I was wondering what happens behind the scenes after I hand over my van?
Is just a visual check/ check with appropriate test equipment?
Do they take anything apart?

The test does have things that are visually inspected, steering joints shocks, lights for function and direction etc
But some things are physically tested such as the braking force on each wheel, balance across the axle, parking brake force. Also wipers and washers for function and on commercial trucks things like the AdBlue system are checked as well as tachographs.
They do not take things apart though, so they don't remove the head to check pistons etc.
You can ask - some places have a viewing window or area so you can see them doing the test but it does depend.
