twisted.test.test_memcache.CommandMixin

Known subclasses: twisted.test.test_memcache.CommandFailureTests, twisted.test.test_memcache.MemCacheTests

Setup and tests for basic invocation of MemCacheProtocol commands.

Method	test_get	`MemCacheProtocol.get` returns a `Deferred` which is called back with the value and the flag associated with the given key if the server returns a successful result.
Method	test_emptyGet	Test getting a non-available key: it succeeds but return `None` as value and `0` as flag.
Method	test_getMultiple	`MemCacheProtocol.getMultiple` returns a `Deferred` which is called back with a dictionary of flag, value for each given key.
Method	test_getMultipleWithEmpty	When `MemCacheProtocol.getMultiple` is called with non-available keys, the corresponding tuples are (0, None).
Method	test_set	`MemCacheProtocol.set` returns a `Deferred` which is called back with `True` when the operation succeeds.
Method	test_add	`MemCacheProtocol.add` returns a `Deferred` which is called back with `True` when the operation succeeds.
Method	test_replace	`MemCacheProtocol.replace` returns a `Deferred` which is called back with `True` when the operation succeeds.
Method	test_errorAdd	Test an erroneous add: if a `MemCacheProtocol.add` is called but the key already exists on the server, it returns a NOT STORED answer, which calls back the resulting `Deferred` with `False`.
Method	test_errorReplace	Test an erroneous replace: if a `MemCacheProtocol.replace` is called but the key doesn't exist on the server, it returns a NOT STORED answer, which calls back the resulting `Deferred` with `False`.
Method	test_delete	`MemCacheProtocol.delete` returns a `Deferred` which is called back with `True` when the server notifies a success.
Method	test_errorDelete	Test an error during a delete: if key doesn't exist on the server, it returns a NOT FOUND answer which calls back the resulting `Deferred` with `False`.
Method	test_increment	Test incrementing a variable: `MemCacheProtocol.increment` returns a `Deferred` which is called back with the incremented value of the given key.
Method	test_decrement	Test decrementing a variable: `MemCacheProtocol.decrement` returns a `Deferred` which is called back with the decremented value of the given key.
Method	test_incrementVal	`MemCacheProtocol.increment` takes an optional argument `value` which replaces the default value of 1 when specified.
Method	test_decrementVal	`MemCacheProtocol.decrement` takes an optional argument `value` which replaces the default value of 1 when specified.
Method	test_stats	Test retrieving server statistics via the `MemCacheProtocol.stats` command: it parses the data sent by the server and calls back the resulting `Deferred` with a dictionary of the received statistics.
Method	test_statsWithArgument	No summary
Method	test_version	Test version retrieval via the `MemCacheProtocol.version` command: it returns a `Deferred` which is called back with the version sent by the server.
Method	test_flushAll	`MemCacheProtocol.flushAll` returns a `Deferred` which is called back with `True` if the server acknowledges success.
Method	_test	Helper test method to test the resulting `Deferred` of a `MemCacheProtocol` command.

def _test(self, d, send, recv, result):

overridden in twisted.test.test_memcache.CommandFailureTests, twisted.test.test_memcache.MemCacheTests

Helper test method to test the resulting Deferred of a MemCacheProtocol command.

def test_get(self):

MemCacheProtocol.get returns a Deferred which is called back with the value and the flag associated with the given key if the server returns a successful result.

def test_emptyGet(self):

Test getting a non-available key: it succeeds but return None as value and 0 as flag.

def test_getMultiple(self):

MemCacheProtocol.getMultiple returns a Deferred which is called back with a dictionary of flag, value for each given key.

def test_getMultipleWithEmpty(self):

When MemCacheProtocol.getMultiple is called with non-available keys, the corresponding tuples are (0, None).

def test_set(self):

MemCacheProtocol.set returns a Deferred which is called back with True when the operation succeeds.

def test_add(self):

MemCacheProtocol.add returns a Deferred which is called back with True when the operation succeeds.

def test_replace(self):

MemCacheProtocol.replace returns a Deferred which is called back with True when the operation succeeds.

def test_errorAdd(self):

Test an erroneous add: if a MemCacheProtocol.add is called but the key already exists on the server, it returns a NOT STORED answer, which calls back the resulting Deferred with False.

def test_errorReplace(self):

Test an erroneous replace: if a MemCacheProtocol.replace is called but the key doesn't exist on the server, it returns a NOT STORED answer, which calls back the resulting Deferred with False.

def test_delete(self):

MemCacheProtocol.delete returns a Deferred which is called back with True when the server notifies a success.

def test_errorDelete(self):

Test an error during a delete: if key doesn't exist on the server, it returns a NOT FOUND answer which calls back the resulting Deferred with False.

def test_increment(self):

Test incrementing a variable: MemCacheProtocol.increment returns a Deferred which is called back with the incremented value of the given key.

def test_decrement(self):

Test decrementing a variable: MemCacheProtocol.decrement returns a Deferred which is called back with the decremented value of the given key.

def test_incrementVal(self):

MemCacheProtocol.increment takes an optional argument value which replaces the default value of 1 when specified.

def test_decrementVal(self):

MemCacheProtocol.decrement takes an optional argument value which replaces the default value of 1 when specified.

def test_stats(self):

Test retrieving server statistics via the MemCacheProtocol.stats command: it parses the data sent by the server and calls back the resulting Deferred with a dictionary of the received statistics.

def test_statsWithArgument(self):

MemCacheProtocol.stats takes an optional bytes argument which, if specified, is sent along with the STAT command. The STAT responses from the server are parsed as key/value pairs and returned as a dict (as in the case where the argument is not specified).

def test_version(self):

Test version retrieval via the MemCacheProtocol.version command: it returns a Deferred which is called back with the version sent by the server.

def test_flushAll(self):

MemCacheProtocol.flushAll returns a Deferred which is called back with True if the server acknowledges success.
