简单的对象定位 - shiguang1120/webdriver_guide GitHub Wiki
测试对象的定位和操作是webdriver的核心内容,其中操作又是建立在定位的基础之上,因此对象定位就越发显得重要了。
定位对象的目的一般有下面几种
- 操作对象
- 获得对象的属性,如获得测试对象的class属性,name属性等等
- 获得对象的text
- 获得对象的数量
webdriver提供了一系列的对象定位方法,常用的有以下几种
- id
- name
- class name
- link text
- partial link text
- tag name
- xpath
- css selector
<html>
<head>
<meta http-equiv="content-type" content="text/html;charset=utf-8" />
<title>Form</title>
<script type="text/javascript" async="" src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<link href="http://netdna.bootstrapcdn.com/twitter-bootstrap/2.3.2/css/bootstrap-combined.min.css" rel="stylesheet" />
<script src="http://netdna.bootstrapcdn.com/twitter-bootstrap/2.3.2/js/bootstrap.min.js"></script>
</head>
<body>
<h3>simple login form</h3>
<form class="form-horizontal">
<div class="control-group">
<label class="control-label" for="inputEmail">Email</label>
<div class="controls">
<input type="text" id="inputEmail" placeholder="Email" name="email">
</div>
</div>
<div class="control-group">
<label class="control-label" for="inputPassword">Password</label>
<div class="controls">
<input type="password" id="inputPassword" placeholder="Password" name="password">
</div>
</div>
<div class="control-group">
<div class="controls">
<label class="checkbox">
<input type="checkbox"> Remember me
</label>
<button type="submit" class="btn">Sign in</button>
<a href="#">register</a>
</div>
</div>
</form>
</body>
</html>
from selenium import webdriver
from time import sleep
import os
if 'HTTP_PROXY'in os.environ: del os.environ['HTTP_PROXY']
dr = webdriver.Chrome()
file_path = 'file:///' + os.path.abspath('form.html')
print file_path
dr.get(file_path)
# by id
dr.find_element_by_id('inputEmail').click()
# by name
dr.find_element_by_name('password').click()
# by tagname
print dr.find_element_by_tag_name('form').get_attribute('class')
# by class_name
e = dr.find_element_by_class_name('controls')
dr.execute_script('$(arguments[0]).fadeOut().fadeIn()', e)
sleep(1)
# by link text
link = dr.find_element_by_link_text('register')
dr.execute_script('$(arguments[0]).fadeOut().fadeIn()', link)
sleep(1)
# by partial link text
link = dr.find_element_by_partial_link_text('reg')
dr.execute_script('$(arguments[0]).fadeOut().fadeIn()', link)
sleep(1)
# by css selector
div = dr.find_element_by_css_selector('.controls')
dr.execute_script('$(arguments[0]).fadeOut().fadeIn()', div)
sleep(1)
# by xpath
dr.find_element_by_xpath('/html/body/form/div[3]/div/label/input').click()
sleep(2)
dr.quit()
上面例子里由于html文件中引用了jquery,所以在执行js时可以使用jquery的$()及fadeIn()等方法。如果你测试的页面没用包含jquery的话,这些方法是无效的。
