appium 处理webview

折腾了一段时间，无论是模拟器还是真机，driver.contexts都只有NATIVE_APP，无奈放弃切换webview，直接查找定位元素

from time import sleep
 
import pytest
from appium import webdriver
 
class TestWebview:
 
    def setup(self):
        caps = {}
        caps["platformName"] = "Android"
        caps["platformVersion"] = "6.0.1"
        caps["deviceName"] = "127.0.0.1:7555"  # 60c106df0302
        caps["appPackage"] = "io.selendroid.testapp"
        caps["appActivity"] = "io.selendroid.testapp.HomeScreenActivity"
        caps["autoGrantPermissions"] = True
        caps["automationName"] = 'uiautomator2'
 
        self.driver = webdriver.Remote("http://localhost:4723/wd/hub", caps)
        self.driver.implicitly_wait(20)
 
    def test_webview1(self):
        self.driver.find_element_by_id("io.selendroid.testapp:id/buttonStartWebview").click()
        sleep(1)
        self.driver.find_elements_by_class_name("android.widget.EditText")[0].send_keys("haha")
        self.driver.find_elements_by_class_name("android.widget.Button")[1].click()
