How to test
Timing
Users work at different speeds and some can't rush. Test that time limits can be extended or turned off, and that anything moving, blinking, or auto-updating can be paused.
What to test
- Time limits can be turned off, adjusted, or extended before they expire.
- Session-timeout warnings appear with enough time and a clear way to continue.
- Moving/blinking/scrolling content lasting over 5s can be paused, stopped, or hidden.
- Auto-updating content (feeds, carousels, tickers) can be paused or controlled.
- Nothing flashes more than three times per second.
- Re-authenticating after a timeout doesn't lose the user's data.
How to test
- 1Find any countdown or session timeout and confirm you can extend or disable it.
- 2Leave an auto-advancing carousel or marquee running and confirm a visible control stops it.
- 3Confirm pausing persists — it must not silently restart.
- 4Review any flashing content against the three-flashes-per-second threshold.
Common failures
- A session that logs out with no warning and no way to extend.
- An auto-rotating carousel with no pause or stop control.
- A ticker or animation that runs indefinitely with no control.
- Re-login that discards a half-completed form.
- Content flashing more than three times a second.
