Skill

End-to-End Testing

Verify the running app against requirements; retrigger the build loop on failure.

// workflow;

Behaviour

What it does

Maps acceptance criteria to real scenarios through HTTP, CLI, or browser
Uses node:test for APIs and CLIs; Playwright via node:test for web UIs
Runs against a real running app, not mocks
Files fix tasks and sends control back to the build loop on failure
Hands off to shipping only when end-to-end verification passes

When to use

Good fits

After executing-plans, when the unit suite is green

When you need proof the whole app works, not just the pieces

Before shipping any feature with user-facing behaviour

Development harness

Outer gate

Part of the design-to-ship pipeline: brainstorming → technical-documentation → conformance-check → reconciling-changes → planning → project-setup → executing-plans → shipping. Install the full set for structured feature work.

Used inside executing-plans as the outer verification gate before shipping.
