Course Introduction：Key points of mock object unit testing A mock object is a substitute used in unit tests to replace the real object, simulating the running behavior of the real object. Simulating objects is useful when the dependencies of an object are not implemented yet or depend on factors that are difficult to simulate. In testing, mock objects are created and injected into the system to satisfy dependencies, allowing developers to start writing business logic. While hand-crafted mock objects can be used initially, as testing requirements become more complex, a real mock framework may be required. Simulation frameworks can save time and produce cleaner code. PHPUnit's mock framework is such a tool that can be used to create mock objects for testing. This process involves identifying the object to be simulated and defining the method to be simulated

Course Introduction：While not everyone is doing this, testing your application is one of the most basic parts of being a developer. Unit testing is the most common test. With unit testing, you can check if a class is running exactly as you expected. Sometimes, you are using third-party services in your application, and it's hard to set up everything for unit testing. This is when the simulation comes into play. Key Points Mocking is the process of creating a substitute for real objects in a unit test, which is especially useful when testing applications that rely heavily on dependency injection. Mockery is a library created by Pádraic Brady that can be used to mock objects in unit tests and is the default mock of PHPUnit

Course Introduction：Dependency Injection Container (DIC) is a tool that manages and provides object dependencies for use in PHP projects. The main benefits of DIC include: 1. Decoupling, making components independent, and the code is easy to maintain and test; 2. Flexibility, easy to replace or modify dependencies; 3. Testability, convenient for injecting mock objects for unit testing.

Course Introduction：In PHP unit tests, mocking is used to verify interaction behavior, and stubbing is used to predefined return values. 1. Mocking creates a mock object and sets the expectation of method calls, such as verifying whether the method is called once and whether the parameters are correct; 2. Stubbing sets the fixed return value of the method, and does not pay attention to the call method, which is suitable for state-based testing; 3. PHPUnit supports both through getMockBuilder(), which can be used alone or in combination to achieve fast and reliable unit testing.

Course Introduction：Go is a new language, a concurrent, garbage-collected, fast-compiled language. It can compile a large Go program in a few seconds on a single computer. Go provides a model for software construction that makes dependency analysis easier and avoids most C-style include files and library headers. Go is a statically typed language, and its type system has no hierarchy. Therefore users do not need to spend time defining relationships between types, which feels more lightweight than typical object-oriented languages. Go is a completely garbage-collected language and provides basic support for concurrent execution and communication. By its design, Go is intended to provide a method for constructing system software on multi-core machines.
