当前使用诱惑pytest适配器1.7.8、pytest 3.2.1和pytest xdist 1.20.0
当我使用xdist并行运行测试时，如果我以串行方式运行测试，则没有这样的问题：
如果只有1个或没有故障，则诱惑报告能够获得生成的
当测试运行中有多个失败时，无法生成诱惑报告，堆栈跟踪和错误消息：

我使用遇到了同样的问题
- Python 2.7.10
- 诱惑pytest适配器1.7.9
- pytest 3.0.0
- pytest xdist 1.20.0
我找到了这个链接，但目前无法升级插件和我的Python版本：
https://github.com/pytest-dev/pytest/issues/2811
如果以上对你有效，那就太好了，但如果你发现自己需要一个补丁来解决你遇到的问题，我有一个可能有用的补丁。
问题(我认为)在于xdist故障与pytest和pytest诱惑适配器插件的交互方式。结合起来，它们将失败输出作为dict而不是类对象发送，pytest failureReprTraceback类使用该对象处理失败输出数据。
这可以通过使用__dict__对象将测试报告属性存储在对象中来解决。事实证明，作者已经部分解决了这个问题。我只是简单地更新了诱惑pytest_plugin.py中的现有方法，以公开所有必要的报告数据，然后用更新的方法替换了预期的报告终结器条件。我有一个来自插件分叉版本的补丁：
https://github.com/weeksghost/allure-python/tree/parallel-test-results
我相信有更好的方法来处理这个问题，但看起来这个版本的诱惑项目不再受支持，取而代之的是更新版本，我觉得这是一个非常棒的升级。我将升级，但在我自己的速度，因此黑客。
我希望这会有所帮助。
