unittest支持各种断言方法。
| 方法 | 检查点 |
|---|---|
| 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 |
| assertIsNot(a, b) | a is not b |
| assertIsNone(x) | x is None |
| assertIsNotNone(x) | x is not None |
| assertIn(a, b) | a in b |
| assertNotIn(a, b) | a not in b |
| assertIsInstance(a, b) | isinstance(a, b) |
| assertNotIsInstance(a, b) | not isinstance(a, b) |
| assertRaises(exc, fun, *args, **kwds) | fun(*args, **kwds) raises exc |
| assertRaisesRegexp(exc, r, fun, *args, **kwds) | fun(*args, **kwds) raises exc and the message matches regex r |
| 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 |
| assertLess(a, b) | a < b |
| assertLessEqual(a, b) | a <= b |
| assertRegexpMatches(s, r) | r.search(s) |
| assertNotRegexpMatches(s, r) | not r.search(s) |
| assertItemsEqual(a, b) | sorted(a) == sorted(b) 也支持unhashable对象 |
| assertDictContainsSubset(a, b) | a里面所有的键值对都在b中存在 |
大家可以自己动手亲自尝试使用这些断言方法。
