How do I handle errors in my Go tests?

In Go, you can handle errors in tests by using the 'error' return value. You should check if the error is nil and assert accordingly.

Can you give me an example of that?

Sure! Here's a simple example:

func TestMyFunction(t *testing.T) {
    result, err := MyFunction()
    if err != nil {
        t.Errorf("Expected no error, got %v", err)
    }
    // further assertions on result
}

What if I want to test for specific error types?

You can use type assertions to check for specific error types. For example:

if _, err := MyFunction(); err != nil {
    if _, ok := err.(*MyErrorType); ok {
        // handle specific error
    }
}

Are there any best practices for error handling in tests?

Yes! Always check for errors, use descriptive messages in your assertions, and consider using helper functions to reduce code duplication.
