Make CI actually run the test suite (currently 15 of 2,280 tests) #113

Description

@jeremymanning

Part of #108 · Phase 1 · Depends on #109, #110

Problem

CI runs 15 of 2,280 tests (~0.7%).

Workflow What it runs Notes
tests.yml (push/PR) pytest tests/unit/ -m "not real_world" -n 2 mypy step is continue-on-error: true
fast_ci.yml (PR) pytest tests/unit/ -m "not real_world and not slow" failing since 2025-09-03
real_world_tests.yml schedule/dispatch only whole job continue-on-error: true; failed 60/60 recent runs
real-world-tests.yml all three jobs gated if: false "Disabled - requires actual cluster access"

tests/unit/ is 5 files, 391 LOC, 15 tests out of 240 files / 89,950 LOC / 2,280 tests.

~99.3% of the test suite never executes in CI — which is exactly why all 127 failures documented in the sibling issue are invisible, and why fast_ci.yml could fail for a year unnoticed.

There are also two near-duplicate workflow files, real_world_tests.yml and real-world-tests.yml, which is its own source of confusion.

Acceptance criteria

  • CI executes the full non-billable suite on every PR (target >95% of collected tests)
  • All continue-on-error: true removed — including the mypy step in tests.yml
  • No workflow job is gated if: false; either it runs, or the file is deleted
  • The duplicate real_world_tests.yml / real-world-tests.yml pair is consolidated to one
  • Real-world tests run on a schedule against a substrate that actually works (see the HF Jobs issue) rather than against unreachable institutional hosts
  • A red CI is a blocking signal: branch protection requires the test job to pass

Note on sequencing

Turning CI on before fixing the 127 failures will make master permanently red. Land the failure-fix issue first, or gate this behind a temporary allowlist that shrinks to zero — but do not solve it by re-adding continue-on-error.

Verification

gh run list --workflow=tests.yml --limit 1 --json conclusion
# and confirm the run's log reports ~1900 tests collected, not 15

    Resolved

    CI runs the whole non-billable suite. .github/workflows/tests.yml:81:

    pytest tests/ -v --cov=clustrix --cov-report=xml --cov-report=html \
      --cov-report=term-missing --cov-report=json \
      -m "not real_world" --ignore=tests/real_world --ignore=tests/integration

    Not tests/unit/. That command collects 1258 tests on the current tree, against the 15 this issue reported.

    The steps can also fail now:

    $ grep -n "continue-on-error\|--exit-zero\|if: false" .github/workflows/*.yml
    (no matches)
    

    --exit-zero on flake8 and continue-on-error: true on mypy are both gone, so the lint and type steps are load-bearing rather than decorative.

    Recent runs on this branch: Tests success across ubuntu 3.10/3.11/3.12, macos 3.11/3.12 and windows 3.11/3.12; Fast CI success.

    Two related things fixed since:

    • The duplicate real_world_tests.yml workflow — which had failed all 94 of its scheduled runs since 2025-08-24 without ever passing, because it referenced GCP_CREDENTIALS and AZURE_CREDENTIALS, secrets that were never created — was deleted in 0e3490e. Only real-world-tests.yml remains.
    • scripts/check_docs_examples.py now runs in CI too (Fix all broken README/docs examples and unify the version across 4 locations #124).

    One thing I could not verify: whether branch protection on master actually requires the test job. gh api repos/ContextLab/clustrix/branches/master/protection would settle it. A green workflow that is not a required check can still be merged past.
