class documentationtwisted.test.test_twistd
(View In Hierarchy)
Tests for _twistd_unix.UnixApplicationRunner
daemonization.
Method | setUp | Undocumented |
Method | test_success | When double fork succeeded in daemonize , the child process
writes 0 to the status pipe. |
Method | test_successInParent | The parent process initiating the daemonize call reads data
from the status pipe and then exit the process. |
Method | test_successEINTR | If the os.write call to the status pipe raises an
EINTR error, the process child retries to write. |
Method | test_successInParentEINTR | If the os.read call on the status pipe raises an
EINTR error, the parent child retries to read. |
Method | assertErrorWritten | Assert UnixApplicationRunner.postApplication
writes reported to its status pipe if the service raises an
exception whose message is raised . |
Method | test_error | If an error happens during daemonization, the child process writes the exception error to the status pipe. |
Method | test_unicodeError | If an error happens during daemonization, and that error's message is Unicode, the child encodes the message as ascii with backslash Unicode code points. |
Method | assertErrorInParentBehavior | No summary |
Method | test_errorInParent | When the child writes an error message to the status pipe during
daemonization, the parent writes the repr of the message to
stderr and exits with non-zero status code. |
Method | test_nonASCIIErrorInParent | When the child writes a non-ASCII error message to the status pipe
during daemonization, the parent writes the repr of the message to
stderr and exits with a non-zero status code. |
Method | test_errorInParentWithTruncatedUnicode | No summary |
Method | test_errorMessageTruncated | If an error occurs during daemonization and its message is too long, it's truncated by the child. |
Method | test_unicodeErrorMessageTruncated | If an error occurs during daemonization and its message is unicode and too long, it's truncated by the child, even if this splits a unicode escape sequence. |
Method | test_hooksCalled | daemonize indeed calls IReactorDaemonize.beforeDaemonize
and IReactorDaemonize.afterDaemonize
if the reactor implements IReactorDaemonize . |
Method | test_hooksNotCalled | daemonize does NOT call IReactorDaemonize.beforeDaemonize
or IReactorDaemonize.afterDaemonize
if the reactor does NOT implement IReactorDaemonize . |
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 | __call__ | Run the test. Should always do exactly the same thing as run(). |
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 | getSuppress | Undocumented |
Method | getTimeout | No summary |
Method | _run | Run a single method, either a test method or fixture. |
Method | _ebDeferSetUp | Undocumented |
Method | _cbDeferTestMethod | Undocumented |

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 | __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 | 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 | 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. |

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. |
When double fork succeeded in daemonize
, the child process
writes 0 to the status pipe.
The parent process initiating the daemonize
call reads data
from the status pipe and then exit the process.
If the os.write
call to the status pipe raises an
EINTR error, the process child retries to write.
If the os.read
call on the status pipe raises an
EINTR error, the parent child retries to read.
Assert UnixApplicationRunner.postApplication
writes reported
to its status pipe if the service raises an
exception whose message is raised
.
If an error happens during daemonization, the child process writes the exception error to the status pipe.
If an error happens during daemonization, and that error's message is Unicode, the child encodes the message as ascii with backslash Unicode code points.
Make os.read
appear to return readData
, and assert that UnixApplicationRunner.postApplication
writes errorMessage
to standard error and executes the calls
against os
functions specified in mockOSActions
.
When the child writes an error message to the status pipe during
daemonization, the parent writes the repr of the message to
stderr
and exits with non-zero status code.
When the child writes a non-ASCII error message to the status pipe
during daemonization, the parent writes the repr of the message to
stderr
and exits with a non-zero status code.
When the child writes a non-ASCII error message to the status pipe
during daemonization, and that message is too longer, the parent writes the
repr of the truncated message to stderr
and exits with a
non-zero status code.
If an error occurs during daemonization and its message is too long, it's truncated by the child.
If an error occurs during daemonization and its message is unicode and too long, it's truncated by the child, even if this splits a unicode escape sequence.
daemonize
indeed calls IReactorDaemonize.beforeDaemonize
and IReactorDaemonize.afterDaemonize
if the reactor implements IReactorDaemonize
.
daemonize
does NOT call IReactorDaemonize.beforeDaemonize
or IReactorDaemonize.afterDaemonize
if the reactor does NOT implement IReactorDaemonize
.
