Note that after honing and using knives repeatedly in similar situations, you will start to learn when the knife is honed to the finest edge without testing. The way the knife feels against the steel tells you where it is in the honing process, once you've learned how that changes with sharpness. And also you can learn to feel the sharpness with a thumb, but it's hard to describe what it feels like - you just have to feel it and then try using the knife and then remember which feelings match with more sharpness. At home the ultimate test is a ripe tomato (IMHO).

Try to slice a piece of paper. A good sharp knife makes a clean cut. A dull knife makes either a ragged cut, or worse, just pushes the paper to the side. I like this article: https://www.fieldandstream.com/articles/hunting/2014/08/paper-cut-testing-blade-sharpness#page-4 and YouTube is full of videos of people showing off their knives via this test.

The back of a fingernail can be a good rough indicator while you're sharpening - see if it "catches" when you apply very gentle pressure at ~45 degree angle. This can also be a good way to check if the edge still has any dull spots.

You hold it edge up and then you let a silk scarf slowly float down over it. It should be cut neatly in half.

the best test for if your knife is sharp enough is to place it in a stream with the water flowing over the blade. If your knife is sharp, leaves and fish that flow past it will be cut, but if it's the sharpest, then only leaves will be cut but fish will be okay.
