|
||||
The comparison of the contents of ``qs`` and ``values`` is performed using
|
||||
the function ``transform``; by default, this means that the ``repr()`` of
|
||||
each value is compared. Any other callable can be used if ``repr()`` doesn't
|
||||
provide a unique or helpful comparison.
|
||||
|
||||
The comparison is also ordering dependent. If ``qs`` doesn't provide an
|
||||
implicit ordering, you will need to apply a ``order_by()`` clause to your
|
||||
queryset to ensure that the test will pass reliably.
