I don't think this is going to work very well on Windows.  You should use the
PathService and pass FilePath to TestOnUpdateStateWithFile.

+  EXPECT_EQ(0, process()->bad_msg_count());
+  test_rvh()->TestOnUpdateStateWithFile(id, file_name);
+  EXPECT_EQ(1, process()->bad_msg_count());

+  ChildProcessSecurityPolicyImpl* policy =
+      ChildProcessSecurityPolicyImpl::GetInstance();
+  policy->GrantPermissionsForFile(id, base::FilePath::FromUTF8Unsafe(file_name),
