Is it a case of testing it and replacing it when required or do you prefer to work to a schedule changing the brake fluid regularly?

How often should brake fluid be changed or checked?

In 44 years of driving I have never changed brake fluid other than when repairing or modifying.

I like to partly flush mine after every 2 or so track days just to keep fresh fluid at the hot /caliper end and to double check if there is and air in the system for peace of mind.

it does depend on the brake fluid. Some brake fluids with higher boiling points do need changing more often .
bearing in mind the cost of fluid and the cost of discs and calipers and how important brakes are it isnt a cost issue for me so I do change it more often than most in the stagea.
And I change it all. i use ATE which is available in two colours so I dont waste fluid when changing it.
but for my daily driver normal fluid is fine and it isnt changed very often
