# Testing Events: startup - shutdown

When you need your event handlers (`startup` and `shutdown`) to run in your tests, you can use the `TestClient` with a `with` statement:

```Python hl_lines="9-12  20-24"
{!../../docs_src/app_testing/tutorial003.py!}

	"Network Authentication Required": http.StatusNetworkAuthenticationRequired,
}

// StatusCode returns a HTTP Status code for the HTTP text. It returns -1
// if the text is unknown.
func StatusCode(text string) int {
	if code, ok := statusTextToCode[text]; ok {
		return code
	}
	return -1
}

func fwdHeadersToS3(h http.Header, w http.ResponseWriter) {
	const trim = "x-amz-fwd-header-"
