Screen reader compatibility
Expected Result: causes problems in some screen readers
Actual Result: causes problems in 64 screen reader / browser combinations
For expected failures, the results show which AT combos the failures affect. Results are recorded from the user's viewpoint, so describe the user impact of authoring errors.
Note: aria-describedby maps to the accessible description of an object, which is different to the accessible name generated from alt / aria-label / aria-labelledby.
Code used for this test:
<img src='1234.png' aria-describedby='img-aria-describedby-code'>
<span id='img-aria-describedby-code'>this is an aria described by</span>

Test notes
All tests were carried out with screen reader factory settings. JAWS in particular has a wide variety of settings controlling exactly what gets spoken.
Screen readers allow users to interact in different modes, and can produce very different results in each mode. The modes used in these tests are:
- Reading Content read using the “read next” command in a screen reader
- Tabbing Content read using the “tab” key in a screen reader
- Heading Content read using the “next heading” key in a screen reader
- Touch Content read when touching an area of screen on a mobile device
In the “What the user hears” column:
- Commas represent short pauses in screen reader voicing
- Full Stops represent places where voicing stops, and the “read next” or “tab” or “next heading” command is pressed again
- Ellipsis … represent a long pause in voicing
- (Brackets) represent voicing that requires a keystroke to hear
