What are the characteristics of Mock Objects and Stubs mentioned in the text?

Both are used for debugging purposes only
Mock Objects are lightweight and self-testing, whereas Stubs are heavyweight and often reused
Stub methods always return null, while Mock Objects can return real data
Mock Objects simulate exceptions, while Stubs simulate successful method calls

The correct answer is: Mock Objects are lightweight and self-testing, whereas Stubs are heavyweight and often reused

Mock Objects and Stubs are both techniques used for testing and debugging code, but they differ in terms of their characteristics. Option A is incorrect because while both are used for debugging purposes, this is not their only purpose. Option C is incorrect because while Stub methods usually return null, they can sometimes be programmed to return other values. Option D is incorrect because both Mock Objects and Stubs can simulate both successful and unsuccessful method calls. Option B is the correct answer because it accurately describes the main differences between Mock Objects and Stubs.
