The order of the assertion should be expected, userResult.

Please, add some notes/comments that if there's any space at the end of each line, they should be trimmed

Why is the result must be ended with \n (new-line)?

There's no explanation as to what to do when the number is below 1, yet you add it to the test cases
The only explanation you have is this:

There will always be a design: /\ is the smallest/default.

Which is ambiguous since there's no explanation what's the "smallest" input.

All values higher than 100 default to 100

You don't even have any tests that the input goes beyond 100, why adding this?
