About
Test your device. Test yourself.
Testpartout provides device diagnostics and human-performance tests that run in your browser. Check your hardware or measure how you interact with it, with a clear explanation of each test’s method and limits.
What Testpartout is
Testpartout has two main areas: device diagnostics for checking hardware behaviour, and Human Performance tests for measuring reaction, typing, clicking, memory and aim. Both use browser-based methods with practical explanations of what they can and cannot tell you.
The tagline is the product: “Test your device. Test yourself.” The same browser session holds both the instrument and the subject, and Testpartout treats both honestly.
Browser-based testing philosophy
Every test runs locally in your browser using standard web APIs. There is nothing to install and nothing to configure. This makes the tests instantly accessible anywhere, and it also defines their limits: a browser measurement reflects your browser, your device, your display and your input hardware at that moment — not laboratory conditions.
Each test page documents how its measurement works and where its limits are, so you can judge a number in context instead of trusting it blindly.
Tests available now
Explore the currently live device diagnostics and Human Performance tests below.
Device diagnostics
- Touch Screen TestMap touch coverage, compare simultaneous contacts and watch for unexpected touch events reported by your browser.
- Keyboard Ghosting & Key Rollover TestHold combinations together and compare browser-observed keys, presets and maximum simultaneous input.
- Mouse Polling Rate TestEstimate browser-delivered mouse event rate over ten seconds with median intervals and sample context.
- Monitor TestInspect manually selected colors, gradients, uniformity and geometry patterns without automatic defect claims.
- Microphone TestCheck that your microphone is detected and picking up sound, with a live input level meter.
- Speaker TestPlay left, right and reference tones to check each speaker is working, on the correct side and free of obvious distortion.
- Left / Right Headphone TestVerify stereo channels, wiring and balance by playing audio to the left and right sides separately.
- Webcam TestSee your camera feed, confirm the right device is selected and check framing before a call.
- Keyboard TestPress keys to confirm every one registers, and find stuck, dead or repeating keys.
- Mouse TestCheck buttons, double-clicks, scrolling and pointer movement for a failing or erratic mouse.
- Gamepad / Controller TestCheck buttons, triggers and analog sticks, including stick drift and dead-zone behaviour.
- Dead Pixel TestRun full-screen solid colours to reveal dead, stuck or discoloured pixels on your display.
- Screen Resolution TestSee the resolution, viewport size, pixel ratio and colour depth your browser reports.
- Refresh Rate TestEstimate the refresh rate your display is actually running at, with the limits of the method stated.
Human Performance
- Reaction Time TestMeasure how fast you respond to a visual cue, in milliseconds, across repeated attempts.
- Typing Speed TestWords per minute, accuracy and mistake patterns over a timed typing passage.
- Click Speed TestClicks per second over a fixed interval, with consistency across attempts.
- Visual Memory TestRecall increasingly complex patterns to measure your visual memory span.
- Sequence Memory TestRepeat growing sequences to find the longest order you can hold and recall.
- Aim / Accuracy TestHit targets under time pressure to measure accuracy, hits, misses and time-to-target.
Transparent methodology, honest numbers
A measurement without a method is just a number. Every Testpartout test page includes a methodology section describing what the code actually does, plus a list of the limits of a browser measurement. The same transparency extends to the platform level on the Methodology page.
Testpartout does not publish fabricated benchmarks, population averages or percentiles. Where no real aggregated data exists, no comparison is shown. Your results are your own measurements — not invented rankings.
Privacy-first by construction
Testpartout currently has no accounts and no test-result backend. Measurements are computed on your device and personal bests are kept in your browser's local storage — they are not uploaded. Checklists save only local statuses. Optional human-performance result cards are generated locally; sharing them with an external app happens only after your explicit choice. The details are described in plain language on the Privacy page, which states what the code does today rather than promising what a policy might say.
