hilla-ui-test is a skill for Claude Code from AI-Unified-Process/marketplace. It costs 224 tokens per session (608 once invoked), scanned A, original, Apache-2.0.

A skill for writing browser-based tests for Hilla React views using Vitest and React Testing Library. Hilla is a Java and web UI framework, and these tests check what a person sees without starting a server or database.

In plain words
What is it for?
Use it to test rendering, form input, validation, mocked endpoint calls, alternative outcomes, and endpoint access and error behavior.
Why use it?
It verifies form behavior, validation, endpoint calls, and displayed outcomes while keeping the UI tests independent from backend services.

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

hilla-ui-test 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 today.

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.

What it actually says

Hilla UI Test

Instructions

Write the UI layer tests of the use case $ARGUMENTS for the Hilla view with Vitest in browser mode and React Testing Library, the generated endpoint clients mocked with vi.spyOn — no server, no database. Each suite is src/main/frontend/tests/UC-XXX-<slug>.test.tsx with describe('UC-XXX: <name>').

Run Directly or from /use-case-test

Run from /use-case-test, this skill follows that skill's sections "If Tests for This Use Case Already Exist", "When a Test Fails", and "Which Layer Tests What"; it does not repeat them. The specification is the oracle: take every expected value from it, never from what the code returns.

What to Test

What the actor sees: rendering, form validation, the call the view makes, and the message the specification states for each outcome and alternative flow. The business rules are tested by the integration layer's test skill. Also write one Java test of the endpoint, UC<id><Name>EndpointTest: its access annotation and the EndpointException message of each alternative flow.

Markers

Keep this skill's rows in the Markers table of docs/architecture/stack.md exactly as references/markers.md lists them: add them when they are missing, correct them when they differ. Touch no other row.

Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
