In a software system, components rarely operate in isolation; rather, they interact with one another to successfully complete their functions. During the process of unit testing, it is often deemed unnecessary to engage the actual implementations of these interconnected components, as there is typically a level of trust in their stability. Instead, mock objects are utilized as substitutes for the collaborators related to the unit under examination. To thoroughly assess a unit in isolation and to establish a suitable testing environment, it is crucial to mimic the behavior of these collaborators within the testing framework. A Mock Object serves as a test-oriented replacement for a collaborator, crafted to emulate the capabilities of the original object in a straightforward manner. Unlike a stub, which simply returns fixed responses, a Mock Object not only provides these responses but also verifies its correct usage throughout the testing procedure.
