Given that JAWS is pretty pricey and has a steep learning curve I have mostly been focussing on getting everything running well on NVDA and VoiceOver and getting support from other members of the team to check JAWS.
For the past 8 years I have been working on a Mac. Whilst there is VoiceOver for Mac (which is not the same as VoiceOver on iOS) NVDA is not available and only runs on Windows.

Now you can use a browser and see how it is read by NVDA.
Optional extra - Getting NVDA to read multiple languages correctly
- With NVDA running you can right click on it running in the task bar and select
- Under the
Speechsection you need to set the
