How do I set up testing in Go programming?

To set up testing in Go, you need to create a test file with a name ending in _test.go and use the testing package.

What functions do I need to include in my test file?

You should include functions that start with Test, like TestFunctionName, and use the *testing.T type to report test failures.

Can you show me an example of a simple test?

Sure! Here's a simple test for an Add function:

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

How do I run my tests once they're set up?

You can run your tests using the command go test in your terminal, and it will automatically find and execute your test functions.
