vaadin-e2e-test

vaadin-e2e-test is a skill for Claude Code from AI-Unified-Process/marketplace. It costs 222 tokens per session (524 once invoked), scanned A, original, Apache-2.0.

A guide for writing browser-based end-to-end tests for Vaadin Flow or Hilla applications using Playwright for Java. It uses Drama Finder wrappers, which provide typed controls designed to support accessibility.

In plain words
What is it for?
It helps create tests for use cases and test-case journeys, including alternative flows and assertions for each expected result.
Why use it?
It gives a consistent way to check complete user journeys against a running application, using expected values from the specification rather than accidentally copying the application's current output.

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

vaadin-e2e-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

Vaadin E2E Test

Instructions

Write browser tests against the running application with Playwright for Java and the Drama Finder element wrappers: UC<id><Name>IT for a use case — its main success scenario and the alternative flows an actor sees — or TC<id><Name>IT for a test case journey, with one // Step <n>: <name> comment per Flow row and one assertion per Validation item.

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.

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

2 files 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.
