### Writing controllers

Istio provides a few helper libraries to get started writing a controller. While these libraries help, there are still a lot of subtleties in correctly writing (and testing!) a controller properly.

func mustSelect(t test.Failer, selector map[string]string, labels map[string]string) {
	t.Helper()
	kselector := labels2.Set(selector).AsSelectorPreValidated()
	if !kselector.Matches(labels2.Set(labels)) {
		t.Fatalf("%v does not select %v", selector, labels)
	}
}

func mustNotSelect(t test.Failer, selector map[string]string, labels map[string]string) {
	t.Helper()
	kselector := labels2.Set(selector).AsSelectorPreValidated()
