php - 场景与场景大纲

Question

背景:

我目前正在为 Symfony2 网页编写行为测试 (Mink/Selenium)。我有很多例子可以引用，实际编写它们应该没问题。步骤定义已经写好了。

但是，在示例中，它们有时会定义一个Scenario:，有时会定义一个Scenario Outline:

问题:

这两种定义测试的方式有什么区别？

Answer 1

来自 the official guide :

Copying and pasting scenarios to use different values can quickly become tedious and repetitive:

Scenario: Eat 5 out of 12
  Given there are 12 cucumbers
  When I eat 5 cucumbers
  Then I should have 7 cucumbers

Scenario: Eat 5 out of 20
  Given there are 20 cucumbers
  When I eat 5 cucumbers
  Then I should have 15 cucumbers

Scenario Outlines allow us to more concisely express these examples through the use of a template with placeholders

Scenario Outline: Eating
  Given there are <start> cucumbers
  When I eat <eat> cucumbers
  Then I should have <left> cucumbers

  Examples:
    | start | eat | left |
    |  12   |  5  |  7   |
    |  20   |  5  |  15  |

The Scenario Outline steps provide a template which is never directly run. A Scenario Outline is run once for each row in the Examples section beneath it (except for the first header row).
