What is Go testing and how can I implement it in my project?

Go testing refers to the practice of writing tests for Go programs to ensure code quality and functionality. You can implement it using the built-in testing package.

Can you show me a simple example of a test in Go?

Sure! Here's a basic example:

package main

import "testing"

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

func TestAdd(t *testing.T) {
    result := Add(1, 2)
    if result != 3 {
        t.Errorf("Expected 3, got %d", result)
    }
}

This tests the Add function.

How do I run the tests once I've written them?

You can run your tests by using the command go test in your terminal. It will automatically find and execute all tests in your package.

What are some best practices for writing tests in Go?

Some best practices include writing clear and concise test cases, using table-driven tests for multiple scenarios, and keeping your tests independent.
