One thing I find very useful when testing (or doing demos!) is to have VoiceOver's caption panel enabled. It shows constantly at the bottom of the screen and you can see exactly what VoiceOver is saying.

Please, don't use accessibility labels as ids for your UI tests. It can completely ruin the experience for VoiceOver users. There is actually an accessibility identifier property that you can use instead to uniquely identify your UI elements.
You should convey important information in multiple modes, not just color. If you are still required to do so, at the very least you should complement that info with other modes, like symbols, if the user requested differentiation without color.
Hacks are accessibility’s worst enemy. An example. There is a ‘trick’ floating on the internet: if you want a button with an icon to the right of the text, set the semantic content attribute to force right to left. Great way to create focus traps.
