Done.

nit: You shouldn't need to define the constructor/destructor

[stefanocs, 2016/06/09 05:56:12]

Done.

Done.

I actually don't think we need to test BuildReport (at least for now). I think
the SendReport test covers it.

[stefanocs, 2016/06/09 05:56:11]

Done.

nit: inline this to avoid dealing with a raw pointer

[stefanocs, 2016/06/09 05:56:12]

Do you mean it should be wrapped with unique_ptr?

+  PermissionReporter permission_reporter(base::WrapUnique(mock_report_sender));
+  permission_reporter.SendReport(GURL(kDummyOrigin), kDummyPermission,
+                                 kDummyAction);
+
+  PermissionReport permission_report;
+  ASSERT_TRUE(
+      permission_report.ParseFromString(mock_report_sender->latest_report()));
+  EXPECT_EQ(kDummyProtobufPermission, permission_report.permission());
+  EXPECT_EQ(kDummyProtobufAction, permission_report.action());
+  EXPECT_EQ(kDummyOrigin, permission_report.origin());
+
+  EXPECT_EQ(GURL(kPermissionActionReportingUploadUrl),
+            mock_report_sender->latest_report_uri());
+}

+}  // namespace
