视频教程传送门 -> [https://ke.qq.com/course/417461?taid=3602902036143797][https_ke.qq.com_course_417461_taid_3602902036143797]

Selenium2Library基于Selenium针对robot framework开发的一个库，用于Web自动化测试。

1. 首先要安装Selenium2Library ->

pip install robotframework-selenium2library

注：安装其它库可以去[https://robotframework.org/][https_robotframework.org] 找到对应库的github下载地址，参照readme说明完成安装。

使用 pip show robotframework-selenium2library 查看存放位置

C:\rf>pip show robotframework-selenium2library
    Name: robotframework-selenium2library
    Version: 3.0.0
    Summary: Web testing library for Robot Framework
    Home-page: https://github.com/robotframework/Selenium2Library
    Author: Tatu Aalto

    Location: c:\users\lenovo\appdata\local\programs\python\python37\lib\site-packages
    Requires: robotframework-seleniumlibrary
    Required-by:
    
    C:\rf>

在以上位置可以找到 Selenium2Library，复制

2. 打开RIDE，创建一个新的测试套件，例如Sele\_test

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3d5X2hoeHg_size_16_color_FFFFFF_t_70][]

Name中输入刚才复制的 “Selenium2Library”

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3d5X2hoeHg_size_16_color_FFFFFF_t_70 1][]

库名显示为黑色表示添加成功（红色则表示失败，需要检查库名是否正确）

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3d5X2hoeHg_size_16_color_FFFFFF_t_70 2][]

3. 在测试套件下创建测试用例

**注：按F5，或 Tools -> Search Keyword 可以搜索关键字用法**

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3d5X2hoeHg_size_16_color_FFFFFF_t_70 3][]

\[例\] 模拟使用Chrome打开百度网页搜索Selenium2Library

（1）使用谷歌浏览器打开 [https://www.baidu.com/][https_www.baidu.com]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3d5X2hoeHg_size_16_color_FFFFFF_t_70 4][]

执行失败，报错如下

20200131 16:09:37.670 :  FAIL :   
WebDriverException: Message: 'chromedriver' executable needs to be in PATH. Please see https://sites.google.com/a/chromium.org/chromedriver/home

**解决**参考 [https://blog.csdn.net/weixin\_41990913/article/details/90936149][https_blog.csdn.net_weixin_41990913_article_details_90936149]，简述如下：

\- 下载chromedriver.exe  
\- 将chromedriver.exe拷贝至谷歌浏览器目录和Python目录  
\- 将谷歌浏览器目录添加到环境变量

step 1 从[https://npm.taobao.org/mirrors/chromedriver/][https_npm.taobao.org_mirrors_chromedriver]下载对应版本的zip包

我的Chrome版本是79.0...于是找了一个接近的版本 [https://npm.taobao.org/mirrors/chromedriver/79.0.3945.36/][https_npm.taobao.org_mirrors_chromedriver_79.0.3945.36]

![20200131165512488.png][]

点开notes.txt确认支持自己的浏览器版本，

*---------ChromeDriver 79.0.3945.36 (2019-11-18)---------  
Supports Chrome version 79*

然后解压下载的zip包，得到 chromedriver.exe

step 2 将chromedriver.exe拷贝到 C:\\...\\Google\\Chrome\\Application 和 C:\\...\\Python\\Python37，路径因个人环境而异

step 3 将谷歌浏览器目录（即上一步的C:\\...\\Google\\Chrome\\Application）添加到环境变量，Win10参考  
控制面板 -> 选择“类别”中的“大图标” -> 选择“系统” -> 点击左侧导航栏“高级系统设置” -> “环境变量” -> 用户变量中选择Path,“编辑” -> “新建”,输入谷歌浏览器目录

然后去RIDE运行就可以成功打开baidu页面

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3d5X2hoeHg_size_16_color_FFFFFF_t_70 5][]

（2）搜索Selenium2Library

使用id找到输入框，同理使用id找到“百度一下”按钮

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3d5X2hoeHg_size_16_color_FFFFFF_t_70 6][]

整个过程的语句如下

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3d5X2hoeHg_size_16_color_FFFFFF_t_70 7][]

以上第6行是一个断言，判断标题是否和预期一致

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3d5X2hoeHg_size_16_color_FFFFFF_t_70 8][]

点击运行按钮，可以看见整个过程，用例执行成功。

附：打开sele\_test.robot，内容如下

*** Settings ***

        open browser    https://www.baidu.com    chrome

        sleep    2
        ${title}    get title

        close browser
