When should I use integration testing in ASP.NET Core?

Integration testing in ASP.NET Core is essential when you want to verify that different components of your application work together as expected. It's particularly useful after making changes to your code or when adding new features.

Can you give me some examples of when to perform integration tests?

Sure! You should perform integration tests when:

1. You integrate a new service or API.
2. You modify existing functionality that interacts with other components.
3. You want to ensure that your database interactions are working correctly.

How do integration tests differ from unit tests?

Integration tests focus on the interaction between components, while unit tests isolate individual components to test their functionality. Integration tests check if the components work together correctly, whereas unit tests ensure that each component behaves as expected in isolation.

What tools can I use for integration testing in ASP.NET Core?

You can use tools like xUnit, NUnit, or MSTest for writing integration tests in ASP.NET Core. Additionally, libraries like Moq can help with mocking dependencies.
