Your question is Frontend Testing Strategy. 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).
Describe different types of frontend testing (unit, integration, E2E) and when to use them.
Explain what each level validates, how the levels complement one another, and how you would balance confidence, execution speed, and maintenance cost. Include examples from a frontend application such as Agoda’s booking flow where useful.
