What I mean is, can we replace mock_report_sender_ with new MockReportSender() ?

[stefanocs, 2016/06/09 06:41:29]

I was trying to do this earlier but I figured the report sender still need to be
accessed by the tests. If we remove the mock report sender as the member of this
class, we can still access the report sender from
permission_reporter_->permission_report_sender_ but I'm not sure how to cast
that into MockReportSender without moving the ownership from PermissionReporter
class.

Oh sorry, I understand now. This seems ok to me. See comment below.

Acknowledged.

Add a comment about the ownership of this:
// Owned by |permission_reporter_|.

[stefanocs, 2016/06/09 07:50:45]

Done.
