E2e Example Acceptance

Run example acceptance with executable checks for start/build/preview and browser behavior.

When to Use

• Adding a new examples/<name>/e2e.spec.ts
• Updating an existing E2E case for an example
• Verifying regression fixes in an example before merge
• Confirming no browser console/page/request anomalies during acceptance

Mandatory Acceptance Flow

1. Identify affected examples

   • From changed files, collect all examples/<name>/... paths.
   • If no explicit list is provided, ask for the intended scope.

2. Build each affected example

   • cd examples/<name> && npm run build

3. Run start and preview checks for each affected example

   • For examples with dedicated e2e.spec.ts, run targeted E2E:
   • pnpm run test-e2e -- --example <name>
   • For examples without a dedicated test, run smoke checks manually:
     • cd examples/<name> && npm run start
     • cd examples/<name> && npm run preview

4. Browser-level acceptance criteria

   • Console: no unhandled error/pageerror messages.
   • Network: no unexpected requestfailed entries.
   • Content: assert key selectors/text that prove feature correctness.

5. Update or add E2E tests when needed

   • Prefer dedicated examples/<name>/e2e.spec.ts for feature-specific behavior.
   • Keep assertions deterministic; avoid brittle timing-only checks.
   • Include both start and preview coverage unless the example is explicitly single-mode.

Authoring Template

import { basename, dirname } from "path";
import { fileURLToPath } from "url";
import { expect, startAndTest } from "../../e2e/index.js";

const name = basename(import.meta.url);
const projectPath = dirname(fileURLToPath(import.meta.url));

export default async function (ctx) {
  const runTest = (command?: "start" | "preview") =>
    startAndTest(
      projectPath,
      async (page) => {
        await page.waitForSelector("#root > *", { timeout: 10000 });
        // assert page content and absence of runtime anomalies
      },
      command,
    );

  await ctx.test("e2e start", () => runTest());
  await ctx.test("e2e preview", () => runTest("preview"));
}

Reporting Format

• Examples: list of verified examples
• Build: pass/fail per example
• E2E Start: pass/fail per example
• E2E Preview: pass/fail per example
• Anomalies: console/request/pageerror summary
• Notes: expected skips or known caveats

Guardrails

• Do not rely only on build success; start/preview behavior must be observed.
• Do not use pnpm run ready unless the user explicitly asks for full CI parity.
• Do not edit generated dist/ files.
• Use the new standalone E2E runner (see scripts/test-e2e.mts) — vitest is no longer involved.
