Using Assert Methods in Unittest: Validating Test Results
The assert methods are part of the unittest.TestCase class and are used to check conditions in your tests.
Simply put, each test method in the Test class concludes with a statement such as self.assert.
Commonly Used assert Methods
| Method | Check | Example |
|---|---|---|
| assertEqual(a, b) | a == b | assertEqual(sum([1, 2, 3]), 6) |
| assertNotEqual(a, b) | a != b | assertNotEqual(1, 2) |
| assertTrue(x) | bool(x) is True | assertTrue(isinstance(123, int)) |
| assertFalse(x) | bool(x) is False | assertFalse(isinstance("hello", int)) |
| assertIs(a, b) | a is b | a = 1, b = a |
| assertIsNone(x) | x is None | book.price = None |
| assertIn(a, b) | a in b | assertIn(2, [1, 2, 3]) |
| assertIsInstance(a, b) | isinstance(a, b) | assertIsInstance(123, int) |
Also, assertRaises(Error, func, *args, **kwargs) is used to test that an error is raised. For example:
python
This checks that converting "xyz" to integer raises ValueError.
