"""Central interface to stub functions on a given `obj`
`obj` should be a module, a class or an instance of a class; it can be
a Dummy you created with :func:`mock`. ``when`` exposes a fluent interface
where you configure a stub in three steps::
when(<obj>).<method_name>(<args>).thenReturn(<value>)
Compared to simple *patching*, stubbing in mockito requires you to specify
conrete `args` for which the stub will answer with a concrete `<value>`.
All invocations that do not match this specific call signature will be
rejected. They usually throw at call time.
Stubbing in mockito's sense thus means not only to get rid of unwanted
side effects, but effectively to turn function calls into constants.
E.g.::
# Given ``dog`` is an instance of a ``Dog``
when(dog).bark('Grrr').thenReturn('Wuff')
when(dog).bark('Miau').thenRaise(TypeError())
# With this configuration set up:
assert dog.bark('Grrr') == 'Wuff'

Stubbing can effectively be used as monkeypatching; usage shown with
the `with` context managing::
with when(os.path).exists('/foo').thenReturn(True):
...
Most of the time verifying your interactions is not necessary, because
your code under tests implicitly verifies the return value by evaluating
it. See :func:`verify` if you need to, see also :func:`expect` to setup
expected call counts up front.
If your function is pure side effect and does not return something, you
can omit the specific answer. The default then is `None`::
when(manager).do_work()
`when` verifies the method name, the expected argument signature, and the
actual, factual arguments your code under test uses against the original

Mark a class as implementing a Service
Each Service class must have a ``run`` method, which does not take any arguments.
This method is :py:meth:`~.ServiceRunner.adopt`\ ed after the daemon starts, unless
* the Service has been garbage collected, or
* the ServiceUnit has been :py:meth:`~.ServiceUnit.cancel`\ ed.
For each service instance, its :py:class:`~.ServiceUnit` is available at ``service_instance.__service_unit__``. | [

] | Used to convert the source code, making use of known transformers.
"transformers" are modules which must contain a function
transform_source(source)
which returns a tranformed source.
Some transformers (for example, those found in the standard library
module lib2to3) cannot cope with non-standard syntax; as a result, they
may fail during a first attempt. We keep track of all failing
transformers and keep retrying them until either they all succeeded
or a fixed set of them fails twice in a row. | [
