Answer
Overusing mocks can lead to tests that are tightly coupled to implementation details.
When too many mocks are used, tests may fail even with minor changes to the code, as they depend on specific method calls or interactions. This makes refactoring difficult and can lead to false positives. For example, if every method in a shopping cart class is mocked, changes to internal logic might require updating multiple test cases unnecessarily.
