What is the Go testing framework and how do I use it?

The Go testing framework is a built-in package in Go that allows you to write unit tests for your code. You can use the testing package to create test functions that check the behavior of your code.

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

Sure! Here's a simple 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, but got %d", result)
    }
}

This code defines a function Add and a test function TestAdd that checks if Add(1, 2) returns 3.

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

You can run your tests using the command go test in the terminal. Make sure you're in the directory where your test files are located.

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 from each other.
