And it is tested with inputs that would go trough all the code branches right?

Does it have an upper limit for the longest run, or all branches have to have the same duration? I'm asking because I am curious if the function execution time being a constant is part of the program working correctly (scheduling). Somewhat related to how early programs worked correctly for 4.77 MHz and faster clock on CPU would break the program https://en.wikipedia.org/wiki/Turbo_button

I am working in free time on code for a controller that has to do time sensitive operations (actuate a solenoid/injector for a couple milliseconds) and I am thinking on how to correctly trigger the code so that the timing is accurate.
