As bug #1477199 describes, the wrong comment below is all over the
unit test code of OSC.
# DisplayCommandBase.take_action() returns two tuples
There is no such class named DisplayCommandBase in OSC. It is in cliff.
All OSC command classes inherit from the base classes in cliff,
class Command, class Lister and class ShowOne. It is like this:
Object
|--> Command
|--> DisplayCommandBase
|--> Lister
|--> ShowOne
take_action() is an abstract method of class Command, and generally is
overwritten by subclasses.
* Command.take_action() returns nothing.
* Lister.take_action() returns a tuple which contains a tuple of
columns and a generator used to generate the data.
* ShowOne.take_action() returns an iterator which contains a tuple
of columns and a tuple of data
So, this problem should be fixed in 3 steps:
1. Remove all DisplayCommandBase comments for tests of classes
inheriting from class Command in cliff as it returns nothing.
2. Fix all DisplayCommandBase comments for tests of classes
inheriting from class Lister in cliff. Lister.take_action()
returns a tuple and a generator.
3. Fix all DisplayCommandBase comments for tests of classes
inheriting from class ShowOne in cliff. ShowOne.take_action()
returns two tuples.
This patch finishes step 3 in compute tests.
