Hehe, I'll add it to my TODO list right after: write a code-generator that parses the devices xmls and generates source files with constants and monkey.jungle file is a useflul way :)

Write a code generator that creates 256 test functions /s

Yes, but I don't see how that's related. I already use mocks (not in the conventional way though), but what I was looking for is how to have 256 tests instead of 1. Currently I have 1 test that loops over the numbers 0..255 and fails at the 1st one that fails the function I test, but I'd like to see all the numbers when it fails. In another language this would looks something like:

(:dataProvider)
function dataProvider() as Array<Number> {
return [0,1,2,3,...255];
}

(:testWithDataProvider(:dataProvider))
function test(hr as Number) as Boolean {
// use hr
return true or false;
}

so test would be called with each value, and I would see each of the failing values in one run.

did you read the tutorial? it has a whole section about mocking ;)

Yeah, I'm the last to claim that anything in Monkey C makes sense to me. ¯\_(ツ)_/¯

Glad it's working for you now.

It would've make more sense to have the test function next to the private function I wanted to test, and according to the docs it should have worked if they are static. But I copied it to global and now it works.

I have one problem though:

I have a whole tutorial on my website on how I set up unit tests, the tutorial talks about eclipse, but the concept still stands in vs code.

tutorials 4-6 apply, read them in order. 🙂

Not sure why you're getting that type error, but you don't want to define a test class, you want to define (global) test functions:

This works fine for me:

import Toybox.Test;

(:test) function testFoo(logger as Logger) {
    logger.warning("warning");
    logger.debug("debug");
    logger.error("error");
    return 42 == 42;
}

------------------------------------------------------------------------------
Executing test testFoo...
WARNING (21:33): warning
DEBUG (21:33): debug
ERROR (21:33): error
PASS
