ran testcases by multi-threads, then allure raised /usr/local/lib/python3.9/site-packages/allure_commons/reporter.py:33: KeyError #697Descriptioni ran testcases by multi-threads, then allure raised the error.
version:
python: 3.9.13
allure: 2.14.0
allure-pytest: 2.10.0

@ae86sen 你能不能提供代码例子，以及你到底是如何通过多线程运行测试的？

@pytest.mark.ehpc
def test_hpc():
passIt doesn't have to raised “keyerror” ,but i haven't found the necessary conditions,It seems to be related to the thread isolation of allure? ae86sen commented on Dec 5, 2022 it seems to have something to do with the ”@allure.step“.
there is a new code example:
test_demo.py
import time
import allure
import pytest
@allure.title("hello")
@pytest.mark.d1
@allure.step('123')
def test_hpc():
time.sleep(1)
@allure.title("hello")
@pytest.mark.d2
@allure.step('123')
def test_hpc2():
time.sleep(1)
@allure.title("hello")
@pytest.mark.d3
@allure.step('123')
def test_hpc3():
time.sleep(1)
@allure.title("hello")
@pytest.mark.d4
@allure.step('123')
def test_hpc4():
time.sleep(1)run.py

tp.shutdown()

 ae86sen commented on Dec 5, 2022 i tried to run with v2.8.24 of allure-pytest, it's no problem.
 ae86sen commented on Dec 5, 2022 delatrie commented on Dec 5, 2022 Hi, @ae86sen
Thanks for complete examples and highlights.
The thing is that we have two slightly different scenarios related to multithreading with allure:
- Running tests concurrently in a multithreaded environment (your scenario)
- Running steps concurrently inside a test (see Allure step in thread not show in report. #563)
The changes you are referring to were introduced to deal with (2).
I'll take a look on how to add support for (1). We also have issue with an async concurrency that needs to be addressed as well.
As for now, I advise you (if possible) to utilize xdist, i.e. to use parallel execution in separated processes instead of running tests concurrently in multiple threads. If you don't need to share a common state across your tests that should do the job. ae86sen commented on Dec 6, 2022
thanks！Looking forward to your good news~
