:
Method | set |
Create an in-memory I/O system and set up a TuntapPort against it. |
Method | test_datagram |
If the protocol's datagramReceived method raises an exception, the exception is logged. |
Method | test_datagram |
The exception raised by datagramReceived is logged with a message identifying the offending protocol. |
Method | test_do |
TuntapPort.doRead reads the first part of a datagram of more than TuntapPort.maxPacketSize from the port's file descriptor and passes the truncated data to its protocol's datagramReceived method. |
Method | test_do |
TuntapPort.doRead reads several datagrams, of up to TuntapPort.maxThroughput bytes total, before returning. |
Method | test_do |
TuntapPort.doRead reads a datagram of fewer than TuntapPort.maxPacketSize from the port's file descriptor and passes it to its protocol's datagramReceived method. |
Method | test_eagain |
Once TuntapPort.doRead encounters an EAGAIN errno from a read call, it returns. |
Method | test_eintrblock |
Once TuntapPort.doRead encounters an EINTR errno from a read call, it returns. |
Method | test_ewouldblock |
Once TuntapPort.doRead encounters an EWOULDBLOCK errno from a read call, it returns. |
Method | test_get |
TuntapPort.getHost returns a TunnelAddress including the tunnel's type and name. |
Method | test_interrupted |
If the platform write call is interrupted (causing the Python wrapper to raise IOError with errno set to EINTR), the write is re-tried. |
Method | test_listening |
The string representation of a TuntapPort instance includes the tunnel type and interface and the protocol associated with the port. |
Method | test_log |
TuntapPort.logPrefix returns a string identifying the application protocol and the type of tunnel. |
Method | test_lose |
TuntapPort.loseConnection stops the port and is deprecated. |
Method | test_multiple |
It is safe and a no-op to call TuntapPort.stopListening more than once with no intervening TuntapPort.startListening call. |
Method | test_start |
TuntapPort.startListening calls makeConnection on the protocol the port was initialized with, passing the port as an argument. |
Method | test_start |
TuntapPort.startListening raises CannotListenError if the ioctl call to configure the tunnel device fails. |
Method | test_start |
TuntapPort.startListening raises CannotListenError if opening the tunnel factory character special device fails. |
Method | test_start |
TuntapPort.startListening opens the tunnel factory character special device "/dev/net/tun" and configures it as a tun tunnel. |
Method | test_start |
TuntapPort.startListening sets connected on the port object to True. |
Method | test_start |
TuntapPort.startListening passes the port instance to the reactor's addReader method to begin watching the port's file descriptor for data to read. |
Method | test_stop |
TuntapPort.stopListening calls doStop on the protocol the port was initialized with. |
Method | test_stop |
TuntapPort.stopListening returns a Deferred which fires after the port has been removed from the reactor's reader list by passing it to the reactor's removeReader method. |
Method | test_stop |
After the Deferred returned by TuntapPort.stopListening fires, the connected attribute of the port object is set to False. |
Method | test_stop |
TuntapPort.stopListening returns a Deferred which succeeds immediately if it is called when the port is not listening. |
Method | test_unhandled |
Just like test_unhandledReadError, but for the case where the exception that is not explicitly handled happens to be of type EnvironmentError (OSError or IOError). |
Method | test_unhandled |
If Tuntap.doRead encounters any exception other than one explicitly handled by the code, the exception propagates to the caller. |
Method | test_unhandled |
Any exception raised by the underlying write call, except for EINTR, is propagated to the caller. |
Method | test_unlistening |
The string representation of a TuntapPort instance includes the tunnel type and interface and the protocol associated with the port. |
Method | test |
TuntapPort.write sends a datagram into the tunnel. |
Method | test_write |
TuntapPort.writeSequence sends a datagram into the tunnel by concatenating the byte strings in the list passed to it. |

Method | _datagram |
Deliver some data to a TuntapPort hooked up to an application protocol that raises an exception from its datagramReceived method. |
Method | _stop |
Verify that the stopListening method of an IListeningPort removes that port from the reactor's "readers" set and also that the Deferred returned by that method fires with None . |
Method | _stops |
No summary |
Method | _tunnel |
Mask off any flags except for TunnelType.IFF_TUN and TunnelType.IFF_TAP . |

(via TunnelTestsMixin
):
Method | __eq__ |
Override the comparison defined by the base TestCase which considers instances of the same class with the same _testMethodName to be equal. Since trial puts TestCase instances into a set, that definition of comparison makes it impossible to run the same test method twice... |
Method | __hash__ |
Undocumented |
Method | __init__ |
Undocumented |
Method | add |
Add the given function to a list of functions to be called after the test has run, but before tearDown. |
Method | call |
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 | flush |
Remove stored errors received from the log. |
Method | flush |
Remove stored warnings from the list of captured warnings and return them. |
Method | get |
Retrieve a module attribute which should have been deprecated, and assert that we saw the appropriate deprecation warning. |
Method | get |
Return the skip reason set on this test, if any is set. Checks on the instance first, then the class, then the module, then packages. As soon as it finds something with a skip attribute, returns that in a tuple (... |
Method | get |
Return a Todo object if the test is marked todo. Checks on the instance first, then the class, then the module, then packages. As soon as it finds something with a todo attribute, returns that. Returns ... |
Method | mktemp |
Create a new path name which can be used for a new file or directory. |
Method | patch |
Monkey patch an object for the duration of the test. |
Method | run |
Run the test case, storing the results in result. |
Method | run |
If no methodName argument is passed to the constructor, run will treat this method as the thing with the actual test inside. |
Method | short |
Undocumented |
Instance Variable | failure |
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 | 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 . |
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. |
Method | _get |
Return the reason to use for skipping a test method. |
Method | _get |
Returns any warning suppressions set for this test. Checks on the instance first, then the class, then the module, then packages. As soon as it finds something with a suppress attribute, returns that. ... |
Method | _install |

Method | _remove |
Undocumented |
Method | _run |
Run a single method, either a test method or fixture. |
Method | _run |
