it will create :class:`MarkInfo` objects which may be
|

:ref:`retrieved by hooks as item keywords <excontrolskip>`.
|
||||
MarkDecorator instances are often created like this::
|
||||
|
||||
mark1 = pytest.mark.NAME # simple MarkDecorator
|
||||
mark2 = pytest.mark.NAME(name1=value) # parametrized MarkDecorator

When a MarkDecorator instance is called it does the following:
|
||||
1. If called with a single class as its only positional argument and no
|
||||
additional keyword arguments, it attaches itself to the class so it
|
||||
gets applied automatically to all test cases found in that class.
|
||||
2. If called with a single function as its only positional argument and
|
||||
no additional keyword arguments, it attaches a MarkInfo object to the
|
||||
function, containing all the arguments already stored internally in
|
||||
the MarkDecorator.
|
||||
3. When called in any other case, it performs a 'fake construction' call,
|
||||
i.e. it returns a new MarkDecorator instance with the original
|
||||
MarkDecorator's content updated with the arguments passed to this
|
||||
call.
|
||||
|
||||
Note: The rules above prevent MarkDecorator objects from storing only a
|
||||
single function or class reference as their positional argument with no
|
||||
additional keyword or positional arguments.
