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:
1 <html> 2 <head> 3 <title>selenium处理基本页面元素</title> 4 <style type="text/css"> 5 table{font-size:26;text-align:center;width:80%;border-collapse:collapse;margin:auto} 6 table th{background: #aff} 7 .display{color:red} 8 .widgetStyle{text-align:left;padding-left:100px} 9 </style> 10 <script language= "javascript" type="text/javascript"> 11 function clickbutton(flag) 12 { 13 if (flag == 1) alert("测试alert对话框"); 14 if (flag == 2) 15 { 16 var name=prompt("测试prompt对话框",""); 17 if (name!=null && name!="") 18 { 19 //document.write(name); 20 alert(name); 21 } 22 } 23 if (flag == 3) 24 { 25 var r=confirm('测试confirm对话框', '测试confirm对话框?',"测试结果:") 26 if (r==true) 27 { 28 //document.write("You pressed OK!") 29 alert("You pressed OK!"); 30 } 31 else 32 { 33 //document.write("You pressed Cancel!") 34 35 alert("You pressed Cancel!"); 36 } 37 } 38 if (flag == 4) 39 40 alert(document.getElementById("edit").value); 41 42 43 } 44 45 46 47 48 function getOptions() 49 { 50 var x=document.getElementById("Selector"); 51 var y=x.options[x.selectedIndex].text 52 // document.write(y); 53 alert(y); 54 } 55 </script> 56 </head> 57 58 <body> 59 <center> 60 </br> 61 <div> 62 <p> 63 64 <div class="text" style="font-size:36;text-align:center"><b>seleniun处理基本元素</b></div> 65 </p> 66 <hr> 67 </div> 68 <p> 69 <table cellpadding="10" cellspacing="0" border="2"> 70 <thead> 71 <tr> 72 <th width=20% class="widgetleft">测试内容</th> 73 <th width=80% class="widgetStyle">页面基本元素</th> 74 </tr> 75 </thead> 76 77 78 <tr> 79 <td>文件上传</td> 80 <td><input type="file" name="attach[]" /></td> 81 </tr> 82 83 <tr> 84 <td>alter对话框</td> 85 <td> 86 <input type="button" name="alterbutton" value="测试alter对话框" onclick = "clickbutton(1);" /> 87 </td> 88 </tr> 89 90 <tr> 91 <td>prompt对话框</td> 92 <td> 93 <input type="button" name="promptbutton" value="测试prompt对话框" onclick = "clickbutton(2);" /> 94 </td> 95 </tr> 96 97 <tr> 98 <td>confirm对话框</td> 99 <td> 100 <input type="button" name="confirmbutton" value="测试confirm对话框" onclick = "clickbutton(3);" /> 101 </td> 102 </tr> 103 <tr> 104 <td>select菜单</td> 105 <td> 106 <select id="Selector"> 107 <option value="apple" index="1" >苹果</option> 108 <option value="peach" index="2" >桃子</option> 109 <option value="banana" index="3" >香蕉</option> 110 <option value="orange" index="4">桔子</option> 111 <option value="grape" index="5">葡萄</option> 112 <option value="mango" index="6">芒果</option> 113 </select> 114 <br /><br /> 115 <input type="button" id="showSelectResult" name="showSelectResult" onclick="getOptions()" value="选择结果"> 116 </td> 117 </tr> 118 119 <tr> 120 <td>文本框</td> 121 <td> 122 <input type="text" name="edit" id="edit" value="" /> 123 <input type="button" name="submit" value="submit" onclick = "clickbutton(4);"/> 124 </td> 125 </tr> 126 127 <tr> 128 <td>RadioBox</td> 129 <td class="widgetStyle"> 130 <label> 131 Which is your favourite company?

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:
