Integration tests
Integration tests are automated tests that verify the correctness of integrations between the individual units of your services and the services themselves. In this section, you are going to learn how to write integration tests and how to structure the logic inside them, as well as get some useful tips that will help you write your own integration tests in the future.
Unlike unit tests that test the individual pieces of code, such as functions and structures, integration tests help ensure that the combinations of individual pieces still work well together.
Let’s provide an example of an integration test, taking our rating service as an example.
