According to the text, how can one differentiate between a Mock Object and a Stub?

  1. By the method names used in each

  2. By their usage in unit tests versus integration tests

  3. By the depth of functionality and reuse pattern

  4. By the programming language they are implemented in

The correct answer is: By the depth of functionality and reuse pattern

Using the context provided in the text, one can differentiate between a Mock Object and a Stub based on their depth of functionality and reuse pattern. A Mock Object is designed to mimic the behavior of a real object and closely replicates its functionality, whereas a Stub is designed to provide generic, predetermined responses and has limited functionality. Therefore, the depth of functionality and reuse pattern is a key factor in distinguishing between a Mock Object and a Stub. The other options are incorrect because method names can be similar in both a Mock Object and a Stub, they can both be used in unit and integration tests, and they can be implemented in any programming language. However, the key difference lies in the extent of functionality and reuse pattern.
