run-tests

A testing workflow for the OhMyCode project that runs its pytest test suite and examines the results. Pytest is a tool for automatically running Python tests.

In plain words
What is it for?
Use it to run all tests or a selected area, such as tools, core loop code, providers, configuration, or skills, then analyze failures.
Why use it?
It checks code changes for broken behavior and helps identify what failed before a fix is committed.

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

run-tests 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 2d ago.

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.

Run Tests for OhMyCode

Run the project test suite, analyze results, and take action on failures.

This skill is part of the OhMyCode development closed-loop:

编码 ──→ /gen-tests ──→ /run-tests ──→ 分析失败 ──→ 修代码 ──╮
 ↑                                                            │
 ╰────────────────────────────────────────────────────────────╯

When to Use

  • After /gen-tests generates new test files — verify them immediately
  • After editing any source code in ohmycode/ — catch regressions
  • After fixing a bug found by a previous /run-tests — confirm the fix
  • Before committing — full suite gate
  • User says "run tests", "check tests", "verify tests"

Input

$ARGUMENTS — optional scope specifier. If empty, run the full suite.

Argument pytest path
(empty) tests/ (full suite)
tools tests/tools/
tools/bash tests/tools/test_bash.py
core tests/core/
core/loop tests/core/test_loop.py
providers tests/providers/
config tests/config/
skills tests/skills/
specific file path use as-is

Step 1 — Determine Scope

Resolve $ARGUMENTS to a pytest target path using the table above.

If a specific file is given, verify it exists. If not, check for the closest match under tests/.

Step 2 — Run Tests

python3 -m pytest <resolved_path> -v --tb=short 2>&1 | tee tests_run.log

Use -v for verbose output and --tb=short for concise tracebacks.

Step 3 — Analyze Results

All passed

Report the result summary (e.g., "73 passed in 2.1s") and confirm the code is healthy. No further action needed.

Failures detected — enter fix loop

For each failure:

  1. Read the traceback from the test output
  2. Classify the root cause:
    • Test bug — the test itself has a wrong assertion or outdated expectation
    • Implementation bug — the source code under test has a defect
    • Environment issue — missing dependency, import error, fixture mismatch
  3. Fix it:
    • For test bugs: fix the test code directly
    • For implementation bugs: fix the source code in ohmycode/
    • For environment issues: install missing deps or fix config
  4. Re-run /run-tests — repeat until all green ✓

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.

run-tests is a skill published in the GitHub repository AlphaLab-USTC/OhMyCode (131 stars, last pushed 5mo ago), licensed MIT. It adds 32 tokens to every session and 996 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
