How to use the approvaltests.reporters.generic_diff_reporter.GenericDiffReporter function in approvaltests

def test_non_working_reporter_does_not_report(self):
        self.assertFileDoesNotExist(self.approved_file_path)

        reporter = GenericDiffReporter(('Custom', 'NotReal'))
        success = reporter.report(self.received_file_path, self.approved_file_path)

        self.assertFalse(success)

def test_pycharm_diff_command():
    reporter = GenericDiffReporter(["PyCharm", '/Applications/PyCharm CE.app/Contents/MacOS/pycharm', ["diff"]])
    received_path = "received.txt"
    approved_path = "approved.txt"
    verify(str(reporter.get_command(received_path, approved_path)))

def _create_reporter(config):
        if not config:
            return None
        return GenericDiffReporter(config)

def test_notworking_in_environment(self):
        reporter = GenericDiffReporter(('Custom', 'NotReal'))
        self.assertFalse(reporter.is_working())

def create(diff_tool_path):
        return GenericDiffReporter(['custom', diff_tool_path])
