I don't believe this is needed.  If it is, should get rid of the forward
declaration.

It is required; scoped_ptr needs to know how to delete DnsClient, which it can't
find out from a forward declaration.

+#include "net/dns/dns_test_util.h"
+
+namespace net {
+class DnsClient;
+}
+
+namespace chrome_browser_net {
+
+// Creates a mock DNS client with a single rule for the known-good query
+// (currently google.com) that returns |good_result|.
+scoped_ptr<net::DnsClient> CreateMockDnsClientForProbes(
+    net::MockDnsClientRule::Result good_result);
+
+}  // namespace chrome_browser_net
+
+#endif
