如何使用公共/共享“块”黄瓜特征之间？ [英] How to use common/shared "blocks" between cucumber features?

问题描述

我是新来的黄瓜，但很喜欢它。

I'm new to cucumber, but enjoying it.

我目前正在写一些弗兰克测试，并希望在多个功能中重复使用黄瓜脚本 - 我想这样做一个黄瓜水平如果可能（不在里面的ruby）。

I'm currently writing some Frank tests, and would like to reuse blocks of cucumber script across multiple features - I'd like to do this a the cucumber level if possible (not inside the ruby).

例如，我可能有4个脚本，相同的登录步骤：

For example, I might have 4 scripts that all start by doing the same login steps:

  given my app has started
     then enter "guest" in "user-field"
     and enter "1234" in "password-field"
     and press "login"
  then I will see "welcome"
  then *** here's the work specific to each script ***

有没有办法在多个脚本之间共享前5行？某种类型的包括语法？

Is there any way to share these first 5 lines across multiple scripts? Some kind of "include" syntax?

推荐答案

通常有两种方法：

如果您想要一组步骤

Background:
     given my app has started
     then enter "guest" in "user-field"
     and enter "1234" in "password-field"
     and press "login"
     then I will see "welcome"

Scenario: Some scenario
    then *** here's the work specific to this scenario ***

Scenario: Some other scenario
    then *** here's the work specific to this scenario ***

从步骤定义调用步骤

如果您需要在不同的功能文件中使用块步骤，或者背景部分不适合，因为一些方案不需要它，那么创建一个高级步骤定义来调用其他方法：

Calling steps from step definitions

If you need the 'block' of steps to be used in different feature files, or a Background section is not suitable because some scenarios don't need it, then create a high-level step definition which calls the other ones:

Given /^I have logged in$/ do
    steps %Q {
         given my app has started
         then enter "guest" in "user-field"
         and enter "1234" in "password-field"
         and press "login"
         then I will see "welcome"
    }
end

此外，在这种情况下，我会试图将不是作为单独的步骤来实现您的常见步骤，但创建一个单步定义：（假设Capybara）

---

Also, in this case I'd be tempted not to implement your common steps as separate steps at all, but to create a single step definition: (assuming Capybara)

Given /^I have logged in$/ do
    fill_in 'user-field', :with => 'guest'
    fill_in 'password-field', :with => '1234'
    click_button 'login'
end

更重要的是你的步骤定义，而不是创建一个页面交互的序列，需要在你实现'哦，这部分正在记录我'之前进行精神分析。

This lends a little bit more meaning to your step definitions, rather than creating a sequence of page interactions which need to be mentally parsed before you realise 'oh, this section is logging me in'.
