      "import { browser } from 'k6/browser';\n\nexport const options = {\n  scenarios: { ui: { executor: 'shared-iterations', options: { browser: { type: 'chromium' } } } },\n};\n\nexport default async function () {\n  const page = await browser.newPage();\n  try {\n    await page.goto('<first-url>');\n    await page.goto('<second-url>');\n    await page.goBack({ timeout: 30000, waitUntil: 'load' });\n    await page.goForward();\n  } finally {\n    await page.close();\n  }\n}"

    "gotchas": [
      "Version: v1.6.0",
      "options: Options object for the history navigation call; defaults to null.",
      "options.timeout: Maximum operation time in milliseconds; defaults to 30000. Set to 0 to disable the timeout.",
      "options.waitUntil: Navigation success event; defaults to `load`. Allowed values: `domcontentloaded`, `load`, `networkidle`. Docs caution that `networkidle` may never fire on busy sites.",
      "Prerequisite: A browser scenario must specify an executor and set `options.browser.type` to `chromium`.",
      "Prerequisite: Install k6 and a Chromium-based browser, or use a Docker image with Chromium built in.",
      "The methods support optional timeout and `waitUntil` parameters."
