In the words of Django co-creator Jacob Kaplan-Moss34, “Code without tests is broken as designed.”Testing can be divided into two main categories: unit and integration. Unit tests check a piece of functionality in isolation, while Integration tests check multiple pieces linked together. Unit tests run faster and are easier to maintain since they focus on only a small piece of code. Integration tests are slower and harder to maintain since a failure doesn’t point you in the specific direction of cause.
