twisted.web.test.test_newclient.HTTPClientParserTests

Tests for HTTPClientParser which is responsible for parsing HTTP response messages.

Method	test_parseVersion	`HTTPClientParser.parseVersion` parses a status line into its three components.
Method	test_parseBadVersion	`HTTPClientParser.parseVersion` raises `ValueError` when passed an unparsable version.
Method	test_responseStatusParsing	`HTTPClientParser.statusReceived` parses the version, code, and phrase from the status line and stores them on the response object.
Method	test_responseStatusWithoutPhrase	`HTTPClientParser.statusReceived` can parse a status line without a phrase (though such lines are a violation of RFC 7230, section 3.1.2; nevertheless some broken servers omit the phrase).
Method	test_badResponseStatus	`HTTPClientParser.statusReceived` raises `ParseError` if it is called with a status line which cannot be parsed.
Method	test_headResponse	If the response is to a HEAD request, no body is expected, the body callback is not invoked, and the Content-Length header is passed to the header callback.
Method	test_noContentResponse	If the response code is NO CONTENT (204), no body is expected and the body callback is not invoked.
Method	test_notModifiedResponse	If the response code is NOT MODIFIED (304), no body is expected and the body callback is not invoked.
Method	test_responseHeaders	The response headers are added to the response object's `headers` `Headers` instance.
Method	test_responseHeadersMultiline	The multi-line response headers are folded and added to the response object's `headers` `Headers` instance.
Method	test_connectionHeaders	The connection control headers are added to the parser's `connHeaders` `Headers` instance.
Method	test_headResponseContentLengthEntityHeader	If a HEAD request is made, the Content-Length header in the response is added to the response headers, not the connection control headers.
Method	test_contentLength	If a response includes a body with a length given by the Content-Length header, the bytes which make up the body are passed to the `_bodyDataReceived` callback on the `HTTPParser`.
Method	test_zeroContentLength	If a response includes a Content-Length header indicating zero bytes in the response, `Response.length` is set accordingly and no data is delivered to `Response._bodyDataReceived`.
Method	test_multipleContentLengthHeaders	If a response includes multiple Content-Length headers, `HTTPClientParser.dataReceived` raises `ValueError` to indicate that the response is invalid and the transport is now unusable.
Method	test_extraBytesPassedBack	If extra bytes are received past the end of a response, they are passed to the finish callback.
Method	test_extraBytesPassedBackHEAD	If extra bytes are received past the end of the headers of a response to a HEAD request, they are passed to the finish callback.
Method	test_chunkedResponseBody	If the response headers indicate the response body is encoded with the chunked transfer encoding, the body is decoded according to that transfer encoding before being passed to `Response._bodyDataReceived`.
Method	test_unknownContentLength	If a response does not include a Transfer-Encoding or a Content-Length, the end of response body is indicated by the connection being closed.
Method	test_contentLengthAndTransferEncoding	According to RFC 2616, section 4.4, point 3, if Content-Length and Transfer-Encoding: chunked are present, Content-Length MUST be ignored
Method	test_connectionLostBeforeBody	If `HTTPClientParser.connectionLost` is called before the headers are finished, the `_responseDeferred` is fired with the `Failure` passed to `connectionLost`.
Method	test_connectionLostWithError	If one of the `Response` methods called by `HTTPClientParser.connectionLost` raises an exception, the exception is logged and not re-raised.
Method	test_noResponseAtAll	If no response at all was received and the connection is lost, the resulting error is `ResponseNeverReceived`.
Method	test_someResponseButNotAll	If a partial response was received and the connection is lost, the resulting error is `ResponseFailed`, but not `ResponseNeverReceived`.
Method	test_1XXResponseIsSwallowed	If a response in the 1XX range is received it just gets swallowed and the parser resets itself.
Method	test_1XXFollowedByFinalResponseOnlyEmitsFinal	When a 1XX response is swallowed, the final response that follows it is the only one that gets sent to the application.
Method	test_multiple1XXResponsesAreIgnored	It is acceptable for multiple 1XX responses to come through, all of which get ignored.
Method	test_ignored1XXResponseCausesLog	When a 1XX response is ignored, Twisted emits a log.
Method	_noBodyTest	Assert that `HTTPClientParser` parses the given `response` to `request`, resulting in a response with no body and no extra bytes and leaving the transport in the producing state.

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	_ebDeferTestMethod	Undocumented
Method	_ebDeferTearDown	Undocumented
Method	_cbDeferRunCleanups	Undocumented
Method	_cleanUp	Undocumented
Method	_classCleanUp	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.
Method	successResultOf	Return the current success result of `deferred` or raise `self.failureException`.
