Missed it in a version of docs I prepared couple year ago. Needs to 
be added.

No. It's intended for end user.

Yes.

None of the test units are going to be executed. They are going to 
be reported as skipped.

No.

For the test units registered in different test files there is no order. 
For the test units with the same test file the order will be "natural" 
from top to bottom.

In the order you registered.

All dependencies should pass for the test unit to be executed.
