hypothesis-test target breaks when no hypothesis tests exist (exit code 5 not handled)

[tschm]

Summary

The hypothesis-test target in .rhiza/make.d/test.mk fails with make exit code 2 when no hypothesis/property tests are found, because pytest exits with code 5 ("no tests collected") which is not handled.

History

This was previously fixed in downstream repos (e.g. commit 000589f in tschm/jquantstats: "Handle pytest exit code 5 in hypothesis-test target"), but the fix was removed by the rhiza sync in commit ff19245 ("sync").

Affected template file

.rhiza/make.d/test.mk — the hypothesis-test:: target

Current behaviour

============================ 96 deselected in 1.64s ============================
make: *** [.rhiza/make.d/test.mk:104: hypothesis-test] Error 5
Error: Process completed with exit code 2.

Pytest exit code 5 means no tests were collected, which is expected for projects that use the hypothesis or property marker but have no such tests yet.

Expected behaviour

When pytest exits with code 5, the target should print a warning and exit cleanly (code 0), matching the same pattern already used for the early-exit check at the top of the target.

Fix

Capture the exit code and treat 5 as a warning:

PYTEST_HTML_TITLE="Hypothesis tests" ${UV_BIN} run pytest \
  --ignore=${TESTS_FOLDER}/benchmarks \
  -v \
  --hypothesis-show-statistics \
  --hypothesis-seed=0 \
  -m "hypothesis or property" \
  --tb=short \
  --html=_tests/hypothesis/report.html; \
code=$$?; \
if [ $$code -eq 5 ]; then \
  printf "${YELLOW}[WARN] No hypothesis/property tests found, skipping.${RESET}\n"; \
  exit 0; \
fi; \
exit $$code

This is the same pattern that was previously in the template and was inadvertently dropped.
