Integration Testing and Unit Testing are two commonly used testing methods in software development. They have the following differences: Scope: Unit testing is to test small testable units of software, usually a function, method or class. Encapsulation testing is the integration testing of multiple units or components to test their interaction and collaboration. Dependency: Unit testing usually uses simulation or virtual objects to replace other components on which the unit under test depends to isolate the unit under test. Encapsulation testing requires real components and dependencies to test to ensure the correctness of the entire system. Objective: The goal of unit testing is to verify whether the function of the unit is correct, usually focusing on the correctness of the input and output. The goal of encapsulation testing is to verify whether the integration between multiple units or components is correct, focusing on the interaction and collaboration between components. Isolation: Unit testing has a high isolation, which makes it easier to locate and fix problems. The isolation of packaging test is low, and more debugging and troubleshooting may be required. Execution order: Unit tests can be executed independently, independent of other tests or environments. Encapsulation tests need to be performed in a specific order to ensure correct integration between components. In general, unit testing focuses more on the function and correctness of a single component, while packaging testing focuses more on the integration and collaboration between multiple components. In actual software development, these two testing methods are usually used at the same time to ensure the quality and stability of software.
