E2E Testing

Conventions

• e2e/*.spec.ts -- all e2e tests use .spec.ts
• Name by feature: login.spec.ts, create-topic.spec.ts
• Selectors: getByRole > getByLabel > getByText > getByTestId > CSS
• Test IDs: {feature}-{element}, {feature}-{element}-{index}, {feature}-{state}

Edit-time Hooks

• route sibling test: when a route or *.page.tsx changes, run sibling *.browser.test.* or *.integration.test.*; block if it fails.
• structural refactor test nudge: new *.page.tsx or split component file needs accompanying .test, .integration.test, or .browser.test.

Accessibility -- axe on every page
