Welcome to your interview.
The question is on your right: Complete Unit Test Logic. Take a moment with it first.
Talk your thinking through with me if you like - when you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes). Discussion and graded submissions share your five interviewer interactions, so spend them well.
You are given an incomplete unit test function. Complete the logic to properly validate the target function's output.
