Later on we will do integration tests which uses no mocks and tests the actual behavior of all components and their integration. This way we can control the behavior of our dependencies and test just the code we want to test. Mocks are objects that “fake”, or simulate, the real object behavior. Since we are doing unit tests, we need to isolate dependencies.Follow clear and consistent naming conventions.Code is more reliable and reusable because in order to make unit testing possible, modular programming is the standard technique used.Good unit tests may also serve as documentation for your software.Understanding the code base is essential and unit tests are some of the best way of enabling developers to learn all they can about the application and make changes quickly.They help to fix bugs early in the development cycle and save costs.Here are some key reasons to not skip the proccess of creating unit tests : Either way, unit tests are an important step in the development phase of an application. In the previous article we covered some testing strategies, which you can check it here.Ī unit is the smallest testable part of the software and in object-oriented programming it’s also called a method, which may belong to a super class, abstract class or a child class. In software development, testing each part of a program is crucial to assert that all individual parts are correct.
