What it does
Testing Quality Standards is an agent skill from athola/claude-night-market. Defines testing quality metrics, coverage thresholds, and anti-patterns. Use when establishing test gates or validating a test suite's coverage targets.
Its SKILL.md is about 990 tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files (for example `modules/anti-patterns.md`, `modules/best-practices.md` and `modules/content-assertion-levels.md`).
It sits in Testing & QA, covering Test generation. The repository describes itself as: 23 Claude Code plugins: TDD enforcement hooks, git/PR workflows, spec-driven development, code review, project lifecycle, fix-from-error, maintenance automation, context… The licence is MIT.
When your agent uses it
- Establishing test gates
- Validating a test suites coverage targets
Example prompts
- “Use the testing-quality-standards skill to define testing quality metrics, coverage thresholds, and anti-patterns”
- “/testing-quality-standards”
Requirements
- Python 3
What it can do on your machine
Read from SKILL.md and the folder at commit 9f3eb00. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
pytestpip
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use pip, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Testing Quality Standards loads about 994 tokens when it runs. Until then it costs about 45 tokens; SKILL.md has 366 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Testing Quality Standards
Shared quality standards and metrics for testing across all plugins in the Claude Night Market ecosystem.
When To Use
- Establishing test quality gates and coverage targets
- Validating test suite against quality standards
When NOT To Use
- Exploratory testing or spike work
- Projects with established quality gates that meet requirements
Coverage Thresholds
| Level | Coverage | Use Case |
|---|---|---|
| Minimum | 60% | Legacy code |
| Standard | 80% | Normal development |
| High | 90% | Critical systems |
| detailed | 95%+ | Safety-critical |
Quality Metrics
Structure
- Clear test organization
- Meaningful test names
- Proper setup/teardown
- Isolated test cases
Coverage
- Critical paths covered
- Edge cases tested
- Error conditions handled
- Integration points verified
Maintainability
- DRY test code
- Reusable fixtures
- Clear assertions
- Minimal mocking
Reliability
- No flaky tests
- Deterministic execution
- No order dependencies
- Fast feedback loop
Detailed Topics
For implementation patterns and examples:
- Anti-Patterns - Common testing mistakes with before/after examples
- Best Practices - Core testing principles and exit criteria
- Content Assertion Levels - L1/L2/L3 taxonomy for testing LLM-interpreted markdown files
Integration with Plugin Testing
This skill provides foundational standards referenced by:
pensive:test-review- Uses coverage thresholds and quality metricsparseltongue:python-testing- Uses anti-patterns and best practicessanctum:test-*- Uses quality checklist and content assertion levels for test validationimbue:proof-of-work- Uses content assertion levels to enforce Iron Law on execution markdown

Troubleshooting

Common Issues
Tests not discovered
Ensure test files match pattern test_*.py or *_test.py. Run pytest --collect-only to verify.
Import errors
Check that the module being tested is in PYTHONPATH or install with pip install -e .
Async tests failing
Install pytest-asyncio and decorate test functions with @pytest.mark.asyncio
Exit Criteria
- Coverage threshold met for the project tier: 60% minimum for
legacy code, 80% for normal development, 90% for critical
systems, 95%+ for safety-critical; measured with
pytest --covand threshold enforced inpyproject.toml - All four quality metric checklists pass: Structure (clear organization, meaningful names, setup/teardown, isolation), Coverage (critical paths, edge cases, error conditions, integration points), Maintainability (DRY fixtures, clear assertions, minimal mocking), Reliability (no flaky tests, deterministic execution, no order dependencies)
- Test files match discovery pattern
