The following example from the README isn't very useful since once the AssertionError is raised in run(), the rest isn't executed.

def test_assert(reraise):

    def run():
        with reraise:
            assert False

    t = Thread(target=run)
    t.start()
    t.join()

    # Return the captured exception:
    assert type(reraise.exception) is AssertionError

Instead I have to perform

import pytest
from threading import Thread

@pytest.mark.xfail(strict=True, raises=ValueError)
def test_assert(reraise):

    def run():
        with reraise:
            raise ValueError

    t = Thread(target=run)
    t.start()
    t.join()

    # This won't be evaluated 
    assert type(reraise.exception) is 5

I feel I'm missing something.

It's great that the exception is raised to the main thread, but you cannot easily check what type it is without using @pytest.mark.xfail(strict=True, raises=ValueError)

It appears that reraise is discarding the traceback in the __exit__. Is this intentional?

Hi

I'm getting this when trying to use the "raise.wrap()" that you mentioned:

AttributeError: module 'pytest_reraise.reraise' has no attribute 'wrap'
