1. Self-built method "==", case-sensitive, the simplest method
fmt.Println("go"=="go") fmt.Println("GO"=="go")
Output result:
true false
2. Compare Function, case-sensitive, faster than the self-built method "=="
fmt.Println(strings.Compare("GO","go")) fmt.Println(strings.Compare("go","go"))
Output result:
-1 0
3. Compare UTF-8 encoding under lowercase conditions Whether they are equal or not, case-insensitive
fmt.Println(strings.EqualFold("GO","go"))
Output result:
true

The reason for using interfaces for simulation and testing is that the interface allows the definition of contracts without specifying implementations, making the tests more isolated and easy to maintain. 1) Implicit implementation of the interface makes it simple to create mock objects, which can replace real implementations in testing. 2) Using interfaces can easily replace the real implementation of the service in unit tests, reducing test complexity and time. 3) The flexibility provided by the interface allows for changes in simulated behavior for different test cases. 4) Interfaces help design testable code from the beginning, improving the modularity and maintainability of the code.

In Go, the init function is used for package initialization. 1) The init function is automatically called when package initialization, and is suitable for initializing global variables, setting connections and loading configuration files. 2) There can be multiple init functions that can be executed in file order. 3) When using it, the execution order, test difficulty and performance impact should be considered. 4) It is recommended to reduce side effects, use dependency injection and delay initialization to optimize the use of init functions.
