appium+python自动化34-获取元素属性

前言

在做断言的时候，我们往往需要先获取目标元素的某些属性值，拿来判断，比如登录后，如何判断登录成功了呢？可以通过登录后获取账号的名称（元素的text属性）来判断。

一、获取text

``` # coding:utf-8 from appium import webdriver from time import sleep desired_caps = { 'platformName': 'Android', 'deviceName': '127.0.0.1:62001', 'platformVersion': '4.4.2', 'appPackage': 'com.baidu.yuedu', 'appActivity': 'com.baidu.yuedu.splash.SplashActivity', 'noReset': 'true', 'resetKeyboard': 'true', 'unicodeKeyboard': 'true' } driver = webdriver.Remote('http://127.0.0.1:4723/wd/hub', desired_caps) # 等主页面activity出现 driver.wait_activity(".base.ui.MainActivity", 10) # 点取消升级 driver.find_element_by_id("com.baidu.yuedu:id/negativeUpgrade").click() # 获取text t1 = driver.find_element_by_id("com.baidu.yuedu:id/lefttitle").text print(t1) ``` 二、tag_name 1.tag_name实质上是获取class属性 ``` # 获取tag_name t2 = driver.find_element_by_id("com.baidu.yuedu:id/lefttitle").tag_name print(t2) ```

2.打印结果：android.widget.TextView 三、get_attribute 1.获取content-desc属性，这里注意了，如果content-desc属性为空，那么获取的就是text属性，不为空获取的才是content-desc属性 2.content-desc属性为空,打印结果：书架 ``` # content-desc为空，获取的是text t3 = driver.find_element_by_id("com.baidu.yuedu:id/lefttitle").get_attribute("name") print(t3) ```

3.content-desc属性不为空，打印结果：百度阅读 ``` # content-desc t4 = driver.find_element_by_id("com.baidu.yuedu:id/fragment_banner").get_attribute("name") print t4 ```

4.id,calss,text属性获取 ``` # id t5 = driver.find_element_by_id("com.baidu.yuedu:id/lefttitle").get_attribute("resourceId") print(t5) # class t6 = driver.find_element_by_id("com.baidu.yuedu:id/lefttitle").get_attribute("className") print(t6) # text t7 = driver.find_element_by_id("com.baidu.yuedu:id/lefttitle").get_attribute("text") print(t7) ``` 5.其它属性获取，注意这里并不是所有的都可以获取，一些标准的属性是可以获取到的 ``` # checkable t8 = driver.find_element_by_id("com.baidu.yuedu:id/lefttitle").get_attribute("checkable") print t8 # clickable t9 = driver.find_element_by_id("com.baidu.yuedu:id/lefttitle").get_attribute("clickable") print t9 ```

四、size和location 1.获取size，返回的是字典，如：{'width': 84, 'height': 84} 2.获取location，返回的是字典，如：{'y': 38, 'x': 192} ``` # size t10 = driver.find_element_by_id("com.baidu.yuedu:id/lefttitle").size print t10 # location t11 = driver.find_element_by_id("com.baidu.yuedu:id/lefttitle").location print t11 ``` 五、参考代码 ``` # coding:utf-8 from appium import webdriver desired_caps = { 'platformName': 'Android', 'deviceName': '127.0.0.1:62001', 'platformVersion': '4.4.2', 'appPackage': 'com.baidu.yuedu', 'appActivity': 'com.baidu.yuedu.splash.SplashActivity', 'noReset': 'true', 'resetKeyboard': 'true', 'unicodeKeyboard': 'true' } driver = webdriver.Remote('http://127.0.0.1:4723/wd/hub', desired_caps) # 等主页面activity出现 driver.wait_activity(".base.ui.MainActivity", 10) # 点取消升级（版本不要升级了） driver.find_element_by_id("com.baidu.yuedu:id/negativeUpgrade").click() # 获取text t1 = driver.find_element_by_id("com.baidu.yuedu:id/lefttitle").text print(t1) # 获取tag_name t2 = driver.find_element_by_id("com.baidu.yuedu:id/lefttitle").tag_name print(t2) # content-desc为空，获取的是text t3 = driver.find_element_by_id("com.baidu.yuedu:id/lefttitle").get_attribute("name") print(t3) # content-desc t4 = driver.find_element_by_id("com.baidu.yuedu:id/fragment_banner").get_attribute("name") print t4 # id t5 = driver.find_element_by_id("com.baidu.yuedu:id/lefttitle").get_attribute("resourceId") print(t5) # class t6 = driver.find_element_by_id("com.baidu.yuedu:id/lefttitle").get_attribute("className") print(t6) # text t7 = driver.find_element_by_id("com.baidu.yuedu:id/lefttitle").get_attribute("text") print(t7) # checkable t8 = driver.find_element_by_id("com.baidu.yuedu:id/lefttitle").get_attribute("checkable") print t8 # clickable t9 = driver.find_element_by_id("com.baidu.yuedu:id/lefttitle").get_attribute("clickable") print t9 # size t10 = driver.find_element_by_id("com.baidu.yuedu:id/lefttitle").size print t10 # location t11 = driver.find_element_by_id("com.baidu.yuedu:id/lefttitle").location print t11 ```
