What is the difference between integration tests and unit tests?

What is the difference between integration tests and unit tests?

Unit tests focus on individual components or functions, while integration tests evaluate how those components work together.

Can you give me an example of each type of test?

Sure! A unit test might check if a function returns the correct output for given inputs. An integration test could verify that a user can log in and access their profile after authentication.

When should I use integration tests over unit tests?

Use integration tests when you need to ensure that multiple components work together correctly, especially in complex systems.

Are there any tools you recommend for writing these tests?

Yes! For unit tests, you can use frameworks like JUnit for Java or pytest for Python. For integration tests, tools like Postman or Selenium are great options.
