【十】behave之用背景use background实例九

目标：使用后台概念在每个场景之前执行许多步骤

1.编写Feature Test 功能测试，这里是沿用之前的实例三

## Created by bxf at 2019/11/12
#Feature: Using Background --购买化妆品(Natural Language Part2,tutorial09)

Feature: 用背景
  Background: 肤质设置
    Given 不同女生不同肤质

  Scenario: 油皮
    Given 化妆品我有lanKou
    When 女生是girlB
    Then 脸的感觉应该是自然

  Scenario: 干皮
    Given 化妆品我有IPSA
    When 女生是girlA
    Then 脸的感觉应该是服帖

2.编写自动化测试

@then('脸的感觉应该是{feel}')

    assert_that(feel, equal_to(context.cosmetics.Fit()))

3.运行自动化测试
