How do you ensure quality and best practices in your work?.

To ensure code quality and adhere to best practices in Golang, I use several approaches:

• Code review: an essential step before merging changes, helps identify errors and improve architecture.
• Unit tests and integration tests: I cover critical parts of the code with tests to guarantee correct operation.
• Static analysis and linters: I use tools like golint, go vet, staticcheck to identify potential issues.
• Profiling and monitoring: I utilize pprof and metrics to optimize performance.
• Following Go idioms: I adhere to the official style and recommendations to make the code understandable and maintainable.

Example of a simple test in Go:

func Add(a, b int) int {
    return a + b
}

func TestAdd(t *testing.T) {
    result := Add(2, 3)
    if result != 5 {
        t.Errorf("Expected 5, got %d", result)
    }
}
