Your question is Testing Before Deployment. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
How do you approach testing and validating your code before deployment? Explain how you select testing levels, validate behavior and edge cases, use automation, and decide whether the code is ready to release. Address how you handle defects, incomplete coverage, and risk during the final review.
