It looks weird that we are only disabling PING for this single test. I think we
probably want to disable it for all tests by default. I think you should take
out all of these calls and move them into net/base/run_all_unittests.cc, and
then only enable it for the unit tests that specifically test PING.

Done.

   for (size_t i = 0; i < arraysize(kTests); ++i) {
     SessionDependencies session_deps(ProxyService::CreateDirect());
     scoped_refptr<HttpNetworkSession> session(CreateSession(&session_deps));
