Tests for twisted.protocols.basic.NetstringReceiver.

Method setUp Undocumented
Method test_buffer Strings can be received in chunks of different lengths.
Method test_receiveEmptyNetstring Empty netstrings (with length '0') can be received.
Method test_receiveOneCharacter One-character netstrings can be received.
Method test_receiveTwoCharacters Two-character netstrings can be received.
Method test_receiveNestedNetstring Netstrings with embedded netstrings. This test makes sure that the parser does not become confused about the ',' and ':' characters appearing inside the data portion of the netstring.
Method test_moreDataThanSpecified Netstrings containing more data than expected are refused.
Method test_moreDataThanSpecifiedBorderCase Netstrings that should be empty according to their length specification are refused if they contain data.
Method test_missingNumber Netstrings without leading digits that specify the length are refused.
Method test_missingColon Netstrings without a colon between length specification and data are refused.
Method test_missingNumberAndColon Netstrings that have no leading digits nor a colon are refused.
Method test_onlyData Netstrings consisting only of data are refused.
Method test_receiveNetstringPortions_1 Netstrings can be received in two portions.
Method test_receiveNetstringPortions_2 Netstrings can be received in more than two portions, even if the length specification is split across two portions.
Method test_receiveNetstringPortions_3 Netstrings can be received one character at a time.
Method test_receiveTwoNetstrings A stream of two netstrings can be received in two portions, where the first portion contains the complete first netstring and the length specification of the second netstring.
Method test_maxReceiveLimit Netstrings with a length specification exceeding the specified MAX_LENGTH are refused.
Method test_consumeLength _consumeLength returns the expected length of the netstring, including the trailing comma.
Method test_consumeLengthBorderCase1 _consumeLength works as expected if the length specification contains the value of MAX_LENGTH (border case).
Method test_consumeLengthBorderCase2 _consumeLength raises a basic.NetstringParseError if the length specification exceeds the value of MAX_LENGTH by 1 (border case).
Method test_consumeLengthBorderCase3 _consumeLength raises a basic.NetstringParseError if the length specification exceeds the value of MAX_LENGTH by more than 1.
Method test_stringReceivedNotImplemented When NetstringReceiver.stringReceived is not overridden in a subclass, calling it raises NotImplementedError.

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.

Inherited from LPTestCaseMixin:

Method getProtocol Return a new instance of self.protocol connected to a new instance of proto_helpers.StringTransport.
Method test_illegal Assert that illegal strings cause the transport to be closed.
