Integration Testing: Testing that different parts of a system work correctly together, such as your API with the real database.
Example
An integration test checks that saving an order through the API actually stores it in the database.
Why Integration Testing matters for IT interns
Code can pass its unit tests and still fail once it is connected to other parts.
Where you will hear it
