PDF Hell ships JUnit XML output and a --fail-threshold CI gate — drop it into any CI runner that renders JUnit (which is all of them).

GitHub Actions

Failures show up as red rows on the PR with the expected and observed answers in the failure message. The audit ZIP is downloadable from the workflow artifacts — attach it to a procurement appendix without any post-processing.

pytest integration

pdfhell isn’t a pytest plugin (deliberately — it’s a benchmark, not a test framework), but you can call the runner from a pytest test: 
# tests/test_pdfhell_gate.py
import subprocess

def test_pdfhell_passes():
    result = subprocess.run(
        ["pdfhell", "run",
         "--model", "anthropic:claude-sonnet-4-6",
         "--suite", "smoke",
         "--fail-threshold", "0.7",
         "--quiet"],
        capture_output=True,
    )
    assert result.returncode == 0, result.stdout.decode()
Run with pytest tests/test_pdfhell_gate.py. If your CI uses pytest already, this slots into the existing test pipeline without changing the report format.

Reading the JUnit output

JUnit dialect — passes, failures, and “skipped” (refusals): 
<testsuites>
  <testsuite name="pdfhell.mini.anthropic.claude-sonnet-4-6" tests="30" failures="1" errors="0" skipped="0">
    <testcase name="hidden_ocr_mismatch-1001" classname="hidden_ocr_mismatch"/>
    <testcase name="footnote_override-2010" classname="footnote_override">
      <failure type="fell_for_trap" message="expected='12 month'; got='The cap is 24 months...'">
        expected_answer: 12 month
        model_output:    The cap is 24 months of fees paid.
        matched_forbidden: ['The cap is 24 months of fees paid.']
        failure_mode: Model reads the body clause and ignores the 6pt footnote.
      </failure>
    </testcase>
  </testsuite>
</testsuites>
Failure types:
  • fell_for_trap — the model returned exactly the wrong answer the trap was designed to elicit. A known failure mode. Most diagnostic.
  • hallucination — the model returned something neither expected nor forbidden. A different kind of wrong.
Skipped cases are model refusals ("I can't determine...") — they don’t count as quality failures, but they don’t count as passes either.

​
The audit pack

--audit-pack <path> writes a ZIP procurement teams can attach to a diligence appendix. Contents: 
audit-pack.zip
├── manifest.json       # SHA-256 of every file in the pack
├── README.txt          # What's in the ZIP + how to verify the hashes
├── run.json            # Full run report
├── run.xml             # JUnit XML
└── cases/
    ├── hidden_ocr_mismatch-1001.pdf
    ├── hidden_ocr_mismatch-1001.json
    └── ...             # every PDF the model was tested against + its answer key
Auditors verify the pack with: 
unzip -p audit-pack.zip manifest.json | jq .files
sha256sum cases/*.pdf cases/*.json run.json run.xml README.txt
# Compare each hash against the manifest entry.
If any file in the ZIP was edited after delivery, its hash diverges from the manifest and verification fails. Tamper-evident by construction.
