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.

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.
