TestPull unit test should not perform functional verification. The purpose of
cmd unit tests should be testing proper cmd object creation, not actually run
the command. Moreover, we don't have possibility to mock and track all the
objects that created inside of called functions. We can only verify golden output
with help or when command performs basic stuff just inside of RunE interface. Actual
test of called methods performed in pkg module.
