【python】unittest中常用的assert语句

下面是unittest模块的常用方法：

assertEqual(a, b)     a == b

assertNotEqual(a, b)     a != b

assertTrue(x)     bool(x) is True

assertFalse(x)     bool(x) is False

assertIs(a, b)     a is b     2.7

assertIsNot(a, b)     a is not b     2.7

assertIsNone(x)     x is None     2.7

assertIsNotNone(x)     x is not None     2.7

assertIn(a, b)     a in b     2.7

assertNotIn(a, b)     a not in b     2.7

assertIsInstance(a, b)     isinstance(a, b)     2.7

assertNotIsInstance(a, b)     not isinstance(a, b)     2.7

assertAlmostEqual(a, b)     round(a-b, 7) == 0

assertNotAlmostEqual(a, b)     round(a-b, 7) != 0

assertGreater(a, b)     a > b     2.7

assertGreaterEqual(a, b)     a >= b     2.7

assertLess(a, b)     a < b     2.7

assertLessEqual(a, b)     a <= b     2.7

assertRegexpMatches(s, re)     regex.search(s)     2.7

assertNotRegexpMatches(s, re)     not regex.search(s)     2.7

assertItemsEqual(a, b)     sorted(a) == sorted(b) and works with unhashable objs     2.7

assertDictContainsSubset(a, b)     all the key/value pairs in a exist in b     2.7

assertMultiLineEqual(a, b)     strings     2.7

assertSequenceEqual(a, b)     sequences     2.7

assertListEqual(a, b)     lists     2.7

assertTupleEqual(a, b)     tuples     2.7

assertSetEqual(a, b)     sets or frozensets     2.7

assertDictEqual(a, b)     dicts     2.7

assertMultiLineEqual(a, b)     strings     2.7

assertSequenceEqual(a, b)     sequences     2.7

assertListEqual(a, b)     lists     2.7

assertTupleEqual(a, b)     tuples     2.7

assertSetEqual(a, b)     sets or frozensets     2.7

assertDictEqual(a, b)     dicts     2.7
