How do I set up a Go testing environment?

To set up a Go testing environment, you need to install Go, set up your workspace, and create test files.

What tools do I need for testing in Go?

You primarily need the Go toolchain, which includes the go test command, and optionally, testing frameworks like Testify.

Can you show me a simple test example?

Sure! Here's a simple test for a function that adds two numbers:

package main

import "testing"

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)
    }
}

Run it using go test.

How do I run my tests?

You can run your tests by navigating to your package directory in the terminal and executing the command go test. This will automatically find and run all test files.
