目前使用 allure-pytest-adaptor 1.7.8、pytest 3.2.1 和 pytest-xdist 1.20.0

当我使用 xdist 并行运行测试时遇到问题，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 次失败或没有失败，则能够生成诱惑报告

当一次测试运行出现多个失败时，无法生成诱惑报告、堆栈跟踪和错误信息：

我遇到了同样的问题：

  • 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

如果上面的方法对你有用，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）是 xdist 故障与 pytest 和 pytest-allure-adaptor 插件交互的方式。结合起来，它们将失败输出作为 dict 而不是类对象发送，pytest 失败ReprTraceback类使用它来处理失败输出数据。

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。我只是在魅力中更新了现有方法pytest_plugin.py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

我确信有更好的方法来处理这个问题，但看起来这个版本的 allure 项目不再支持更新版本，我觉得这是一个非常棒的升级。我将升级，但以我自己的节奏，因此黑客。

我希望这是有帮助的。
