Answer:
1. Functional testing based on requirements with no knowledge of the internal program structure or data. Also known as closed-box testing.
2. Black box testing indicates whether or not a program meets required specifications by spotting faults of omission -- places where the specification is not fulfilled.
3. Black-box testing relies on the specification of the system or the component that is being tested to derive test cases. The system is a black-box whose behavior can only be determined by studying its inputs and the related outputs
4. Black box testing is functional testing, not based on any knowledge of internal software design or code. Black box testing are based on requirements and functionality.
