testing.update_test_outcomes

testing.update_test_outcomes is a skill for Claude Code from gpsaggese/helpers. It costs 8 tokens per session (688 once invoked), scanned A, original, Apache-2.0.

A unit-test expectation updater for tests whose actual output no longer matches the expected output. It reruns each test, identifies the assertion used, and reports the result before updating outcomes.

In plain words
What is it for?
Use it to review and update expected strings, values, or other results in a supplied list of failing tests or a reproduction script.
Why use it?
It helps distinguish a changed, valid result from a real code defect before test expectations are changed. Running tests individually also makes each mismatch easier to inspect.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

testing.update_test_outcomes scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 71 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Goal

  • The user passes a list of tests, or a repro script, with failing tests <FAILING_TESTS> whose actual and expected outputs mismatch

Important

  • For all code, follow .claude/skills/coding.rules.md
  • Follow the invariants and conventions for unit tests in .claude/skills/testing.rules.md

Workflow

Run the Failing Tests

  • Run the tests one at a time, the way the user suggested, to confirm they fail due to mismatching outputs

Classify the Assertion Method

  • For each failing test method, check whether the result is checked with

    • self.check_string()
    • self.assert_equal() or a similar assertion (e.g., hunteuti.assert_sys_calls(), self.assertEqual())
  • Print a table with the following info: path of test | fail / pass | check_string or assert_equal

    | Path | Test | Status | Assertion Method |
    |------|------|--------|------------------|
    | dev_scripts_helpers/documentation/test/test_notes_to_pdf.py | Test_notes_to_pdf_latex_options::test1 | FAIL | self.assert_equal() with fuzzy_match=True |
    | dev_scripts_helpers/documentation/test/test_notes_to_pdf.py | Test_notes_to_pdf_latex_options::test2 | FAIL | self.assert_equal() with fuzzy_match=True |
    | dev_scripts_helpers/documentation/test/test_notes_to_pdf.py | Test_notes_to_pdf_output_types::test1 | FAIL | self.assert_equal() with fuzzy_match=True |
    
  • Save this to tmp.update_test_outcomes.failing_tests.md

Update the Expected Output

  • For each failing test method:
    • If the result is checked with self.check_string()
      • Run the test with the pytest option --update_golden to refresh the output
    • If the result is checked with self.assert_equal() or a similar assertion (e.g., hunteuti.assert_sys_calls()), read the file <TEST_DIR>/tmp.initial.actual.txt (e.g., dev_scripts_helpers/documentation/test/outcomes/Test_run_pandoc_to_html.test1) that holds the actual variable, and update the expected variable
      • E.g.,
        expected = """
        [{'args': (f'jupytext --to ipynb --update {py_file}',),
          'function': 'hsystem.system',
          'kwargs': {}},
         {'args': (f'jupytext --sync {py_file}',),
          'function': 'hsystem.system',
          'kwargs': {}}]
        """

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
