Welcome to your interview.
The question is on your right: Test Strategy for New Feature. 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're asked to test a new customer-facing feature before release. The feature is still evolving, and different partners may care about different outcomes, from core functionality to regression risk and release confidence.
How do you approach writing test cases for a new feature?
