+
+
+## 基本的使用过程
+
+AutoLine自动化测试基本过程为:
+
+1. 创建产品
+2. 创建项目
+3. 创建对象集，并创建对象
+4. 创建套件
+5. 创建用例
+6. 创建步骤
+7. 重复3-6
+8. 运行项目
+9. 查看报告
+
+使用AutoLine开源平台进行自动化测试的详细步骤为：
+
+1. 在"产品管理"下新增产品
+
+![创建产品](../images/create_product.png)
+
+2. 在"项目管理"下新增测试项目
+
+![创建项目](../images/create_project.png)
+
+3. 选择2中创建的项目，准备进行规划测试项目
+
+![选择项目](../images/select_project.png)
+
+4. 在项目节点上"右击"鼠标，创建对象集
+
+![创建对象集](../images/create_objects.png)
+
+- 新增环境相关参数数据
+
+- 新增元素定位数据
+
+- 新增百度搜索关键词数据
+
+如下图: 
+
+![数据分类](../images/create_object_category.png)
+
+5. 在对象集节点上"右击"鼠标，创建对象
+
+![创建对象](../images/create_object.png)
+
+在4中的各对象集下创建相应的对象，用于参数化，如下图：
+
+![对象](../images/create_elements.png)
+
+下面我们看下各对象的细节截图：
+
+![](../images/url.png)
+![](../images/browser.png)
+![](../images/kw.png)
+![](../images/btn.png)
+![](../images/word.png)
+![](../images/title.png)
+
+6. 在项目节点上"右击"鼠标，创建套件集
+
+![创建套件](../images/create_suite.png)
+
+- 新增初始化套件
+
+- 新增测试套件
+
+- 新增清理套件
+
+创建完成后如图：
+
+![create_suite_detail](../images/create_suite_detail.png)
+
+每个套件的属性如下图：
+![](../images/init_suite.png)
+![](../images/search_suite.png)
+![](../images/clear_suite.png)
+
+7. 在套件节点上"右击"鼠标，新增测试用例
+
+![case](../images/add_case.png)
+
+用例新增完成如图所示
+
+![cases](../images/add_cases.png)
+
+8. 在用例节点上"右击"鼠标，新增测试步骤，即关键字步骤
+
+![add_step](../images/add_step.png)
+
+详细的step说明：
+
+![step_detail](../images/step_detail.png)
+
+这里以web测试来说明，我们用SeleniumLibrary库提供的关键字：
+
+![seleniumlibrary](../images/selenniumlibrary.png)
+
+
+完整的用例步骤如下：
+![step_list](../images/step_list.png)
+
+下面我们看一下各步骤的详细数据项截图：
+
+
+![open browser](../images/open_browser.png)
+![](../images/max.png)
+![](../images/keyword.png)
+![](../images/sleep.png)
+![](../images/snapshot.png)
+![](../images/click.png)
+![](../images/get_title.png)
+![](../images/assert.png)
+
+9. 在项目节点上"右击"鼠标，选择运行
+![](../images/run.png)
+
+10. 在项目节点上"右击"鼠标，选择查看任务
+
+![查看任务](../images/task_status.png)
+
+11. 查看报告
+
+![报告](../images/report.png)
+
+
+## AutoLine支持哪些关键字
+
+当前已经默认集成了RobotFramework一下关键字，关键字的用法完全同RobotFramework
+
+- 标准库
+1. BuiltIn
+2. Collections
+3. DateTime
+4. Dialogs
+5. OperationSystem
+6. Process
+7. Screenshot
+8. String
+9. Telnet
+10. XML
+
+RobotFramework标准库关键字文档：
+http://robotframework.org/robotframework/#standard-libraries
+
+- 第三方库
+1. SeleniumLibrary
+   
+作用: 支持web UI测试
+关键字文档: http://robotframework.org/SeleniumLibrary/SeleniumLibrary.html
+
+2. Appium   
+
+作用: 支持APP移动端UI测试（android&ios）
+关键字文档: http://serhatbolsu.github.io/robotframework-appiumlibrary/AppiumLibrary.html
+
+3. Requests   
+
+功能: 支持HTTP接口测试
+关键字文档: https://github.com/bulkan/robotframework-requests/#readme
+
+## Cron表达式说明
+
+在创建项目时，需要输入cron表达式以实现定时的计划任务，cron表达式格式同jenkins，格式为：
+
+> minute, hour, day, month, day_of_week
+
+默认值为: * * * * * 
+
+minute - 用于配置分钟
+hour - 用于配置小时
+day - 用于配置天
+month - 用于配置月
+day_of_week - 用于配置周里的天数
+
+### 常用cron表达式
+
+*/30 * * ? 每30分钟执行一次    
+0 12 * * ? 每天中午12点触发   
+15 10 * * ? 每天上午10:15触发     
+15 10 L * ?  每月最后一日的上午10:15触发   
+15 10 ? * 6L 每月的最后一个星期五上午10:15触发   
+0 1 * * ?  每天凌晨1点执行一次
+
+更多的cron表达式用法 请直接看官方文档吧，自己去找文档
