我正在使用 pytest-6.2.4 通过插件 allure-pytest-bdd-2.8.36、bdd-4.0.2 进行测试自动化。Python 版本是 3.6.9。

使用标志 --alluredir=reports 运行 pytest 时发生 KeyError。测试包含带有示例的功能：

| empty_answer1    | <- variable name
| ---------------- |
| {"playlists":[]} | <- variable value
| {"playlists":[]} | <- variable value

据我所知，控制台输出显示错误发生在格式化过程中：

    @pytest.mark.usefixtures(*function_args)
    def scenario_wrapper(request):

示例类型已通过 example_converters 在 python 脚本中显式声明，如下所示：

scenarios('../features/requestroutePL.feature', example_converters=dict(locality=str,
                                                                        route=str,
                                                                        trip=str,
                                                                        mmetype=str,
                                                                        statusPL=str,
                                                                        urlwithroute=str,
                                                                        urlwithroute2=str,
                                                                        empty_answer1=str,
                                                                        urlwithroute3=str,
                                                                        empty_answer2=str))

我试图用 ''、'%' 符号转义大括号，并使大括号加倍。那一切都是徒劳的。请帮我解决这个问题。我已经没有想法了。

唯一使测试通过的事情是从示例中完全删除大括号。但这个可疑的步骤似乎不是答案。最重要的是，这种行为是不一致的，bcs 在另一个测试中的相同构造没有引发任何错误。

非常感谢任何帮助。
