how do other people do tests that involve suspending functions?
in my karma test which i run in a GlobalScope.launch i see no log output at all
if i use promise see all logs in a single line.. but the assertion seem to work.. somewhat

I had the same issue. I replaced Karma by Mocha and now I can see all the lines fine. No idea why Karma doesn't work though

[Nikky]

mocha is not a option because then the app does not run.. and testing goes nowhere then either
something about window not defined or such

You have to make sure the promise is returned by the test function, so its kind of tricky to do straight out of the box

[Rob Murdock]

if you write a test like:

@Test
fun willOrganizeTestNicely() = GlobalScope.promise {
//test code here
}

the test will wait until the promise resolves before its done. When you don’t return a promise, you run the risk of the test “finishing” before the work is actually completed

I had to figure out all this nonsense in order to make a coroutines-compatible version of my library “testmints”, and I think it works pretty well. Could be some useful lessons in the source if you’re curious.

AFAIK that works for both karma and mocha. And jasmine (I do some test running outside of the default tasks as well).
