How can I handle errors in my Go API tests?

In Go, you can handle errors in your API tests by using the built-in error type. You should check for errors after each API call and assert that the expected error matches the actual error.

Can you give me an example of how to do that?

Sure! You can use the http package to make requests and check the response. For example:

resp, err := http.Get("http://example.com/api")
if err != nil {
    t.Fatalf("Error making request: %v", err)
}
if resp.StatusCode != http.StatusOK {
    t.Errorf("Expected status 200, got %d", resp.StatusCode)
}

This checks for errors in the request and verifies the response status.

What if I want to test for specific error messages?

You can compare the error message returned by your API with the expected message. For example:

if err != nil {
    if err.Error() != "expected error message" {
        t.Errorf("Expected error message, got: %s", err.Error())
    }
}
