常用斷言：

1.assertEqual(self, first, second, msg=None)

--判斷兩個參數相等：first == second

2.assertNotEqual(self, first, second, msg=None)

--判斷兩個參數不相等：first ！= second

3.assertIn(self, member, container, msg=None)

--判斷是字符串是否包含：member in container

4.assertNotIn(self, member, container, msg=None)

--判斷是字符串是否不包含：member not in container

5.assertTrue(self, expr, msg=None)

--判斷是否為真：expr is True

6.assertFalse(self, expr, msg=None)

--判斷是否為假：expr is False

7.assertIsNone(self, obj, msg=None)

--判斷是否為None：obj is None

8.assertIsNotNone(self, obj, msg=None)
--判斷是否不為None：obj is not None

2.所有斷言：

assertAlmostEqual(self, first, second, places=None, msg=None, delta=None)
? ? ? Fail if the two objects are unequal as determined by their
? ? ? difference rounded to the given number of decimal places
? ? ? (default 7) and comparing to zero, or by comparing that the
? ? ? between the two objects is more than the given delta.
? ? ??
? ? ? Note that decimal places (from zero) are usually not the same
? ? ? as significant digits (measured from the most signficant digit).
? ? ??
? ? ? If the two objects compare equal then they will automatically
? ? ? compare almost equal.
??
? assertAlmostEquals = assertAlmostEqual(self, first, second, places=None, msg=None, delta=None)
??
? assertDictContainsSubset(self, expected, actual, msg=None)
? ? ? Checks whether actual is a superset of expected.
??
? assertDictEqual(self, d1, d2, msg=None)
??
? assertEqual(self, first, second, msg=None)
? ? ? Fail if the two objects are unequal as determined by the '=='
? ? ? operator.
??
? assertEquals = assertEqual(self, first, second, msg=None)
??
? assertFalse(self, expr, msg=None)
? ? ? Check that the expression is false.
??
? assertGreater(self, a, b, msg=None)
? ? ? Just like self.assertTrue(a > b), but with a nicer default message.
??
? assertGreaterEqual(self, a, b, msg=None)
? ? ? Just like self.assertTrue(a >= b), but with a nicer default message.
??
? assertIn(self, member, container, msg=None)
? ? ? Just like self.assertTrue(a in b), but with a nicer default message.
??
? assertIs(self, expr1, expr2, msg=None)
? ? ? Just like self.assertTrue(a is b), but with a nicer default message.
??
? assertIsInstance(self, obj, cls, msg=None)
? ? ? Same as self.assertTrue(isinstance(obj, cls)), with a nicer
? ? ? default message.
??
? assertIsNone(self, obj, msg=None)
? ? ? Same as self.assertTrue(obj is None), with a nicer default message.
??
? assertIsNot(self, expr1, expr2, msg=None)
? ? ? Just like self.assertTrue(a is not b), but with a nicer default message.
??
? assertIsNotNone(self, obj, msg=None)
? ? ? Included for symmetry with assertIsNone.
??
? assertItemsEqual(self, expected_seq, actual_seq, msg=None)
? ? ? An unordered sequence specific comparison. It asserts that
? ? ? actual_seq and expected_seq have the same element counts.
? ? ? Equivalent to::
? ? ??
? ? ? ? ? self.assertEqual(Counter(iter(actual_seq)),
? ? ? ? ? ? ? ? ? ? ? ? ? ?Counter(iter(expected_seq)))
? ? ??
? ? ? Asserts that each element has the same count in both sequences.
? ? ? Example:
? ? ? ? ? - [0, 1, 1] and [1, 0, 1] compare equal.
? ? ? ? ? - [0, 0, 1] and [0, 1] compare unequal.
??
? assertLess(self, a, b, msg=None)
? ? ? Just like self.assertTrue(a < b), but with a nicer default message.
??
? assertLessEqual(self, a, b, msg=None)
? ? ? Just like self.assertTrue(a <= b), but with a nicer default message.
??
? assertListEqual(self, list1, list2, msg=None)
? ? ? A list-specific equality assertion.
? ? ??
? ? ? Args:
? ? ? ? ? list1: The first list to compare.
? ? ? ? ? list2: The second list to compare.
? ? ? ? ? msg: Optional message to use on failure instead of a list of
? ? ? ? ? ? ? ? ? differences.
??
? assertMultiLineEqual(self, first, second, msg=None)
? ? ? Assert that two multi-line strings are equal.
??
? assertNotAlmostEqual(self, first, second, places=None, msg=None, delta=None)
? ? ? Fail if the two objects are equal as determined by their
? ? ? difference rounded to the given number of decimal places
? ? ? (default 7) and comparing to zero, or by comparing that the
? ? ? between the two objects is less than the given delta.
? ? ??
? ? ? Note that decimal places (from zero) are usually not the same
? ? ? as significant digits (measured from the most signficant digit).
? ? ??
? ? ? Objects that are equal automatically fail.
??
? assertNotAlmostEquals = assertNotAlmostEqual(self, first, second, places=None, msg=None, delta=None)
??
? assertNotEqual(self, first, second, msg=None)
? ? ? Fail if the two objects are equal as determined by the '!='
? ? ? operator.
??
? assertNotEquals = assertNotEqual(self, first, second, msg=None)
??
? assertNotIn(self, member, container, msg=None)
? ? ? Just like self.assertTrue(a not in b), but with a nicer default message.
??
? assertNotIsInstance(self, obj, cls, msg=None)
? ? ? Included for symmetry with assertIsInstance.
??
? assertNotRegexpMatches(self, text, unexpected_regexp, msg=None)
? ? ? Fail the test if the text matches the regular expression.
??
? assertRaises(self, excClass, callableObj=None, *args, **kwargs)
? ? ? Fail unless an exception of class excClass is raised
? ? ? by callableObj when invoked with arguments args and keyword
? ? ? arguments kwargs. If a different type of exception is
? ? ? raised, it will not be caught, and the test case will be
? ? ? deemed to have suffered an error, exactly as for an
? ? ? unexpected exception.
? ? ??
? ? ? If called with callableObj omitted or None, will return a
? ? ? context object used like this::
? ? ??
? ? ? ? ? ?with self.assertRaises(SomeException):
? ? ? ? ? ? ? ?do_something()
? ? ??
? ? ? The context manager keeps a reference to the exception as
? ? ? the 'exception' attribute. This allows you to inspect the
? ? ? exception after the assertion::
? ? ??
? ? ? ? ? with self.assertRaises(SomeException) as cm:
? ? ? ? ? ? ? do_something()
? ? ? ? ? the_exception = cm.exception
? ? ? ? ? self.assertEqual(the_exception.error_code, 3)
??
? assertRaisesRegexp(self, expected_exception, expected_regexp, callable_obj=None, *args, **kwargs)
? ? ? Asserts that the message in a raised exception matches a regexp.
? ? ??
? ? ? Args:
? ? ? ? ? expected_exception: Exception class expected to be raised.
? ? ? ? ? expected_regexp: Regexp (re pattern object or string) expected
? ? ? ? ? ? ? ? ? to be found in error message.
? ? ? ? ? callable_obj: Function to be called.
? ? ? ? ? args: Extra args.
? ? ? ? ? kwargs: Extra kwargs.
??
? assertRegexpMatches(self, text, expected_regexp, msg=None)
? ? ? Fail the test unless the text matches the regular expression.
??
? assertSequenceEqual(self, seq1, seq2, msg=None, seq_type=None)
? ? ? An equality assertion for ordered sequences (like lists and tuples).
? ? ??
? ? ? For the purposes of this function, a valid ordered sequence type is one
? ? ? which can be indexed, has a length, and has an equality operator.
? ? ??
? ? ? Args:
? ? ? ? ? seq1: The first sequence to compare.
? ? ? ? ? seq2: The second sequence to compare.
? ? ? ? ? seq_type: The expected datatype of the sequences, or None if no
? ? ? ? ? ? ? ? ? datatype should be enforced.
? ? ? ? ? msg: Optional message to use on failure instead of a list of
? ? ? ? ? ? ? ? ? differences.
??
? assertSetEqual(self, set1, set2, msg=None)
? ? ? A set-specific equality assertion.
? ? ??
? ? ? Args:
? ? ? ? ? set1: The first set to compare.
? ? ? ? ? set2: The second set to compare.
? ? ? ? ? msg: Optional message to use on failure instead of a list of
? ? ? ? ? ? ? ? ? differences.
? ? ??
? ? ? assertSetEqual uses ducktyping to support different types of sets, and
? ? ? is optimized for sets specifically (parameters must support a
? ? ? difference method).
??
? assertTrue(self, expr, msg=None)
? ? ? Check that the expression is true.
??
? assertTupleEqual(self, tuple1, tuple2, msg=None)
? ? ? A tuple-specific equality assertion.
? ? ??
? ? ? Args:
? ? ? ? ? tuple1: The first tuple to compare.
? ? ? ? ? tuple2: The second tuple to compare.
? ? ? ? ? msg: Optional message to use on failure instead of a list of
? ? ? ? ? ? ? ? ? differences.
