Assistive technology testing

Testing a product with the actual tools people use, such as a screen reader, magnifier, switch, or voice control.

Assistive technology testing means using the real tools, not a simulation: a screen reader such as NVDA, JAWS, VoiceOver, or TalkBack; a screen magnifier; voice control; a switch. The tester completes real tasks, such as finding a product and buying it, and notes where the tool fails, what it announces, and whether the task can be finished at all.

It matters because the same page can behave differently in each combination of browser and assistive technology, and because a page can pass every automated check and still be unusable. An evaluation needs to say which tools and browsers were used, so the results can be repeated. Testing with the people who use these tools every day, through usability testing, is the next step up.
