test-case-analysis

test-case-analysis is a skill for Claude Code from arozumenko/sdlc-skills. It costs 64 tokens per session (4,986 once invoked), scanned A, original, MIT.

A manual process for exploring a test case in a live application before automated testing is written. It produces an Automation-Friendly Spec, a document containing observed behavior and usable selectors.

In plain words
What is it for?
Use it to run a test case step by step, find stable selectors, record defects, decide whether the case can be automated, and prepare instructions for the engineer who writes the test.
Why use it?
It prevents automation from being based only on what a test case claims, which may differ from how the application actually behaves.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

test-case-analysis scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 405 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Test Case Analysis

Execute a TMS test case against the live app, observe what actually happens, and emit an Automation-Friendly Spec (AFS) a downstream engineer can implement without re-exploring.

Core philosophy: a written test case is a hypothesis. The app is the only source of truth. This skill never trusts the case as authored — it runs it step by step, captures stable selectors, flags defects, and only then produces a spec.

Absolute boundaries

  • No automation code. No .spec.ts, no test_*.py, no step definitions. The output is a markdown AFS file. Automation is implemented downstream — your agent knows which role / workflow picks the AFS up.
  • No automating un-automatable cases. Physical device, visual judgment that can't be asserted, flows that genuinely can't be scripted — mark the AFS un-automatable and stop.
  • No skipping exploration. Even if the TMS case looks complete, execute it. The case describes intent; only execution reveals truth.

Analyst slot contract

This skill IS the analyst slot in the test-automation pipeline. When dispatched — by an orchestrator like test-automation-lead, or standalone for "analyse SCRUM-T101" — role, context, parameters, and return shape are fixed here so dispatch prompts don't have to inline them.

Role. Execute one TMS test case end-to-end against the live app, capture stable selectors, classify the finding, emit an AFS. No automation code (see § Absolute boundaries).

Session context — read once at session start. Typically auto-imported via @-blocks in your agent's AGENT.md; if your agent doesn't auto-import, read them now:

  • .agents/profile.md — project systems, base URL, credentials matrix, sample users, bug filing target
  • .agents/workflow.md — branch/PR rules, EPIC pattern
  • .agents/testing.md — framework, locator strategy, TMS case-gate exclusion list
  • .agents/memory/<your-agent>/project_briefing.md — accumulated project gotchas from prior sessions
  • .agents/architecture.md — the surfaces you'll touch (also referenced in Phase 2)

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
