Mocking dependencies with Moq
Testing frequently involves scenarios where our system under test interacts with external dependencies, whether they are databases, APIs, or other services. Running tests against these real dependencies can lead to slow, unpredictable outcomes and potentially unwanted side effects. Mocking provides a solution by simulating these dependencies, ensuring our tests focus purely on the component at hand. Through mocking, we gain control over external interactions, ensuring our tests are swift, reliable, and free from external influences.
Integration tests
When writing unit tests, we typically want to mock external dependencies as much as possible. However, it is often valuable to also test the integration of different components to ensure they work together seamlessly. This is where integration tests come in. Unlike unit tests, which focus heavily on mocking to test units in isolation, integration tests often involve fewer mocks. This ensures that components...
