Course Introduction：The key to testing React components is to select the right tools and simulate user behavior for verification. 1. Use mainstream tools such as Jest and ReactTestingLibrary (RTL) to improve interaction authenticity with user-event; 2. When writing unit tests, render components through render, query nodes with screen and assert results; 3. Use fireEvent or userEvent to simulate clicks, input and other operations to verify state changes; 4. Snapshot testing is suitable for change detection of static UI structures, but cannot replace behavioral testing. These methods can effectively improve the stability and maintainability of components.

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.
