If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem

in environment.py:

def after_all(context):
    global log_destination
    allure.attach.file(log_destination, log_destination.name, allure.attachment_type.TEXT)

It seems like the problem comes from https://github.com/allure-framework/allure-python/blob/master/allure-python-commons/src/reporter.py#L72. All tests where executed and the list contains only elements of type TestResultContainer and not of type ExecutableItem which lead the method to return a None.

The None is propagated cross the framework which lead to a KeyError.

What is the expected behavior?

The log to be attached and no error printed.

What is the motivation / use case for changing the behavior?

We want to attach the logs to the allure reports after all features where called.

Please tell us about your environment:

• Allure version: 2.13.2
• Test framework: [email protected]
• Allure adaptor: [email protected]

Hi, @sebastianpfischer! Thanks for the issue.
Session scoped fixtures aren't implemented in allure-behave. Once they are, attachments from before_all/after_all will go there.
Can't tell you the date estimate for this though, sorry.
