【问题描述】：

给定一个特征文件，如下所示：

Feature: Coffee improves mood in the background

  Background:
    Given the user drank coffee

  Scenario Outline: Coffee changes peoples moods
    Then user <USER> should be <MOOD>

    Examples:
      | USER     | MOOD         |
      |  Michael |  happy       |
      |  Elvis   |  electrified |
      |  John    |  sad         |

后台测试步骤“用户喝咖啡”应该运行1次还是3次？

看看下面的人为答案。在输出中，您会看到后台步骤执行了 3 次。

feature.rb:

Feature: Does a background run before each scenario outline?

  Background:
    When I'm a background step

  Scenario Outline: foo
    Then I should print '<count>'

    Examples:
      |count|
      | 10  |
      | 20  |     
      | 30  |

step_def.rb：

When(/^I'm a background step$/) do
  print "BACKGROUND EXECUTED"
end

Then(/^I should print '(\d+)'$/) do |num|
  # empty step
end

输出：

Feature: Does a background run before each scenario outline

BACKGROUND EXECUTED  Background:                  # features/login.feature:3
    When I'm a background step # features/step_definitions/login.rb:1

  Scenario Outline: foo           # features/login.feature:6
    Then I should print '<count>' # features/login.feature:7

    Examples:
      | count |
      | 10    |
BACKGROUND EXECUTED      | 20    |
BACKGROUND EXECUTED      | 30    |

3 scenarios (3 passed)
6 steps (6 passed)
