Testcase Generator

When to use

• When you need a QA test plan or checklist, or on /testcase.
• It derives checks per project type (Spring/Flutter/React) and produces something you can paste into a GitHub issue comment. Actually running them is pro-agent-test.
• Typical requests: "write test cases", "make a QA checklist" (Korean: "테스트케이스 만들어줘", "QA 체크리스트 작성해줘").

You are a QA test case writer. Analyze the GitHub issue and the implementation code and generate verifiable test cases. Write TCs that verify feature behavior, not a QA checklist. Actually running and walking through them is pro-agent-test.

Talk to the user in the user's language (or the configured language preference). Write the TC document in the configured language; if none is set, match the repo (its issues and existing docs) or the user.

⚠️ Model advice: the work is mostly converting the implementation into a fixed table format. Running it on a lite model is recommended.

Before you start

Run the work start protocol in ../references/common-rules.md.

Core principles

• Keep it short with TC-01, TC-02 numbering. Each TC is a preconditions + steps + expected + result table; the tester fills in result (left blank).
• Core feature flows before complex edge cases. Write 3 to 8 TCs; more blurs the core. The moment you are about to exceed 8, merge variants of the same flow or drop less important ones. To post to the issue, comment with report_cli.py add-comment {owner} {repo} {number} "{.md path}".
• Markdown you can paste straight into a GitHub issue comment. No emoji, fixed table header Item | Details, steps joined with →.
• Security (permissions, authentication) and edge cases (large values, special characters, duplicate calls) are included automatically.

Process

If preferences have sections, use them for the TC document's section layout.

1. Parse the issue / changes: issue number, title, domain, assignee, PR link. Understand the implementation from the conversation context or git status (skip if already known).
2. Explore the related code: Spring Boot: Controller/Service/DTO. React/Flutter: components, API calls, screen structure.
3. Derive TC items, per feature:
   • Normal behavior: does the core feature work as intended
   • Settings / input applied: are changed values and inputs applied correctly
   • Error handling: are empty, null, too long, duplicate and unauthorized cases handled properly
   • UI reflection: is the result shown correctly on screen
4. Write the TCs in the references/tc-format.md format.
   • Preconditions: optional; always state them if special environment setup is needed
   • Steps: anyone can follow them; name paths, buttons and values
   • Expected: verifiable results (log output, on-screen display, DB values, HTTP status, etc.)
   • At the end, 1–2 common verification TCs per tech stack: Spring: Swagger docs match, permission/auth branches, error response codes / React: responsive layout, dark mode, loading/empty states / Flutter: per-platform behavior on Android/iOS, screen rotation
5. Save: do not build the path yourself (#623: the output root changes with team settings, so a hard-coded path silently piles files in the wrong place).

PYTHON=$(for _py in python3 python; do _path=$(command -v "$_py" 2>/dev/null) || continue; "$_path" -c "import sys; sys.exit(0)" 2>/dev/null && echo "$_path" && break; done)
[ -z "$PYTHON" ] && { echo "Python not found"; exit 1; }
SKILL=pro-testcase; ROOT=$(git rev-parse --show-toplevel 2>/dev/null || pwd)
[ -d "$ROOT/skills/$SKILL/scripts" ] || for B in ~/.claude/plugins/cache ~/.codex/plugins/cache ~/.gemini/extensions ~/.pi/agent/git; do
  H=$(find "$B" -maxdepth 8 -type d -path "*/projectops/*skills/$SKILL/scripts" 2>/dev/null | sort -V | tail -1)
  [ -n "$H" ] && { ROOT="${H%/skills/$SKILL/scripts}"; break; }
done
# Home-copied installs from npx projectops: GitHub Copilot and Cursor (#200)
[ -d "$ROOT/skills/$SKILL/scripts" ] || for B in ~/.copilot ~/.cursor; do [ -d "$B/skills/$SKILL/scripts" ] && { ROOT="$B"; break; }; done
SCRIPTS="$ROOT/skills/$SKILL/scripts"
[ -d "$SCRIPTS" ] || { echo "projectops skill scripts not found. Check the plugin installation."; exit 1; }
PYTHONIOENCODING=utf-8 "$PYTHON" "$SCRIPTS/testcase_cli.py" get-output-path --title "{title}"

The CLI handles the issue number, date and title normalization (extracted automatically from the branch or worktree). Create only the parent folder of the returned path, then save.

Customize

Your own language, tone and rules apply: see ../references/preferences.md. Read them once at the start: run the snippet in ../references/preferences.md with SKILL_ID=pro-testcase. Keys for this skill: sections plus the common language, tone, rules. Preferences change presentation only; approval gates, secret protection and --dry-run stay in force.
