). The existing gtest suite itself still passes unchanged.\n\nNext PRs: addLABELS routingto the routing-only test binaries, then wirerun_ctests.shto skip them via a new changed-files group.
