New issue 682: Check if several functions are called
https://bitbucket.org/hpk42/pytest/issue/682/check-if-several-functions-are-called
Unknown Name:
I wanted to check if several functions were called during the test and I
implemented the class bellow. I don't know if you're interested in it.
Unfortunately, the code with the tests using this class turned out to be
useless. So I don't even know if it is useful.
```python
class StateTesting:
"""A class to test if some functions are called."""
def __init__(self, final_states):
"""
:param final_states: A list of final states.
:type final_states: list
"""
self.len = len(final_states)
self.final_states = final_states
self.states = [False] * self.len
@staticmethod
def test(final_states):
"""Create a decorator to test the function.
:param final_states: A list of final states.
:type final_states: list
:return: A decorator.
:rtype: func
"""
def decorator(func):
def wrapper(*args, **kwargs):
obj = StateTesting(final_states)
func(obj, *args, **kwargs)
# Test if the functions have been called
for i in range(obj.len):
assert obj.states[i] == obj.final_states[i]
return wrapper
return decorator
def decorate(self, callback, index):
"""Return a function setting `self.states[index]` to `True` and calling
`callback`.
:param callback: A callback to be called.
:param index: The index to be toggled.
:type callback: callable
:type index: int
:rtype: func
"""
def func(*args, **kwargs):
self.states[index] = True
callback(*args, **kwargs)
return func
```
To be used like that:
```python
def callback1(data):
pass
def callback2(data):
pass
def callback3(data):
pass
@StateTesting.test([True, False, True])
def test_sth(state_obj):
process(arg1, arg2, callback=state_obj.decorate(callback1, 0))
process_not_to_be_supposed_to_call_its_callback(arg3,
callback=state_obj.decorate(callback2, 1))
other_process(arg, callback=state_obj.decorate(callback1, 2))
```
Thanks.
