``makefilefn`` is a callable which receives the test case as an

|
argument and returns an object implementing the ``ifilestorage`` interface.
|
|
|
|
|
|
``maketransactionfn`` is a callable which receives the test case as an
|
|
|
argument and returns a transaction object.
|
|
|
|
|
|
``addrawrevisionfn`` is a callable which receives arguments describing a
|
|
|
low-level revision to add. This callable allows the insertion of
|
|
|
potentially bad data into the store in order to facilitate testing.
|
|
|
|

|
Returns a type that is a ``unittest.TestCase`` that can be used for
|

testing the object implementing the file storage interface. Simply

assign the returned value to a module-level attribute and a test loader

should find and run it automatically.
