What it does
Test Architecture Strategy is an agent skill from hashgraph-online/awesome-codex-plugins. Design a sustainable test architecture using test desiderata, test pyramid tradeoffs, fast and slow test separation, integration boundaries, CI feedback loops, and architecture choices that make code testable. Use when a test suite is too slow, too brittle, too mock-heavy, unclear about unit vs integration coverage, or needs a testing strategy before major growth.
Its SKILL.md is about 820 tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files, including reference files (for example `agents/openai.yaml`, `evals/evals.json` and `references/test-architecture-patterns.md`). Compatibility notes: Codex, Claude Code, and other Agent Skills-compatible clients.
It sits in Testing & QA, covering Test strategy and Test generation. The repository describes itself as: A curated list of awesome OpenAI Codex / ChatGPT plugins, skills, and resources. The 1 Codex Marketplace. See live plugins at: https://hol.org/plugins/best-codex-plugins. The licence is MIT.
When your agent uses it
- A test suite is too slow
- Unclear about unit vs integration coverage
- Needs a testing strategy before major growth
Example prompts
- “/test-architecture-strategy”
Requirements
- Compatibility (from SKILL.md): Codex, Claude Code, and other Agent Skills-compatible clients.
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- Inventory the current suite.
- Classify the pain.
- Choose the target shape.
- Move one slice at a time.
What it can do on your machine
Read from SKILL.md and the folder at commit 9e7b281. 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
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
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.
Compatibility
Codex, Claude Code, and other Agent Skills-compatible clients.
From compatibility in the SKILL.md frontmatter.
Context cost
Test Architecture Strategy loads about 824 tokens when it runs, and up to ~1.5k if it reads all its reference files. Until then it costs about 98 tokens; SKILL.md has 354 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.

Test Architecture Strategy
Use this skill to reason about the shape of a test suite, not one test at a time. The goal is a suite that gives confidence, runs quickly enough for flow, and still catches integration failures at important boundaries.
Source Traceability
Primary source: Harry Percival, Test-Driven Development with Python, 3rd ed. Guidance is transformed and paraphrased from chapter 27 and Appendix A, especially test desiderata, fast/slow test tradeoffs, test pyramid thinking, boundaries, ports and adapters, functional core/imperative shell, and when to rethink architecture.
Workflow
Inventory the current suite.
- Identify unit, integration, functional/end-to-end, smoke, and manual checks.
- Capture runtime, flake rate, CI split, and developer feedback path.
Classify the pain.
- Slow feedback.
- Brittle structure-coupled tests.
- Mock-heavy tests with low confidence.
- Missing boundary coverage.
- Too many end-to-end tests.
Choose the target shape.
- Fast tests for core logic and detailed cases.
- Integration tests at real boundaries.
- A small number of end-to-end tests for critical journeys.
- Production monitoring or smoke checks where tests are not enough.
Move one slice at a time.
- Extract pure logic or service boundaries.
- Replace exhaustive end-to-end coverage with lower-level tests plus one journey.
- Add contract or integration checks for external systems.
- Define a runtime red line before the suite becomes painful.
Read test-architecture-patterns.md for audit questions, migration patterns, and decision tables.

Decision Rules
- If tests are slow but valuable, first separate fast local feedback from full CI proof.
- If unit tests require databases or frameworks everywhere, identify pure core logic that can move inward.
- If mocks dominate, use architecture seams rather than more mocks.
- If end-to-end tests cover many detailed branches, demote detailed cases to lower-level tests.
- If integration bugs keep escaping, add boundary tests before deleting broad coverage.
Guardrails
- Do not chase a textbook test pyramid without respecting the product's real risks.
- Do not delete slow tests until replacement confidence exists.
- Do not make every piece of code "pure" at the cost of framework clarity.
- Do not optimize runtime without measuring.
Verification
Before finishing, produce:
- Current suite map.
- Pain classification with evidence.
- Target suite shape.
- First migration slice.
- Verification commands or metrics that prove progress.
