Lightweight mocks reduce overhead and improve test performance. They allow for faster execution and easier debugging, making your tests more efficient.
How do I create a mock for a complex component?
For complex components, start by identifying the key interactions. Use a mocking library to simulate these interactions while keeping the mock simple and focused.
