Sorry for the late notice, I had missed this patch set. You can now replace
lines 488-496 with:
TryToRegisterSuccessfully("1-0" /* expected_push_registration_id */);

+  ASSERT_EQ("ok - service worker registered", script_result);
+
+  InfoBarResponder accepting_responder(browser(), true);
+  ASSERT_TRUE(RunScript("requestNotificationPermission();", &script_result));
+  EXPECT_EQ("permission status - granted", script_result);
+
+  ASSERT_TRUE(RunScript("registerPush()", &script_result));
+  EXPECT_EQ(std::string(kPushMessagingEndpoint) + " - 1-0", script_result);
+
+  gcm_service()->AddExpectedUnregisterResponse(GCMClient::SUCCESS);
+
+  ASSERT_TRUE(RunScript("unregister()", &script_result));
+  EXPECT_EQ("unregister result: true", script_result);
+}
+
+IN_PROC_BROWSER_TEST_F(PushMessagingBrowserTest, UnregisterNetworkError) {
+  std::string script_result;
+
+  ASSERT_TRUE(RunScript("registerServiceWorker()", &script_result));

Same here.

+  ASSERT_TRUE(RunScript("unregister()", &script_result));
+  EXPECT_EQ("unregister error: "
