Could you please also remove this method and move the body of it into the
lambda?

[hub, 2017/04/21 18:37:28]

Done

[sergei, 2017/04/21 17:57:38]

Not sure whether we need that check.

[hub, 2017/04/21 18:37:28]

Removed.

here it should stay ASSERT because if the pointer is nullptr then we should not
continue the execution of the test.

[hub, 2017/04/21 18:37:28]

Changing this and elsewhere it applies.
