python - 如何预期 Python 中机器人框架的失败？

Question

我们在工作中使用robot framework做一些自动化测试，我需要添加一些测试。这种格式已经在 repo 中，我不能做任何大的改变。

我正在使用如下所示的关键字文件:

#!/usr/bin/env python3
# -*- coding: utf-8 -*-

from robot.api.deco import keyword

class testkeywords(object):
   """
   """

   def __init__(self):
      pass

   @keyword('I compare ${first_number} with ${second_number}')
   def compare(self, first_number, second_number):
      if (int(first_number) != int(second_number)):
         raise ValueError('Numbers are not the same.')

.robot 文件有两个测试，一个通过，一个失败:

*** Settings ***
Library         testkeywords.py

*** Variables ***
${num_a}       5
${num_b}       6

*** Test Cases ***
Compare same numbers
   I compare ${num_a} with ${num_a}

Compare different numbers
   I compare ${num_a} with ${num_b}

Compare different numbers 测试如预期的那样失败了，但它仍然是 FAIL。我如何设置它以预期失败并因此传递关键字？

Answer 1

我想通了。您可以只修改测试以预期出现如下错误:

Compare different numbers
   Run Keyword And Expect Error  *  I compare ${num_a} with ${num_b}

或者查找特定错误(而不是通配符):

Compare different numbers
       Run Keyword And Expect Error  ValueError: Numbers are not the same.  I compare ${num_a} with ${num_b}

注意命令、错误和关键字之间的双空格。
