Appium Appium v1.4.16 上 安卓真机测试混合 App 时 clear 方法无法工作，怎么解决？

appium · 2016年03月01日 · 最后由 黑水 回复于 2016年03月02日 · 1960 次阅读

环境：

Appium： 1.4.16
selenium： 2.52.0
安卓版本 5.1.1
测试app：官方selendroid-test-app.apk

官方 selendroid-test-app.apk
对该 App 测试官方代码样例在地址
官方混合应用文档说明：指导说明
我修改后的代码：

PLATFORM_VERSION = '5.1.1'
class AndroidWebViewTests(unittest.TestCase):

    def setUp(self):
        app = os.path.abspath(
                os.path.join(os.path.dirname(__file__),
                             '../../apps/selendroid-test-app.apk'))
        desired_caps = {
            'app': app,
            'appPackage': 'io.selendroid.testapp',
            'appActivity': '.HomeScreenActivity',
            'platformName': 'Android',
            'platformVersion': PLATFORM_VERSION,
            'deviceName': 'emulator-22'
        }


        if (PLATFORM_VERSION != '4.4'):
            desired_caps['automationName'] = 'selendroid'

        self.driver = webdriver.Remote('http://localhost:4723/wd/hub', desired_caps)

    def test_webview(self):
        if (PLATFORM_VERSION == '4.4'):
            button = self.driver.find_element_by_accessibility_id('buttonStartWebviewCD')
        else:
            button = self.driver.find_element_by_name('buttonStartWebviewCD')
        button.click()

    sleep(2)
    self.driver.switch_to.context('WEBVIEW_0') # NATIVE_APP
    print self.driver.page_source
        input_field = self.driver.find_element_by_id('name_input')
        sleep(1)
    # input_field.click()
    sleep(1)
        input_field.clear()
    # error due to clear method 
    input_field.send_keys('Appium User')
        input_field.submit()

切到 web 视图后 driver.page_source 输出为：

<html xmlns=\"http://www.w3.org/1999/xhtml\"><head><title>Say Hello Demo</title></head><body>Hello, can you please tell me your name?<form name=\"myform\" action=\"http://localhost:4450/sayhello\" method=\"get\"><div align=\"center\"><br /><br /><input type=\"text\" id=\"name_input\" name=\"name\" size=\"25\" value=\"Enter your name here!\" /><br /><p>Prefered Car:<br /><select name=\"car\"><option value=\"volvo\">Volvo</option><option value=\"mercedes\">Mercedes</option><option value=\"audi\">Audi</option></select></p><br /><input type=\"submit\" value=\"Send me your name!\" /><br /></div></form></body></html>

从 driver.page_source 结果中，可以看出 web 视图中具有 id 值为 name_input 的表单（value="Enter your name here!"），而且可以定位到该元素，为什么说可以定位到该元素，因为，把调用 clear 的代码

input_field.clear()

注释掉后测试就正常了。那么，如何解决调用 clear 方法清理表单值的异常？

在补充一条记录

/XXXXXXX/python2.7/site-packages/selenium/webdriver/remote/webelement.py:89: in clear
    self._execute(Command.CLEAR_ELEMENT)
/XXXXXXX/python2.7/site-packages/selenium/webdriver/remote/webelement.py:469: in _execute
    return self._parent.execute(command, params)
/XXXXXXX/python2.7/site-packages/selenium/webdriver/remote/webdriver.py:201: in execute
    self.error_handler.check_response(response)

这是不是提示 selenium 的问题？

想到两次调用

send_keys()

方法，第一次发送空字符串，第二次再发自定义字符串，结果不是我的预期：它把空字符串也输入到表单中了😭

陈恒捷 #3 · 2016年03月01日

我被你搞混乱了，到底是 clear() 方法有问题还是 click() 有问题？

你的标题说 click 不行，但正文明显是说 clear 报错。。。

#3 楼 @chenhengjie123 已修改。是 clear 方法清楚表单值时异常，多谢指出。您有什么高见？

黑水 #5 · 2016年03月02日

为什么代码里注释这行# input_field.click()
log 里看还是 click 了呢
