Quick Answer
The browser compatibility test tool on the run page performs environment validation in one client-side session. Configure probe scope, filter by graphics, media, or APIs, and export a capability report with pass/fail rows for deployment analysis.
Formula
Readiness Score = (Passed Probes ÷ Total Probes in Scope) × 100
Introduction
This article is part of Browser Compatibilty Test WebGL, WebGPU, codecs, APIs. Open the compatibility test tool to validate WebGL, WebGPU, codec, and API readiness in your current browser.
The browser compatibility test tool delivers readiness scores, capability reports, compatibility assessment, and deployment analysis through client-side environment validation.
Overview
The browser compatibility test tool on the run page performs environment validation in one client-side session. Configure probe scope, filter by graphics, media, or APIs, and export a capability report with pass/fail rows for deployment analysis.
The browser compatibility test tool delivers readiness scores, capability reports, compatibility assessment, and deployment analysis through client-side environment validation.
Readiness scores summarize pass rates for your selected scope. Never compare scores across different scopes or category filters.
All processing stays local. Exports remain on your device until you share them with QA, support, or release reviewers.
Reference documentation describes what browsers are supposed to support. The tool reports what the browser in front of you supports now, including driver quirks and policy blocks tables never capture.
If you are new to readiness workflows, read can my browser run this web app first so probe scope, category filters, and scoring make sense before you interpret results.
After each run, archive output as a browser support readiness report beside your release tag so regressions become visible when a dependency upgrade silently drops support on a target platform.
- ●Readiness score from live probe pass rates
- ●Capability report with category-filtered rows
- ●Compatibility assessment for release planning
- ●Deployment analysis exports in JSON or text
Probe Scope, Filters, and Release Gates
Quick scope suits daily developer checks. Standard scope fits most release gates. Full scope adds advanced codecs and hardware-adjacent APIs for comprehensive deployment validation.
Live metrics during a run show WebGL version, WebGPU adapter status, codec pass counts, and API tallies so you can spot subsystem failures before the full suite completes.
Category filters help when a user reports video issues but graphics probes still pass, or when API rows fail while codecs look healthy on the same session.
Key Formula
Category filters isolate graphics, media, or API failures during debugging without rerunning unrelated probes.
One failed critical row can block a feature even when the headline score looks acceptable. Read individual rows, not just the score.
Live metrics during the run show subsystem summaries before the full suite completes, which helps you abort early when a critical graphics row fails on the first probe.
When scores drop after a browser update, review failed rows by category and attach exports to the release ticket before deciding whether to hold the deploy.
Readiness Score = (Passed Probes ÷ Total Probes in Scope) × 100
- ●Use consistent probe definitions across browsers
- ●Weight critical rows by product impact
- ●Re-run after browser or driver updates
Step by Step
Walk through these steps the first time you use the tool for release documentation, then repeat with locked scope whenever you compare browsers.
-
1
Open the run page
Navigate to the compatibility test tool and review scope and filter options.
-
2
Configure probe menu
Select quick, standard, or full scope and optional category filter.
-
3
Start validation
Run probes and watch pass/fail rows appear with live metrics.
-
4
Review readiness score
Check compatibility score alongside WebGL, WebGPU, codec, and API summaries.
-
5
Export capability report
Download JSON for diffing or text for stakeholder sharing.
Practical Examples
A mobile QA lead runs standard scope on Android WebView before each store submission. Codec rows frequently differ from desktop Chrome, preventing surprise playback failures.
When scores drop after a browser update, teams review failed rows by category and attach exports to the release ticket before deciding whether to hold the deploy.
A developer verifies WebGPU after enabling a browser flag. Adapter success confirms it is safe to test an experimental branch locally before enabling the path for beta users.
Support asks a user to run the tool and send JSON. Engineers see WebGL disabled by policy instead of an application defect, closing the ticket without a code change.
A streaming QA lead filters media-only probes when investigating codec complaints, isolating playback dependencies without rerunning the entire graphics and API suite.
- ●Save readiness exports with each support ticket
- ●Map failed rows to fallbacks or upgrade paths
- ●Review examples in release retrospectives
FAQ
- FAQDoes the tool upload results automatically?
- No. All probes run locally. You control when exports leave your device.
- FAQWhich scope should I use for release gates?
- Standard or full scope. Quick scope is for fast developer checks only.
- FAQCan I filter by subsystem?
- Yes. Limit runs to graphics, media, or APIs when debugging a specific layer.
- FAQHow is this different from cloud browser grids?
- Cloud grids host remote browsers. This tool validates the browser on the device in front of you.
- FAQCan support staff use the tool?
- Yes. The interface is designed for QA and support as well as developers.
- FAQWhich probe scope should I use?
- Quick for daily checks, standard for most release gates, full when you need advanced codecs and hardware-adjacent APIs in the archive.
- FAQCan I share exports with customers?
- Yes. JSON and text exports contain capability results only, with no account data, since probes run locally on the user's device.
Conclusion
The compatibility test tool turns deployment questions into structured readiness evidence on your machine.
Run it after OS upgrades, browser updates, or when customer reports do not match your default environment.
Make the tool part of your release ritual: run, export, diff against the prior version, and attach summaries to the ticket your release manager reviews.
