版本信息蟒蛇：3.9 表现：1.2.6 魅力：2.13.5

我有 1 个功能和 1 个场景，3 个步骤会故意失败（它们都有 ZeroDivError）。

特征文件内容如下所示（test.feature）

Feature: Zero division 
  Scenario: people 
   Given Alex divides a number by zero
   Given Tom divides a number by zero 
   Given Mark divides a number by zero

Python中的步骤实现，

from behave import *

@given(u\'Alex divides a number by zero\')
def step_impl(context):
    try:
        a= 5
        quotient= a/0
        print(quotient)
    except:
        raise Exception(\"ZeroDivisionError has happened ALEX\")

@given(u\'Tom divides a number by zero\')
def step_impl(context):
    try:
        t= 10
        quotient= t/0
        print(quotient)
    except:
        raise Exception(\"ZeroDivisionError has happened TOM\")


@given(u\'Mark divides a number by zero\')
def step_impl(context):
    try:
        m= 15
        quotient= m/0
        print(quotient)
    except:
        raise Exception(\"ZeroDivisionError has happened MARK\")

在每一步中，我所做的就是将一个数字除以 0 并为其引发异常。

运行以下命令后在终端中看到的输出

行为特征\\test.feature

输出：TLDR -> 这里没有问题，所有步骤都失败并引发 3 个 ZeroDivisionerrors

自然我得到了想要的输出，所有 3 个步骤都失败了。这里没有问题

现在我运行这个命令来创建魅力报告

表现 -f allure_behave.formatter:AllureFormatter -o ALLURE/features/test.feature

接下来我运行 allure serve 命令，在浏览器中打开 allure 报告。这就是我的问题开始的地方。

我正在链接魅力报告-> https://cosmic-narwhal-c18273.netlify.app/#

这就是为什么在类别下只引发了一个异常，即 ZeroDivisionError 发生在 ALEX 上

为什么我在测试缺陷下看不到其他失败的步骤。

它只显示场景的第一个例外

如何配置 allure 以显示每个失败的步骤及其异常。我错过了什么吗？

请协助

不熟悉这些库或工具，只是在这里说您不应该使用裸露的except。

【解决方案1】：

您的问题中有一些我不明白的地方，那就是您在“行为特征”命令的输出中有一个奇怪的行为。

我已使用 Python 3.9.5 和 Behave 1.2.6 将您的代码复制到一个新的空项目中，当我启动上述命令时，我得到以下输出：

$ behave features/test.feature
Feature: Zero division # features/test.feature:1

  Scenario: people                      # features/test.feature:2
    Given Alex divides a number by zero # steps/steps.py:4
      Traceback (most recent call last):
        File "steps\steps.py", line 8, in step_impl
          quotient = a / 0
      ZeroDivisionError: division by zero

      During handling of the above exception, another exception occurred:

      Traceback (most recent call last):
        File "c:\users\cxb0456\onedrive - telefonica\zz_otros\temporal\pruebaallure\venv\lib\site-packages\behave\model.py", line 1329, in run
          match.run(runner.context)
        File "c:\users\cxb0456\onedrive - telefonica\zz_otros\temporal\pruebaallure\venv\lib\site-packages\behave\matchers.py", line 98, in run
          self.func(context, *args, **kwargs)
        File "steps\steps.py", line 11, in step_impl
          raise Exception("ZeroDivisionError has happened ALEX")
      Exception: ZeroDivisionError has happened ALEX

    Given Tom divides a number by zero  # None
    Given Mark divides a number by zero # None


Failing scenarios:
  features/test.feature:2  people

0 features passed, 1 failed, 0 skipped
0 scenarios passed, 1 failed, 0 skipped
0 steps passed, 1 failed, 2 skipped, 0 undefined
Took 0m0.017s

此输出是我个人习惯的行为，因为如果您在其中一个步骤中出现错误，则不会执行后续步骤并显示为“已跳过”，如果有则继续测试是没有意义的是一个严重的错误（因为它会被零除）。

如果您已修改 Behave 的默认行为以强制其执行失败步骤之后的步骤，则 Behave 与 Allure 的集成可能不如预期。
