Question

What is the difference between bottom-up testing and top-down testing?

a.

Bottom-up testing is a method where low-level components are tested first and top-down testing is a method where top-level components are tested first

b.

Bottom-up testing is a method where top-level components are tested first and top-down testing is a method where low-level components are tested first

c.

Both methods test the system as a whole

d.

Both methods test the individual components

Answer: (a).Bottom-up testing is a method where low-level components are tested first and top-down testing is a method where top-level components are tested first Explanation:Bottom-up testing is a method where low-level components are tested first and integrated with components at the next higher level. On the other hand, top-down testing is a method where the top-level components are tested first and are gradually integrated with lower-level components.
