ddt.data(*values)

Method decorator to add to your test methods.

Should be added to methods of instances of unittest.TestCase.

ddt.ddt(cls)

Class decorator for subclasses of unittest.TestCase.

Apply this decorator to the test case class, and then decorate test methods with @data.

For each method decorated with @data, this will effectively create as many methods as data items are passed as parameters to @data.

The names of the test methods follow the pattern test_func_name + "_" + str(data). If data.__name__ exists, it is used instead for the test method name.

For each method decorated with @file_data('test_data.json'), the decorator will try to load the test_data.json file located relative to the python file containing the method that is decorated. It will, for each test_name key create as many methods in the list of values from the data key.

The names of these test methods follow the pattern of test_name + str(data)``

ddt.file_data(value)

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.
