class LineReceiverTests(unittest.SynchronousTestCase): (source)

Test twisted.protocols.basic.LineReceiver, using the LineTester wrapper.

Method	`test_buffer`	Test buffering for different packet size, checking received matches expected data.
Method	`test_clearLineBuffer`	`LineReceiver.clearLineBuffer` removes all buffered data and returns it as a `bytes` and can be called from beneath `dataReceived`.
Method	`test_lineReceivedNotImplemented`	When `LineReceiver.lineReceived` is not overridden in a subclass, calling it raises `NotImplementedError`.
Method	`test_lineReceiverAsProducer`	Test produce/unproduce in receiving.
Method	`test_maximumLineLength`	`LineReceiver` disconnects the transport if it receives a line longer than its `MAX_LENGTH`.
Method	`test_maximumLineLengthPartialDelimiter`	`LineReceiver` doesn't disconnect the transport when it receives a finished line as long as its `MAX_LENGTH`, when the second-to-last packet ended with a pattern that could have been -- and turns out to have been -- the start of a delimiter, and that packet causes the total input to exceed ...
Method	`test_notQuiteMaximumLineLengthUnfinished`	`LineReceiver` doesn't disconnect the transport it if receives a non-finished line whose length, counting the delimiter, is longer than its `MAX_LENGTH` but shorter than its `MAX_LENGTH` + len(delimiter). (When the first part that exceeds the max is the beginning of the delimiter...
Method	`test_pausing`	Test pause inside data receiving. It uses fake clock to see if pausing/resuming work.

Inherited from SynchronousTestCase:

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	`addCleanup`	Add the given function to a list of functions to be called after the test has run, but before `tearDown`.
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	`flushLoggedErrors`	Remove stored errors received from the log.
Method	`flushWarnings`	Remove stored warnings from the list of captured warnings and return them.
Method	`getDeprecatedModuleAttribute`	Retrieve a module attribute which should have been deprecated, and assert that we saw the appropriate deprecation warning.
Method	`getSkip`	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	`getTodo`	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	`runTest`	If no `methodName` argument is passed to the constructor, `run` will treat this method as the thing with the actual test inside.
Method	`shortDescription`	Undocumented
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	`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	`_getSkipReason`	Return the reason to use for skipping a test method.
Method	`_getSuppress`	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	`_installObserver`	Undocumented
Method	`_removeObserver`	Undocumented
Method	`_run`	Run a single method, either a test method or fixture.
Method	`_runCleanups`	Synchronously run any cleanups which have been added.
Method	`_runFixturesAndTest`	Run `setUp`, a test method, test cleanups, and `tearDown`.
Instance Variable	`_cleanups`	Undocumented
Instance Variable	`_observer`	Undocumented
Instance Variable	`_parents`	Undocumented
Instance Variable	`_passed`	Undocumented
Instance Variable	`_testMethodName`	Undocumented
Instance Variable	`_warnings`	Undocumented

Inherited from _Assertions (via SynchronousTestCase):

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	`assertEqual`	Fail the test if `first` and `second` are not equal.
Method	`assertFalse`	Fail the test if `condition` evaluates to True.
Method	`assertIn`	Fail the test if `containee` is not found in `container`.
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	`assertIsInstance`	Fail if `instance` is not an instance of the given class or of one of the given classes.
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	`assertNoResult`	Assert that `deferred` does not have a result at this point.
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	`assertNotEqual`	Fail the test if `first` == `second`.
Method	`assertNotIn`	Fail the test if `containee` is found in `container`.
Method	`assertNotIsInstance`	Fail if `instance` is an instance of the given class or of one of the given classes.
Method	`assertNotSubstring`	Fail if `astring` contains `substring`.
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	`assertSubstring`	Fail if `substring` does not exist within `astring`.
Method	`assertTrue`	Fail the test if `condition` evaluates to False.
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	`fail`	Absolutely fail the test. Do not pass go, do not collect $200.
Method	`failureResultOf`	Return the current failure result of `deferred` or raise `self.failureException`.
Method	`successResultOf`	Return the current success result of `deferred` or raise `self.failureException`.

def test_buffer(self): (source) ¶

Test buffering for different packet size, checking received matches expected data.

def test_clearLineBuffer(self): (source) ¶

LineReceiver.clearLineBuffer removes all buffered data and returns it as a bytes and can be called from beneath dataReceived.

def test_lineReceivedNotImplemented(self): (source) ¶

When LineReceiver.lineReceived is not overridden in a subclass, calling it raises NotImplementedError.

def test_lineReceiverAsProducer(self): (source) ¶

Test produce/unproduce in receiving.

def test_maximumLineLength(self): (source) ¶

LineReceiver disconnects the transport if it receives a line longer than its MAX_LENGTH.

def test_maximumLineLengthPartialDelimiter(self): (source) ¶

LineReceiver doesn't disconnect the transport when it receives a finished line as long as its MAX_LENGTH, when the second-to-last packet ended with a pattern that could have been -- and turns out to have been -- the start of a delimiter, and that packet causes the total input to exceed MAX_LENGTH + len(delimiter).

def test_notQuiteMaximumLineLengthUnfinished(self): (source) ¶

LineReceiver doesn't disconnect the transport it if receives a non-finished line whose length, counting the delimiter, is longer than its MAX_LENGTH but shorter than its MAX_LENGTH + len(delimiter). (When the first part that exceeds the max is the beginning of the delimiter.)

def test_pausing(self): (source) ¶

Test pause inside data receiving. It uses fake clock to see if pausing/resuming work.

def test_rawDataError(self): (source) ¶

LineReceiver.dataReceived forwards errors returned by rawDataReceived.

def test_rawDataReceivedNotImplemented(self): (source) ¶

When LineReceiver.rawDataReceived is not overridden in a subclass, calling it raises NotImplementedError.

def test_rawPausing(self): (source) ¶

Test pause inside raw date receiving.

def test_stackRecursion(self): (source) ¶

Test switching modes many times on the same data.

def test_stopProducing(self): (source) ¶
