hello! i was wondering how i would go about giving a

kotlin.test.assertEquals

a list of valid expected outputs, like can i just pass it a list and if the output of whatever im testing is part of that list itll say the test passed?

No, a list is not equal to one of its members, that wouldn't really make much sense

I believe the problem is to accept the output if it is a valid subset of the list of expected outputs. eg: expectedOutput = [ 1, 2, 3, 4, 5] resultOutput = [ 3, 4 ] In such a case, one would want the test to pass. If that is the problem statement, one quick way to do it would be to

assertEquals (expectedOutput.intersect(resultOutput), resultOutput, "Expected $resultOutput to be a subset of $expectedOutput" )

Even if that would be the case (which I doubt) I think

assertTrue

would be better. There is no need to do a full intersect when you just want to know whether one list contains the other. So it should be

assertTrue(expectedOutput.containsAll(resultOutput), "my message")

which can abort as soon as it found a discrepancy. Or in the case how I understood it

assertTrue(expectedOutput.contains(resultOutput), "my message")

Thanks for the help guys! What i intended to ask originally was how to check if the output(a single int) was part of a list of valid answers, assertTrue works for what i need.

Yes, that's what I thought any my last line shows 🙂

If this is a case that comes up often in your testing,

assertContains

and

assertContainsAll

with automatic error messages are likely worthwhile functions to create.
