(View In Hierarchy)
Tests for ProxyClient.
| Method | makeRequest | Make a dummy request object for the URL path. | 
| Method | makeProxyClient | Make a ProxyClientobject used for testing. | 
| Method | connectProxy | Connect a proxy client to a StringTransportWithDisconnection. | 
| Method | assertForwardsHeaders | Assert that proxyClientsendsheaderswhen it 
connects. | 
| Method | makeResponseBytes | Undocumented | 
| Method | assertForwardsResponse | Assert that requesthas forwarded a response from the 
server. | 
| Method | test_forward | When connected to the server, ProxyClientshould send the saved request, with modifications of the headers, and then 
forward the result to the parent request. | 
| Method | test_postData | Try to post content in the request, and check that the proxy client forward the body of the request. | 
| Method | test_statusWithMessage | If the response contains a status with a message, it should be forwarded to the parent request with all the information. | 
| Method | test_contentLength | If the response contains a Content-Length header, the inbound 
request object should still only have finishcalled on it 
once. | 
| Method | test_losesConnection | If the response contains a Content-Length header, the outgoing connection is closed when all response body data has been received. | 
| Method | test_headersCleanups | The headers given at initialization should be modified: proxy-connection should be removed if present, and connection should be added. | 
| Method | test_keepaliveNotForwarded | The proxy doesn't really know what to do with keepalive things from the remote server, so we stomp over any keepalive header we get from the client. | 
| Method | test_defaultHeadersOverridden | server.Requestwithin the proxy sets certain response headers by default. When we get 
these headers back from the remote server, the defaults are overridden 
rather than simply appended. | 
| Method | _parseOutHeaders | Parse the headers out of some web content. | 
| Method | _testDataForward | Build a fake proxy connection, and send dataover it, 
checking that it's forwarded to the originating request. | 
Inherited from TestCase:
| Instance Variable | timeout | A real number of seconds. If set, the test will raise an error if it takes 
longer than timeoutseconds. If not set, 
util.DEFAULT_TIMEOUT_DURATION is used. | 
| Method | __init__ | Construct an asynchronous test case for methodName. | 
| Method | assertFailure | Fail if deferreddoes not errback with one ofexpectedFailures. 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,crashandstoponreactor. 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 _deprecateReactordid. | 
| Method | _runCleanups | Run the cleanups added with addCleanupin order. | 
| Method | _runFixturesAndTest | Really run setUp, the test method, andtearDown.  Any of these may returndefer.Deferreds.
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 | Noneor 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 theTestResultsupports skipping). | 
| Instance Variable | todo | None,
a string or a tuple of(errors, reason)whereerrorsis either an exception class or an iterable of 
exception classes, andreasonis a string. SeeTodoormakeTodofor 
more information. | 
| Instance Variable | suppress | Noneor a list of tuples of(args, kwargs)to be passed towarnings.filterwarnings. Use these to suppress warnings raised
in a test. Useful for testing deprecated code. See alsoutil.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 methodNameargument is passed to the constructor,runwill 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 | _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 conditionevaluates to True. | 
| Method | assertTrue | Fail the test if conditionevaluates to False. | 
| Method | assertRaises | Fail the test unless calling the function fwith the givenargsandkwargsraisesexception. 
The failure will report the traceback and call stack of the unexpected 
exception. | 
| Method | assertEqual | Fail the test if firstandsecondare not 
equal. | 
| Method | assertIs | Fail the test if firstis notsecond.  This is
an obect-identity-equality test, not an object equality (i.e.__eq__) test. | 
| Method | assertIsNot | Fail the test if firstissecond.  This is an 
obect-identity-equality test, not an object equality (i.e.__eq__) test. |

| 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 substringdoes not exist withinastring. | 
| Method | assertNotSubstring | Fail if astringcontainssubstring. |

point. | 
| Method | assertRegex | Fail the test if a regexpsearch oftextfails. | 
Parse the headers out of some web content.

| Parameters | path | A URL path, beginning with a slash. | 
| Returns | A DummyRequest. | |
Make a ProxyClient 
object used for testing.
| Parameters | request | The request to use. | 
| method | The HTTP method to use, GET by default. | |

| Returns | A ProxyClient | |
Connect a proxy client to a StringTransportWithDisconnection.
| Parameters | proxyClient | A ProxyClient. | 
| Returns | The StringTransportWithDisconnection. | |
Assert that proxyClient sends headers when it 
connects.
| Parameters | proxyClient | A ProxyClient. | 
| requestLine | The request line we expect to be sent. | |
| headers | A dict of headers we expect to be sent. | |
| Returns | If the assertion is successful, return the request body as bytes. | |
Assert that request has forwarded a response from the 
server.
| Parameters | request | A DummyRequest. | 
| code | The expected HTTP response code. | |
| message | The expected HTTP message. | |
| headers | The expected HTTP headers. | |
| body | The expected response body. | 
Build a fake proxy connection, and send data over it, 
checking that it's forwarded to the originating request.
When connected to the server, ProxyClient 
should send the saved request, with modifications of the headers, and then 
forward the result to the parent request.
Try to post content in the request, and check that the proxy client forward the body of the request.
If the response contains a status with a message, it should be forwarded to the parent request with all the information.
If the response contains a Content-Length header, the inbound 
request object should still only have finish called on it 
once.
If the response contains a Content-Length header, the outgoing connection is closed when all response body data has been received.
The headers given at initialization should be modified: proxy-connection should be removed if present, and connection should be added.
The proxy doesn't really know what to do with keepalive things from the remote server, so we stomp over any keepalive header we get from the client.
server.Request 
within the proxy sets certain response headers by default. When we get 
these headers back from the remote server, the defaults are overridden 
rather than simply appended.
