nit: SetUp()/TearDown() do just calling parent methods. Could you remove?

In common practice, parent's SetUp() should be called at first.
Could you comment why you need to run this before parent's SetUp()?

[khmel, 2017/01/31 15:25:22]

Moved down, this is not principal here. It is common in unit_tests to set flags
before calling base class.
