    ''''Method decorator to add to your test methods.
    Should be added to methods of instances of ``unittest.TestCase``.
    ``value`` should be a path relative to the directory of the file
    containing the decorated ``unittest.TestCase``. The file
    should contain JSON encoded data, that can either be a list or a
    dict.
    In case of a list, each value in the list will correspond to one
    test case, and the value will be concatenated to the test method
    name.
    In case of a dict, keys will be used as suffixes to the name of the
    test case, and values will be fed as test data.'
