without a canceller must errback with a defer.CancelledError
and not callback. |

without a canceller, when cancelled must allow a single extra call to
callback, and raise defer.AlreadyCalledError

without a canceller, when cancelled and then callbacked, ignores multiple
cancels thereafter. |

Method | _callback2 | Undocumented |
Method | _errback | Undocumented |
Inherited from SynchronousTestCase:
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 | __init__ | Undocumented |
Method | __eq__ | No summary |
Method | __ne__ | Undocumented |
Method | __hash__ | Undocumented |
Method | shortDescription | Undocumented |
Method | getSkip | No summary |
Method | getTodo | No summary |
Method | runTest | If no methodName argument is passed to the constructor, run
will treat this method as the thing with the actual test inside. |
Method | run | Run the test case, storing the results in result . |
Method | addCleanup | Add the given function to a list of functions to be called after the
test has run, but before tearDown . |
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 | _run | Run a single method, either a test method or fixture. |
Method | _runFixturesAndTest | Run setUp , a test method, test cleanups, and
tearDown . |
Method | _runCleanups | Synchronously run any cleanups which have been added. |
Method | _installObserver | Undocumented |
Method | _removeObserver | Undocumented |
Inherited from _Assertions (via 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 | assertNotEqual | Fail the test if first == second . |
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. |
Method | successResultOf | Return the current success result of deferred or raise
self.failureException . |
Method | failureResultOf | Return the current failure result of deferred or raise
self.failureException . |
Method | assertNoResult | Assert that deferred does not have a result at this
point. |
Method | assertRegex | Fail the test if a regexp search of text
fails. |

A defer.Deferred
without a canceller, when cancelled and then errbacked, ignores multiple

Calling cancel multiple times on a deferred with no canceller results in
a defer.CancelledError
.
Subsequent calls to cancel do not cause an error.
Verify that calling cancel multiple times on a deferred with a canceller
that does not errback results in a defer.CancelledError
and that subsequent calls to cancel do not cause an error and that after
all that, the canceller was only called once.
Verify that a defer.Deferred
calls its specified canceller when it is cancelled, and that further
call/errbacks raise defer.AlreadyCalledError
.

after
it has been errbacked does not result in a defer.CancelledError
.
Verify that a Deferred, a, which is waiting on another Deferred, b,
returned from one of its callbacks, will propagate defer.CancelledError
when a is cancelled.
