twisted.internet.test.test_core.SystemEventTestsBuilder(ReactorBuilder) class documentation

Part of twisted.internet.test.test_core (View In Hierarchy)

Builder defining tests relating to IReactorCore.addSystemEventTrigger and IReactorCore.fireSystemEvent.

Method test_stopWhenNotStarted reactor.stop() raises RuntimeError when called when the reactor has not been started.
Method test_stopWhenAlreadyStopped reactor.stop() raises RuntimeError when called after the reactor has been stopped.
Method test_callWhenRunningOrder Functions are run in the order that they were passed to reactor.callWhenRunning.
Method test_runningForStartupEvents The reactor is not running when "before" "startup" triggers are called and is running when "during" and "after" "startup" triggers are called.
Method test_signalHandlersInstalledDuringStartup Signal handlers are installed in responsed to the "during" "startup".
Method test_stopShutDownEvents reactor.stop() fires all three phases of shutdown event triggers before it makes reactor.run() return.
Method test_shutdownFiresTriggersAsynchronously "before" "shutdown" triggers are not run synchronously from reactor.stop.
Method test_shutdownDisconnectsCleanly A IFileDescriptor.connectionLost implementation which raises an exception does not prevent the remaining IFileDescriptors from having their connectionLost method called.
Method test_multipleRun reactor.run() raises ReactorAlreadyRunning when called when the reactor is already running.
Method test_runWithAsynchronousBeforeStartupTrigger When there is a 'before' 'startup' trigger which returns an unfired Deferred, reactor.run() starts the reactor and does not return until after reactor.stop() is called
Method test_iterate reactor.iterate() does not block.
Method test_crash reactor.crash() stops the reactor and does not fire shutdown triggers.
Method test_runAfterCrash reactor.run() restarts the reactor after it has been stopped by reactor.crash().
Method test_runAfterStop reactor.run() raises ReactorNotRestartable when called when the reactor is being run after getting stopped priorly.

Inherited from ReactorBuilder:

Class Variable skippedReactors A dict mapping FQPN strings of reactors for which the tests defined by this class will be skipped to strings giving the skip message.
Class Variable requiredInterfaces A list of interfaces which the reactor must provide or these tests will be skipped. The default, None, means that no interfaces are required.
Instance Variable reactorFactory A no-argument callable which returns the reactor to use for testing.
Instance Variable originalHandler The SIGCHLD handler which was installed when setUp ran and which will be re-installed when tearDown runs.
Method setUp Clear the SIGCHLD handler, if there is one, to ensure an environment like the one which exists prior to a call to reactor.run.
Method tearDown Restore the original SIGCHLD handler and reap processes as long as there seem to be any remaining.
Method unbuildReactor Clean up any resources which may have been allocated for the given reactor by its creation or by a test which used it.
Method buildReactor Create and return a reactor using self.reactorFactory.
Method getTimeout Determine how long to run the test before considering it failed.
Method runReactor Run the reactor for at most the given amount of time.
Class Method makeTestCaseClasses Create a SynchronousTestCase subclass which mixes in cls for each known reactor and return a dict mapping their names to them.
Instance Variable _reactors A list of FQPN strings giving the reactors for which SynchronousTestCases will be created.
