Test for 'ExceptionError' with py.test

Question

Hello I have an class object dice that eventually deletes itself. Using py.test how can I make py.test return positive to the object deleting itself?

I tried this but it is a syntax error:

assert dice raises(ExceptionError)

Thanks.

Answer 1

You could check globals(). It contains all global variables.

if "dice" in globals():
    do something
else:
    raise(Exception)

Answer 2

With pytest, test for expected errors like this

import pytest

with pytest.raises(ZeroDivisionError):
    1 / 0

that's an example from the docs , chapter Assertions about expected exceptions

In your case it would be something like this

import pytest

with pytest.raises(ExceptionError)
    # Instantiate a dice object
    # Do stuff that makes it delete itself

Here I used the error that you yourself named, I don't know if that is the actual error that is raised.
