What it does
Test Case Design is an agent skill from mirumee/nimara-ecommerce. Turn a requirement, spec, or feature into a gap-free set of test cases by equivalence partitioning — enumerate the distinct behaviour classes, pick a representative per class, then run them and report. Use this skill whenever the user asks to design test cases, write a test plan, cover a feature "with no gaps", build equivalence classes/groups, or test a data-driven surface (like the checkout address fields) across many inputs. Produces a plan file plus a run report; can file findings as bugs. Do NOT use to…
Its SKILL.md is about 700 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Testing & QA, covering Test generation. It works with shadcn/ui. The repository describes itself as: Headless, composable ecommerce storefront built with Next.js, Typescript, and shadcn/ui. The licence is BSD-3-Clause.
When your agent uses it
- The user asks to design test cases
- Write a test plan
- Cover a feature with no gaps
- Build equivalence classes/groups
Example prompts
- “with no gaps”
- “/test-case-design”
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- Partition, don't enumerate inputs. Find the variables that change behaviour; group inputs into equivalence classes where every member…
- Anchor to a source of truth. For data-driven UIs, derive classes from the data (e.g. google-i18n-address all.json…
- No silent gaps. Explicitly list every class and confirm each is covered; call out any class you deliberately skip and why.
- Reuse known behaviour. Field-level validation behaviours are already documented in MEMORY.md and [[Test Data & Fixtures]] — don't re-derive.
What it can do on your machine
Read from SKILL.md and the folder at commit b883dec. 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.
Context cost
Test Case Design loads about 695 tokens when it runs. Until then it costs about 145 tokens; SKILL.md has 274 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.

- description
- Turn a requirement, spec, or feature into a gap-free set of test cases by equivalence partitioning — enumerate the distinct behaviour classes, pick a representative per class, then run them and report. Use this skill whenever the user asks to design test cases, write a test plan, cover a feature "with no gaps", build equivalence classes/groups, or test a data-driven surface (like the checkout address fields) across many inputs. Produces a plan file plus a run report; can file findings as bugs. Do NOT use to retest an existing ticket (use bug-retest-triage).
Test Case Design
Convert a requirement into a complete set of test cases — covering every distinct behaviour class, not random examples — then execute and report. This is how the address admin-area sweep found bugs an ad-hoc pass missed (MS-1238/1239/1240).
Operating principles
- Partition, don't enumerate inputs. Find the variables that change behaviour; group inputs into equivalence classes where every member behaves the same; cover each class with one representative + boundaries. See [[Coverage Maps]].
- Anchor to a source of truth. For data-driven UIs, derive classes from the data (e.g. google-i18n-address
all.jsonrequire/sub_isoids/state_name_type), not from guesses. - No silent gaps. Explicitly list every class and confirm each is covered; call out any class you deliberately skip and why.
- Reuse known behaviour. Field-level validation behaviours are already documented in
MEMORY.mdand [[Test Data & Fixtures]] — don't re-derive.
Workflow
- SCOPE — restate the requirement; identify the behaviour-driving variables (channel, auth, country, payment outcome, field state…).
- PARTITION — build the equivalence-class table: class → rule → expected behaviour → representatives (+ boundary/negative cases). Write it to
qa/triage/plans/<NAME>-tests.md. - PICK DATA — choose verified fixtures per representative from [[Test Data & Fixtures]]; request any missing data/accounts (ASK, never fabricate).
- RUN — execute each case with the cheapest reliable method ([[Test Method Playbooks]]); for data-driven UI, inspect the rendered control per representative (select vs text, required, sorted). Capture evidence →
qa/triage/evidence/<NAME>/results.md. - REPORT — table of class → expected → actual → pass/fail, with the gap analysis (every class accounted for).
- FILE (if asked) — generalise failures into classes and file bugs + a
[DEV]spec ticket thatBlocksthem, per [[Defect Taxonomy & Severity]] and [[Jira & Board 74 Operating Manual]].

Test Case Design is an agent skill from mirumee/nimara-ecommerce. Turn a requirement, spec, or feature into a gap-free set of test cases by equivalence partitioning — enumerate the distinct behaviour classes, pick a representative per class, then run them and report.
When should I use Test Case Design?
Test Case Design fits situations like: the user asks to design test cases; write a test plan; cover a feature with no gaps; build equivalence classes/groups.
How do I install Test Case Design in Claude Code?
Run `npx skills add mirumee/nimara-ecommerce --skill test-case-design -a claude-code`. Or copy the skill folder (.claude/skills/test-case-design in mirumee/nimara-ecommerce) into .claude/skills/test-case-design in your project. Claude Code loads it when a task matches its description.
How do I install Test Case Design in Codex?
Run `npx skills add mirumee/nimara-ecommerce --skill test-case-design -a codex`. Or copy the skill folder (.claude/skills/test-case-design in mirumee/nimara-ecommerce) into .agents/skills/test-case-design in your project. Codex loads it when a task matches its description.
Can I use Test Case Design in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add mirumee/nimara-ecommerce --skill test-case-design -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/test-case-design, .gemini/skills/test-case-design, .github/skills/test-case-design and .opencode/skills/test-case-design in your project.
What does Test Case Design need to run?
SKILL.md names no scripts, command-line tools or credentials: Test Case Design is instructions for the agent only.
Does Test Case Design access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Is Test Case Design safe to install?
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
What licence does Test Case Design use?
Test Case Design is published under the BSD-3-Clause licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
How many tokens does Test Case Design use?
About 695 tokens (SKILL.md is roughly 2.8k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
What are the alternatives to Test Case Design?
Skills that share tags, products or a category with Test Case Design: Write and Verify Playwright Tests (appsmithorg/appsmith, 41k stars), Adk Verify Snippets (google/adk-python, 22k stars), Engine E2E (wix/react-native-navigation, 13k stars) and Hermetic Python Unit Tests (dimensionalOS/dimos, 4.6k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
