Approved.

I see dependency failure related to com_googlesource_googleurl https://screenshot.googleplex.com/9sARYC2PcGcDMHH in the not required tests.

Approved.

I see dependency failure related to com_googlesource_googleurl https://screenshot.googleplex.com/9sARYC2PcGcDMHH in the not required tests.

That failure is expected since the ESPv2-API-regression-test runs the test at HEAD of master branch. https://github.com/GoogleCloudPlatform/esp-v2/blob/master/prow/gcpproxy-api-regression.sh#L58-L65
