A custom Should-DSL matcher to use with Dingus

This modules contains a custom matcher so you can use should_dsl with Dingus calls

A small warning: The | operator hack of should_dsl’s doesn’t really go well with the __or__() of a Dingus. I think the | hack is nasty, and I’m not sure I like should_dsl for it. This is where Ruby seems really pretty to me.

You only need to import it

>>> from should_dsl import should, should_not
>>> from dingus import Dingus
>>> import should_dingus

call

Checks calls on a Dingus

>>> stub = Dingus('stub')
>>> def some_function():
...     stub()
...
>>> some_function |should| call(stub)

call can also check that it should be called once:

>>> def some_function():
...     stub()
...     stub()
...
>>> stub.reset()
>>> some_function |should| call(stub)
>>> stub.reset()
>>> some_function |should| call(stub).once
Traceback (most recent call last):
...
ShouldNotSatisfied: <Dingus stub> was called 2 times, expected 1

call can even check the parameters with with_params:

>>> def some_function():
...     stub(True, kwak='tuut', braat='aap')
...
>>> stub.reset()
>>> some_function |should| call(stub).with_params(True, kwak='tuut', braat='aap')
>>> stub.reset()
>>> some_function |should| call(stub).with_params(True, kwak='tuut')
Traceback (most recent call last):
...
ShouldNotSatisfied: <Dingus stub> has not been called with params (True,) {'kwak': 'tuut'}

call with_params can be combined with once:

>>> def some_function():
...     stub(True, kwak='tuut', braat='aap')
...
>>> stub.reset()
>>> some_function |should| call(stub).once.with_params(True, kwak='tuut', braat='aap')
>>> stub.reset()
>>> some_function |should| call(stub).with_params(True, kwak='tuut', braat='aap').once
