什么是黄瓜数据表的正则表达式

Question

我在找到黄瓜数据表中数字的正确RE时遇到问题。

我的情况是这样的：

local_dhcp.feature

   Feature:
     Scenario Outline:
     Given I have a valid username plus MAC address
     When the user <user> with <mac> logs on to Sonar
     Then the expected result should be <Expected_Result>

Examples:
    | user | mac         | Expected_Result|
    | mattwwww | 200000000001 | OK |
    | matt | 200000000001 | OK |

local_dhcp.rb

Given /^I have a valid username plus MAC address$/ do 
  @rad = RadiusClient.new
end

When /^the user "(.*?)" with "(\d+)" logs on to Sonar$/ do |username, mac|
  puts "user: #{username} mac: #{mac}"
  @rad.send(username, mac)
end

Then /^the expected result should be "(.*?)"$/ do |result|
   # table is a Cucumber::Ast::Table
  pending # express the regexp above with the code you wish you had
end

黄瓜特征\ test.feature

我的问题是：

1. 看截图，它说2过去了，但是，我怎么会在底部看到这个： 您可以使用以下代码段实现未定义步骤的步骤定义： When /^the user mattwww with (\d+) logs on to Sonar$/ do |arg1| 对我来说，看起来像mac地址200000000001没有传入。或者，我错了吗？

2. @rad.send（username，mac）这句话没有运行。我试过这个“用户：＃{username} mac：＃{mac}”，没有显示值。怎么会？

Answer 1

如果查看步骤定义中的正则表达式，参数周围会有双引号。这就是他们与功能步骤不匹配的原因。要解决这个问题，您需要做的就是在功能中添加引号：

Feature:
  Scenario Outline:
  Given I have a valid username plus MAC address
  When the user "<user>" with "<mac>" logs on to Sonar
  Then the expected result should be "<Expected_Result>"

Examples:
  | user | mac         | Expected_Result|
  | mattwwww | 200000000001 | OK |
  | matt | 200000000001 | OK |

或从正则表达式中删除它们：

/^I have a valid username plus MAC address$/
/^the user (.*?) with (\d+) logs on to Sonar$/
/^the expected result should be (.*?)$/
