This assertion makes Puppetry to intercept HTTP requests. It compares the given limits to the encoded length of the requests. Note that the request length is considered `0` when request loaded from cache. So it makes sense to place this step next to the very first `page.goto` in the test suite. ![page.assertPerformanceAssetWeight](https://3461068122-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LdyKJ-zzeS2hB7DF04J%2F-LuCFgUq_YnWyw_Isc2v%2F-LuCHsENqomQr7BK4e0N%2Fpage.assertPerformanceWeight.png?alt=media\&token=89e6e1e2-fa92-4d8d-ba85-4dccc12a3897) ## page.assertPerformanceAssetCount Asserts that total number of requested assets (JavaScript, CSS, images, media, fonts, XHR) on the page satisfies the given budget. ![page.assertPerformanceAssetCount](https://3461068122-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LdyKJ-zzeS2hB7DF04J%2F-LuCFgUq_YnWyw_Isc2v%2F-LuCI9wLypFFWlj1OgZC%2Fpage.assertPerformanceCount.png?alt=media\&token=430f3a64-967e-487d-b066-09ca314c3a4f) ## page.assertPerformanceTiming Asserts a given [resource timing](https://w3c.github.io/perf-timing-primer/#resource-timing) under a provided budget ![page.assertPerformanceTiming](https://3461068122-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LdyKJ-zzeS2hB7DF04J%2F-LuCFgUq_YnWyw_Isc2v%2F-LuCIOaTiazTrGcMbedz%2Fpage.assertPerformaceTiming.png?alt=media\&token=e3f8855f-098e-4f98-aea0-904f8783b258) ## page.assertGaTracking Asserts a given action was sent to Google Analytics with [analytics.js](https://developers.google.com/analytics/devguides/collection/analyticsjs) or [gtag.js](https://developers.google.com/analytics/devguides/collection/gtagjs). We also assert that sent payloads are valid according to the Google API ![page.assertGaTracking](https://3461068122-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LdyKJ-zzeS2hB7DF04J%2F-LuCFgUq_YnWyw_Isc2v%2F-LuCI_wv4zJat1WOhk8R%2Fpage.assertGaTracking.png?alt=media\&token=835a0306-4152-4d97-a9b1-c74f77b278c0) --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.puppetry.app/test-step/page-assertions.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
