如何使用公共/共享“块"；黄瓜功能之间? [英] How to use common/shared "blocks" between cucumber features?

问题描述

我是黄瓜的新手，但很喜欢它.

I'm new to cucumber, but enjoying it.

我目前正在编写一些 Frank 测试，并希望在多个功能中重用黄瓜脚本块 - 如果可能的话，我想在黄瓜级别执行此操作(而不是在 ruby​​ 内部).

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 个脚本都以执行相同的登录步骤开始:

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中共享前 5 行?某种包含"语法?

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

推荐答案

一般有两种方法:

如果您希望在功能文件中的每个场景之前运行一组步骤:

If you want a set of steps to run before each of the scenarios in a feature file:

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 ***

从步骤定义中调用步骤

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，因为某些场景不需要它，那么创建一个调用其他步骤的高级步骤定义:

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，我会不将您的常用步骤作为单独的步骤来实现，而是创建一个单一的步骤定义:(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

这为您的步骤定义赋予了更多意义，而不是创建一系列页面交互，这些交互序列需要在您意识到哦，这部分正在让我登录"之前进行心理解析.

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'.
