selenium 总结篇,常见方法和页面元素的操作
今天,总结一下selenium怎么操作web页面常见的元素。
主要有:
- 上传
- alter dialog
- prompt dialog
- confirm dialog
- select list
- radio box
- input box
- checkBox
测试页面如下:
selenium 最核心的技巧是WebElement的识别和定位
selenium总共有八种定位方法
- By.id() 通过id定位
- By.name() 通过name 定位
- By.xpath() 通过xpath定位
- By.className() 通过className定位
- By.cssSelector() 通过CSS 定位
- By.linkText() 通过linkText
- By.tagName() 通过tagName
- By.partialLinkText() 通过匹到的部分linkText
目前,使用比较多的是cssSelector和xpath,因为一个页面中Id name className tagName LinkText等比较容易重复 不容易 确定唯一
接下来会有具体的例子来演示如何定位
上传文件
一般,上传页面如果是input,像这样的,可以使用sendkeys
首先,这里使用xpath定位到该元素,然后使用sendKeys即可,sendKeys send你要上传的文件的绝对路径
1 //td/input[@type='file']
也可以使用cssSelector,关于xpath和cssSelector更多知识,以后会做一些专题
1 td>input[type='file']
如何验证你写的xptah/cssSelector是正确的呢?
有以下几种方法:
- F12 ,使用浏览器的console ,xpath使用$x() function,css使用 $() function
- 使用第三方插件firebug
- 使用selenium IDE
alert对话框
细分三种,Alert,prompt,confirm
Selenium有以下方法:
Alert alert =driver.switchTo().alert();
1. driver.switchTo().alert(); 获取alert
2. alert.accept(); 点确定
3. alert.dismiss(); 点取消
4. alert.getText();获取alert的内容
select菜单
select也是比较常见的,selenium封装了以下方法
创建select
WebElement selector = driver.findElement(By.id("Selector")); Select select = new Select(selector);
选择select的option有以下三种方法
- selectByIndex(int index) 通过index
- selectByVisibleText(String text) 通过匹配到的可见字符
- selectByValue(String value) 通过匹配到标签里的value
WebElement selector = driver.findElement(By.id("Selector")); Select select = new Select(selector); select.selectByIndex(3); select.selectByVisibleText("桃子"); select.selectByValue("apple");
输入框
输入框就比较简单了,不再多说
sendKeys()输入内容
clear() 清空
单选框(RadioBox)
单选框可以有获取状态,是否被选中
radioBox.isSelected();
是否enable
radioBox.isEnabled()
使用click方法选中
复选框(checkBox)
复选框和单选框基本差不多,此处略
超链接
超链接比较常见,一般都是标签a
<a href="http://www.cnblogs.com/tobecrazy/" >Copyright 2015 to be crazy </a>
一般使用click方法
这里我们了解一下浏览器打开超链接时,如果是chrome,点超链接的同时按下Ctrl会打开新标签,按下shift会打开新窗口
这里单讲一下不同窗口切换.
selenium有两个关于获取窗口的方法:
1. driver.getWindowHandle(); 返回的是字符串,获取当前窗口的句柄
2. driver.getWindowHandles(); 返回的是 Set<String> ,获取所有窗口
如果你想在窗口之间切换
driver.switchTo().window(window);
小技巧: 如何滚动到你定位的元素
这里使用java script
// scroll to mylink JavascriptExecutor scroll = (JavascriptExecutor) driver; scroll.executeScript("arguments[0].scrollIntoView();", myLink);
接下来是所有测试代码:
