Hybrid browser test results

Identify slow URLs and inspect page-load phases during a hybrid load test.

The Web Vitals tab highlights the most important frontend performance signals for your application during load. Use this page to identify slow URLs and compare key metrics across the site.

Worst-performing URLs

The Worst-performing URLs chart surfaces the top 5 URLs with the worst values for the selected metric. Use the toggle to switch between LCP, INP, CLS, FCP, and TTFB. Values represent the percentile selected in the report header (for example, p75) across all virtual users.

Use this view to decide which URLs to prioritize for optimization.

Detailed URL table

The Detailed URL table lists every tested URL with its Web Vitals values and a breakdown of page-load phases (for example, DNS, connect, request, response, render). Sort by any column or search by URL to narrow the list. A dash (-) in a cell means the metric was not captured for that URL.

The Tests tab lists every test case executed during the run, surfaces its outcome, and links the result back to the underlying test reporting and analytics record. Use this tab to confirm functional correctness under load and to triage any tests that did not pass.

What you can do here

On this tab, you can:

• Review the four status counts on every test case row: Passed, Failed, Skipped, and Other status (across virtual users).
• Search by test name to locate a specific test case.
• Filter the list with the All Tests dropdown, or sort by status (for example, Failed - High to Low) to bring the worst-performing tests to the top.
• Open the Details link on any row to inspect a single test’s failure profile.

Test status reference

The following table describes the possible test statuses you may see on the Tests tab:

Drill into a single test

Select Details on any test case row to open the per-test panel. The panel shows:

• Load vs Failure Rate Progression for that single test case: virtual users (actual load) plotted alongside the test failure rate against time, so you can correlate the test’s failures with the run’s load profile.
• Unique Errors captured for that test across all virtual users. If the test had no errors, the panel reports “No errors in the test”.

Use this view to confirm whether a failing test failed under specific load levels and to read the deduplicated error messages without leaving the tab.
