proxy/proxy_test.go:40–63

isCachedWithCustomConfig is a helper function that returns the caching results of a constructed request using the provided custom upstream configuration and FQDN.

(
	tb testing.TB,
	p *proxy.Proxy,
	conf *proxy.CustomUpstreamConfig,
	fqdn string,
)

// results of a constructed request using the provided custom upstream
// configuration and FQDN.

	d := &proxy.DNSContext{

		Req:                  (&dns.Msg{}).SetQuestion(fqdn, dns.TypeA),
	}
