== Test filtering
It’s a common requirement to run subsets of a test suite, such as when you’re fixing a bug or developing a new test case.
Gradle provides filtering to do this.
You can select tests to run based on:

		// In this scenario it should be determined by exact lookup.
		if !hIsWildCarded && !importedHost.IsWildCarded() {
			continue
		}
		// Check if the hostnames match per usual hostname matching rules
		if h.SubsetOf(importedHost) {
			return true
		}
	}
	return false
}

// VSMatches checks if the hostClassification(sidecar egress hosts) matches the VirtualService's host
