Inherited from ComparisonTestsMixin:
Method | assertNormalEqualityImplementation | Assert that firstValueOne is equal to
secondValueOne but not equal to valueOne and that
it defines equality cooperatively with other types it doesn't know
about. |
Inherited from TestCase:
Instance Variable | timeout | A real number of seconds. If set, the test will raise an error if it takes
longer than timeout seconds. If not set,
util.DEFAULT_TIMEOUT_DURATION is used. |
Method | __init__ | Construct an asynchronous test case for methodName . |
Method | assertFailure | Fail if deferred does not errback with one of
expectedFailures . Returns the original Deferred with callbacks
added. You will need to return this Deferred from your test case. |

Method | deferSetUp | Undocumented |
Method | deferTestMethod | Undocumented |
Method | deferTearDown | Undocumented |
Method | deferRunCleanups | Run any scheduled cleanups and report errors (if any to the result object. |
Method | addCleanup | Extend the base cleanup feature with support for cleanup functions which return Deferreds. |

Method | _makeReactorMethod | Create a method which wraps the reactor method name . The
new method issues a deprecation warning and calls the original. |
Method | _deprecateReactor | Deprecate iterate , crash and stop
on reactor . That is, each method is wrapped in a function that
issues a deprecation warning, then calls the original. |
Method | _undeprecateReactor | Restore the deprecated reactor methods. Undoes what _deprecateReactor
did. |
Method | _runCleanups | Run the cleanups added with addCleanup
in order. |
Method | _runFixturesAndTest | Really run setUp , the test method, and
tearDown . Any of these may return defer.Deferred s.
After they complete, do some reactor cleanup. |
Method | _wait | Take a Deferred that only ever callbacks. Block until it happens. |
Inherited from SynchronousTestCase (via TestCase):
Instance Variable | failureException | An exception class, defaulting to FailTest . If the test method
raises this exception, it will be reported as a failure, rather than an
exception. All of the assertion methods raise this if the assertion fails. |
Instance Variable | skip | None
or a string explaining why this test is to be skipped. If defined, the test
will not be run. Instead, it will be reported to the result object as
'skipped' (if the TestResult supports skipping). |
Instance Variable | todo | None ,
a string or a tuple of (errors, reason) where
errors is either an exception class or an iterable of
exception classes, and reason is a string. See Todo or makeTodo for
more information. |
Instance Variable | suppress | None
or a list of tuples of (args, kwargs) to be passed to
warnings.filterwarnings . Use these to suppress warnings raised
in a test. Useful for testing deprecated code. See also util.suppress . |

Method | __hash__ | Undocumented |
Method | shortDescription | Undocumented |
Method | getSkip | No summary |
Method | getTodo | No summary |

will treat this method as the thing with the actual test inside. |
Method | run | Run the test case, storing the results in result . |
Method | patch | Monkey patch an object for the duration of the test. |
Method | flushLoggedErrors | Remove stored errors received from the log. |
Method | flushWarnings | Remove stored warnings from the list of captured warnings and return them. |
Method | callDeprecated | Call a function that should have been deprecated at a specific version and in favor of a specific alternative, and assert that it was thusly deprecated. |
Method | mktemp | Create a new path name which can be used for a new file or directory. |
Method | _getSuppress | No summary |
Method | _getSkipReason | Return the reason to use for skipping a test method. |
Method | _installObserver | Undocumented |
Method | _removeObserver | Undocumented |
Inherited from _Assertions (via TestCase, SynchronousTestCase):
Method | fail | Absolutely fail the test. Do not pass go, do not collect $200. |
Method | assertFalse | Fail the test if condition evaluates to True. |
Method | assertTrue | Fail the test if condition evaluates to False. |
Method | assertRaises | Fail the test unless calling the function f with the given
args and kwargs raises exception .
The failure will report the traceback and call stack of the unexpected
exception. |
Method | assertEqual | Fail the test if first and second are not
equal. |
Method | assertIs | Fail the test if first is not second . This is
an obect-identity-equality test, not an object equality (i.e.
__eq__ ) test. |
Method | assertIsNot | Fail the test if first is second . This is an
obect-identity-equality test, not an object equality (i.e.
__eq__ ) test. |

Method | assertIn | Fail the test if containee is not found in
container . |
Method | assertNotIn | Fail the test if containee is found in
container . |
Method | assertNotAlmostEqual | 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. |
Method | assertAlmostEqual | 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. |
Method | assertApproximates | Fail if first - second >
tolerance |
Method | assertSubstring | Fail if substring does not exist within
astring . |
Method | assertNotSubstring | Fail if astring contains substring . |
Method | assertWarns | Fail if the given function doesn't generate the specified warning when called. It calls the function, checks the warning, and forwards the result of the function if everything is fine. |
Method | assertIsInstance | Fail if instance is not an instance of the given class or
of one of the given classes. |
Method | assertNotIsInstance | Fail if instance is an instance of the given class or of
one of the given classes. |

fails. |

reads only the bytes from the current file position to the end of the
record that is being decoded. Trailing bytes are not consumed.

dns._OPTHeader.decode
raises an exception if the supplied RDLEN is too long.
If the OPT bytes contain variable options, dns._OPTHeader.decode
will populate a list dns._OPTHeader.options
with dns._OPTVariableOption
instances.
_OPTHeader.fromRRHeader
accepts an RRHeader
instance
and returns an _OPTHeader
instance whose attribute values have been derived from the

the fixed and extended header values of the OPT record.
Two OPTHeader
instances compare equal if they have the same

Two OPTHeader
instances compare equal if they have the same

instances compare equal if they have the same
version.
