- Method resolution order:
- TestDataEdit
- unittest.case.TestCase
- builtins.object
Methods defined here:
- test_raises_error_when_given_directory(self)
- Test that raises error when given a directory.
- test_raises_error_when_given_invalid_file(self)
- Test that raises error when given an invalid file.
Methods inherited from unittest.case.TestCase:
- __call__(self, *args, **kwds)
- Call self as a function.
- __eq__(self, other)
- Return self==value.
- __hash__(self)
- Return hash(self).
- __init__(self, methodName='runTest')
- Create an instance of the class that will use the named test
method when executed. Raises a ValueError if the instance does
not have a method with the specified name.
- __repr__(self)
- Return repr(self).
- __str__(self)
- Return str(self).
- addCleanup(*args, **kwargs)
- Add a function, with arguments, to be called when the test is
completed. Functions added are called on a LIFO basis and are
called after tearDown on test failure or success.
Cleanup items are called even if setUp fails (unlike tearDown).
- addTypeEqualityFunc(self, typeobj, function)
- Add a type specific assertEqual style function to compare a type.
This method is for use by TestCase subclasses that need to register
their own type equality functions to provide nicer error messages.
Args:
typeobj: The data type to call this function on when both values
are of the same type in assertEqual().
function: The callable taking two arguments and an optional
msg= argument that raises self.failureException with a
useful error message when the two arguments are not equal.
- 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
difference 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 significant digit).
If the two objects compare equal then they will automatically
compare almost equal.
- assertAlmostEquals = deprecated_func(*args, **kwargs)
- assertCountEqual(self, first, second, msg=None)
- An unordered sequence comparison asserting that the same elements,
regardless of order. If the same element occurs more than once,
it verifies that the elements occur the same number of times.
self.assertEqual(Counter(list(first)),
Counter(list(second)))
Example:
- [0, 1, 1] and [1, 0, 1] compare equal.
- [0, 0, 1] and [0, 1] compare unequal.
- assertDictContainsSubset(self, subset, dictionary, msg=None)
- Checks whether dictionary is a superset of subset.
- 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 = deprecated_func(*args, **kwargs)
- 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.
- 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.
- assertLogs(self, logger=None, level=None)
- Fail unless a log message of level *level* or higher is emitted
on *logger_name* or its children. If omitted, *level* defaults to
INFO and *logger* defaults to the root logger.
This method must be used as a context manager, and will yield
a recording object with two attributes: `output` and `records`.
At the end of the context manager, the `output` attribute will
be a list of the matching formatted log messages and the
`records` attribute will be a list of the corresponding LogRecord
objects.
Example::
with self.assertLogs('foo', level='INFO') as cm:
logging.getLogger('foo').info('first message')
logging.getLogger('foo.bar').error('second message')
self.assertEqual(cm.output, ['INFO:foo:first message',
'ERROR:foo.bar:second message'])
- 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
difference 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 significant digit).
Objects that are equal automatically fail.
- assertNotAlmostEquals = deprecated_func(*args, **kwargs)
- assertNotEqual(self, first, second, msg=None)
- Fail if the two objects are equal as determined by the '!='
operator.
- assertNotEquals = deprecated_func(*args, **kwargs)
- 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.
- assertNotRegex(self, text, unexpected_regex, msg=None)
- Fail the test if the text matches the regular expression.
- assertNotRegexpMatches = deprecated_func(*args, **kwargs)
- assertRaises(self, expected_exception, *args, **kwargs)
- Fail unless an exception of class expected_exception is raised
by the callable when invoked with specified positional and
keyword arguments. 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 the callable and arguments omitted, will return a
context object used like this::
with self.assertRaises(SomeException):
do_something()
An optional keyword argument 'msg' can be provided when assertRaises
is used as a context object.
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)
- assertRaisesRegex(self, expected_exception, expected_regex, *args, **kwargs)
- Asserts that the message in a raised exception matches a regex.
Args:
expected_exception: Exception class expected to be raised.
expected_regex: Regex (re.Pattern object or string) expected
to be found in error message.
args: Function to be called and extra positional args.
kwargs: Extra kwargs.
msg: Optional message used in case of failure. Can only be used
when assertRaisesRegex is used as a context manager.
- assertRaisesRegexp = deprecated_func(*args, **kwargs)
- assertRegex(self, text, expected_regex, msg=None)
- Fail the test unless the text matches the regular expression.
- assertRegexpMatches = deprecated_func(*args, **kwargs)
- 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.
- assertWarns(self, expected_warning, *args, **kwargs)
- Fail unless a warning of class warnClass is triggered
by the callable when invoked with specified positional and
keyword arguments. If a different type of warning is
triggered, it will not be handled: depending on the other
warning filtering rules in effect, it might be silenced, printed
out, or raised as an exception.
If called with the callable and arguments omitted, will return a
context object used like this::
with self.assertWarns(SomeWarning):
do_something()
An optional keyword argument 'msg' can be provided when assertWarns
is used as a context object.
The context manager keeps a reference to the first matching
warning as the 'warning' attribute; similarly, the 'filename'
and 'lineno' attributes give you information about the line
of Python code from which the warning was triggered.
This allows you to inspect the warning after the assertion::
with self.assertWarns(SomeWarning) as cm:
do_something()
the_warning = cm.warning
self.assertEqual(the_warning.some_attribute, 147)
- assertWarnsRegex(self, expected_warning, expected_regex, *args, **kwargs)
- Asserts that the message in a triggered warning matches a regexp.
Basic functioning is similar to assertWarns() with the addition
that only warnings whose messages also match the regular expression
are considered successful matches.
Args:
expected_warning: Warning class expected to be triggered.
expected_regex: Regex (re.Pattern object or string) expected
to be found in error message.
args: Function to be called and extra positional args.
kwargs: Extra kwargs.
msg: Optional message used in case of failure. Can only be used
when assertWarnsRegex is used as a context manager.
