Tests for proxyForInterface
.
Method | test_original | Proxy objects should have an original attribute which
refers to the original object passed to the constructor. |
Method | test_proxyMethod | The class created from proxyForInterface
passes methods on an interface to the object which is passed to its
constructor. |
Method | test_decoratedProxyMethod | Methods of the class created from proxyForInterface
can be used with the decorator-helper functools.wraps . |
Method | test_proxyAttribute | Proxy objects should proxy declared attributes, but not other attributes. |
Method | test_proxySetAttribute | The attributes that proxy objects proxy should be assignable and affect the original object. |
Method | test_proxyDeleteAttribute | The attributes that proxy objects proxy should be deletable and affect the original object. |
Method | test_multipleMethods | [Regression test] The proxy should send its method calls to the correct method, not the incorrect one. |
Method | test_subclassing | It is possible to subclass the result of proxyForInterface . |
Method | test_proxyName | The name of a proxy class indicates which interface it proxies. |
Method | test_implements | The resulting proxy implements the interface that it proxies. |
Method | test_proxyDescriptorGet | No summary |
Method | test_proxyInheritance | Subclasses of the class returned from proxyForInterface
should be able to upcall methods by reference to their superclass, as any
normal Python class can. |
Method | test_interfaceInheritance | Proxies of subinterfaces generated with proxyForInterface should allow access to attributes of both the child and the base interfaces. |
Method | test_attributeCustomization | No summary |
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. |
Proxy objects should have an original
attribute which
refers to the original object passed to the constructor.
The class created from proxyForInterface
passes methods on an interface to the object which is passed to its
constructor.
Methods of the class created from proxyForInterface
can be used with the decorator-helper functools.wraps
.
Proxy objects should proxy declared attributes, but not other attributes.
The attributes that proxy objects proxy should be assignable and affect the original object.
The attributes that proxy objects proxy should be deletable and affect the original object.
[Regression test] The proxy should send its method calls to the correct method, not the incorrect one.
_ProxyDescriptor's __get__ method should return the appropriate attribute of its argument's 'original' attribute if it is invoked with an object. If it is invoked with None, it should return a false class-method emulator instead.
For some reason, Python's documentation recommends to define descriptors' __get__ methods with the 'type' parameter as optional, despite the fact that Python itself never actually calls the descriptor that way. This is probably do to support 'foo.__get__(bar)' as an idiom. Let's make sure that the behavior is correct. Since we don't actually use the 'type' argument at all, this test calls it the idiomatic way to ensure that signature works; test_proxyInheritance verifies the how-Python-actually-calls-it signature.
Subclasses of the class returned from proxyForInterface
should be able to upcall methods by reference to their superclass, as any
normal Python class can.
Proxies of subinterfaces generated with proxyForInterface should allow access to attributes of both the child and the base interfaces.
The original attribute name can be customized via the
originalAttribute
argument of proxyForInterface
:
the attribute should change, but the methods of the original object should
still be callable, and the attributes still accessible.
