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.
