Python\u2019s unittest module doesn\u2019t seem to have such a\nfeature.\n\nPHPUnit\u2019s version\n-----------------\n\nThe data provider returns a two-dimensional array of test arguments. For\nexample::\n\n    class CssParserTest extends PHPUnit_Framework_TestCase {\n        function setUp() {\n            $this->parser = new CssParser();\n        }\n    \n        /**\n        * @dataProvider cssColors\n        */\n        function testParseColor($color, $notation) {\n            $this->assertEquals($color, $this->parser->parseColor($notation));\n        }\n    \n    \n        function cssColors() {\n            return array(\n                array(array(0, 0, 0), '#000'),\n                array(array(0, 0, 0), '#000000'),\n                array(array(0, 0, 0), 'rgb(0, 0, 0)')\n                array(array(0, 0, 0), 'black')\n            );\n        }\n    }\n\nRunning this test would call the testParseColor() test 4 times, with each of\nthe arrays returned by cssColors() as the arguments.\n\nPython: providing test data using a decorator\n---------------------------------------------\n\nWhile writing tests for some Python code, I discovered that Python\u2019s unittest\ndoesn\u2019t seem to have such a feature. So I implemented my own, using a\ndecorator::\n\n    def data_provider(fn_data_provider):\n        \"\"\"Data provider decorator, allows another callable to provide the data for the test\"\"\"\n        def test_decorator(fn):\n            def repl(self, *args):\n                for i in fn_data_provider():\n                    try:\n                        fn(self, *i)\n                    except AssertionError:\n                        print \"Assertion error caught with data set \", i\n                        raise\n            return repl\n        return test_decorator\n\nExample usage::\n\n    class CssParserTest:\n        def setUp(self):\n            self.parser = CssColor()\n    \n        colors = lambda: (\n            ( (0, 0, 0), '#000' ),\n            ( (0, 0, 0), '#000000' ),\n            ( (0, 0, 0), 'rgb(0, 0, 0)' ),\n            ( (0, 0, 0), 'black' )\n        )\n    \n        @data_provider(colors):\n        def test_parse_color(self, color, notation):\n            self.assertEquals(color, self.parser.parse_color(notation))\n\nSuggestions of alternatives are greatly appreciated, by the way.",
