Awesome Test Case Design — v2

Partner with Treeify — We co-build real testing content (mini-projects, playbooks, teaching kits) and co‑market responsibly.
KOLs, teams, and tool makers welcome. Join the Partnership Program →

Build predictable, evidence-driven test design — from ideas to runnable cases with oracles and observability (logs/metrics/traces).
v2 adds deeper field experience, broader audience coverage, and ready‑to‑use templates, mini‑projects, and AI guardrails.

Quick start

1. Read Quickstart (time‑boxed tracks, role shortcuts).
2. Pick a mini‑project (e.g., Discount Code or Refund Workflow).
3. Use MAE → write scenarios → add cases → attach evidence (msgids, metrics, traces).

New here? Skim the Glossary, then try one MAIN + one EXC path.

What’s inside (v2 highlights)

• Field Notes — hard‑won patterns, postmortems, before/after coverage.
• Fundamentals — coverage thinking, flows & states, risk‑based priorities.
• Techniques — boundary/equivalence, decision tables, state models, pairwise, CRUD grids.
• Scenario Patterns — MAE, roles/permissions, data lifecycle, cross‑feature.
• API & Contracts — idempotency, retries, pagination, error taxonomy, schemas.
• Non‑functional — performance p95/p99, resiliency/timeouts, security, compatibility, a11y, privacy.
• Domain Playbooks — payments/checkout, messaging, mobile, B2B, i18n, data/ML.
• Cross‑discipline Bridges — for PMs, Devs, SREs, Security/Compliance, Design/UX.
• Checklists & Gates — coverage/API/perf/sec/compat/a11y, review gates, metrics, traceability.
• Mini‑projects — realistic flows with briefs → scenarios → cases (+ evidence bundle).
• AI Augmentation — prompt guardrails, LLM patterns, human‑in‑the‑loop.
• Tools & Integrations — observability hooks, mind‑maps, test manager mappings, export templates.
• Teaching Kits — 60‑min workshop (deck outline + worksheets).
• Community — contribution ideas, style guide.

How to use this repo

• Design: Start with MAE (pattern).
• Decompose: Apply boundary/equivalence and pairwise.
• Decide: Prioritize with risk‑based thinking.
• Observe: Wire observability hooks (msgid, err.code, metrics, traces).
• Prove: Attach an evidence bundle in PRs (HAR/JSON/log/metric/trace).
• Map: If you use TestRail/Xray/Zephyr/ADO, see mapping guide and export templates.

Mini‑projects (start here)

• Discount Code v1 — Brief · Scenarios · Cases
• Refund Workflow v1 — Brief · Design Notes · Scenarios · Cases

AI augmentation (safe & useful)

• Prompt guardrails — explicit‑only, schema discipline, dedup.
• LLM patterns — structured output, RAG with citations, self‑consistency.
• Human‑in‑the‑loop — review rubrics and bounded regenerate cycles.
