1.什么是selenium？
Selenium 是支持web 浏览器自动化的一系列工具和 库的综合项目。 它提供了扩展来模拟用户与浏览器的交互，用于扩展浏览器分配的分发 服务器， 以及用于实现W3C WebDriver 规范 的基础结构， 该规范允许您为所有主要Web 浏览器编写可互换的代码。 Selenium 不仅仅是一个工具或 API, 它还包含许多工具.
WebDriver
如果您开始使用桌面网站测试自动化, 那么您将使用 WebDriver APIs. WebDriver 使用浏览器供应商提供的浏览器自动化 API 来控制浏览器和运行测试. 这就像真正的用户正在操作浏览器一样. 由于 WebDriver 不要求使用应用程序代码编译其 API, 因此它本质上不具有侵入性. 因此, 您测试的应用程序与实时推送的应用程序相同.
Selenium IDE
Selenium IDE (Integrated Development Environment 集成 开发环境) 是用来开发 Selenium 测试用例的工具. 这是一个易于使用的 Chrome 和 Firefox 浏览器扩展, 通常是开发测试用例最有效率的方式. 它使用现有的 Selenium 命令记录用户在浏览器中的操作, 参数由元素的上下文确定. 这不仅节省了开发时间, 而且是学习 Selenium 脚本语法的一种很好的方法.
Grid
Selenium Grid允许您在不同平台的不同机器上运行测试用例. 可以本地控制测试用例的操作, 当测试用例被触发时, 它们由远端自动执行. 当开发完WebDriver测试之后, 您可能需要在多个浏览器和操作系统的组合上运行测试. 这就是 Grid 的用途所在.
2.代码工程
实验目标
- 打开chrome，自动输入Google网页并进行搜索
- 对搜索结果截图并保存
- 关闭浏览器
