There is a difference in that the stub uses state verification while the mock uses behavior verification. Overview. Mais cette définition est trop simpliste…. It is used when we cannot or … People say mock when they mean stub and vice versa. We use stubs if we want to: 1. control individual method behavior for a specific test case, 2. prevent a method from making side effects like communicating with the outside world using Angular's HttpClient.
