# CryptoUtils_test Module

class `virtualsmartcard.tests.CryptoUtils_test.``TestCryptoUtils`(methodName='runTest')

  Bases: `unittest.case.TestCase`

  `_addSkip`(result, reason)
  `_baseAssertEqual`(first, second, msg=None)

    The default assertEqual implementation, not type specific.

  `_classSetupFailed` = False
  `_deprecate`(original_func)
  `_diffThreshold` = 65536
  `_formatMessage`(msg, standardMsg)

    Honour the longMessage attribute when generating failure messages. If longMessage is False this means: * Use only an explicit message if it is provided * Otherwise use the standard message for the assert

    If longMessage is True: * Use the standard message * If an explicit message is provided, plus ‘ : ‘ and the explicit message

  `_getAssertEqualityFunc`(first, second)

    Get a detailed comparison function for the types of the two args.

    Returns: A callable accepting (first, second, msg=None) that will raise a failure exception if first != second with a useful human readable error message for those types.

  `_truncateMessage`(message, diff)
  `addCleanup`(function, *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`(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`(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`(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.

  `assertDictContainsSubset`(expected, actual, msg=None)

    Checks whether actual is a superset of expected.

  `assertDictEqual`(d1, d2, msg=None)
  `assertEqual`(first, second, msg=None)

    Fail if the two objects are unequal as determined by the ‘==’ operator.

  `assertEquals`(first, second, msg=None)

    Fail if the two objects are unequal as determined by the ‘==’ operator.

  `assertFalse`(expr, msg=None)

    Check that the expression is false.

  `assertGreater`(a, b, msg=None)

    Just like self.assertTrue(a > b), but with a nicer default message.

  `assertGreaterEqual`(a, b, msg=None)

    Just like self.assertTrue(a >= b), but with a nicer default message.

  `assertIn`(member, container, msg=None)

    Just like self.assertTrue(a in b), but with a nicer default message.

  `assertIs`(expr1, expr2, msg=None)

    Just like self.assertTrue(a is b), but with a nicer default message.

  `assertIsInstance`(obj, cls, msg=None)

    Same as self.assertTrue(isinstance(obj, cls)), with a nicer default message.

  `assertIsNone`(obj, msg=None)

    Same as self.assertTrue(obj is None), with a nicer default message.

  `assertIsNot`(expr1, expr2, msg=None)

    Just like self.assertTrue(a is not b), but with a nicer default message.

  `assertIsNotNone`(obj, msg=None)

    Included for symmetry with assertIsNone.

  `assertItemsEqual`(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`(a, b, msg=None)

    Just like self.assertTrue(a < b), but with a nicer default message.

  `assertLessEqual`(a, b, msg=None)

    Just like self.assertTrue(a <= b), but with a nicer default message.

  `assertListEqual`(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`(first, second, msg=None)

    Assert that two multi-line strings are equal.

  `assertNotAlmostEqual`(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`(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.

  `assertNotEqual`(first, second, msg=None)

    Fail if the two objects are equal as determined by the ‘!=’ operator.

  `assertNotEquals`(first, second, msg=None)

    Fail if the two objects are equal as determined by the ‘!=’ operator.

  `assertNotIn`(member, container, msg=None)

    Just like self.assertTrue(a not in b), but with a nicer default message.

  `assertNotIsInstance`(obj, cls, msg=None)

    Included for symmetry with assertIsInstance.

  `assertNotRegexpMatches`(text, unexpected_regexp, msg=None)

    Fail the test if the text matches the regular expression.

  `assertRaises`(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`(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`(text, expected_regexp, msg=None)

    Fail the test unless the text matches the regular expression.

  `assertSequenceEqual`(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`(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`(expr, msg=None)

    Check that the expression is true.

  `assertTupleEqual`(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.

  `assert_`(expr, msg=None)

    Check that the expression is true.

  `countTestCases`()
  `debug`()

    Run the test without collecting errors in a TestResult

  `defaultTestResult`()
  `doCleanups`()

    Execute all cleanup functions. Normally called for you after tearDown.

    Fail immediately, with the given message.

  `failIf`(*args, **kwargs)
  `failIfAlmostEqual`(*args, **kwargs)
  `failIfEqual`(*args, **kwargs)
  `failUnless`(*args, **kwargs)
