APP自动化测试-11.webview技术原理

前言

根据日志，简单记录webview运行的机制

脚本：

from time import sleep

import pytest
from appium import webdriver
from appium.webdriver.common.appiumby import AppiumBy
from selenium.webdriver.common.by import By


class TestHybrid:

    def setup(self):
        desired_caps = {
            "platformName": "android",
            "appium:deviceName": "b1f37e8e",
            "appium:appPackage": "io.appium.android.apis",
            "appium:appActivity": ".ApiDemos",
            "chromedriverExecutableDir": "/Users/gaozeyu/tools/chromedriverdir",
            "chromedriverChromeMappingFile": "/Users/gaozeyu/PycharmProjects/test_appium/testcase/mapping.json"
        }

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

        # 设置隐式等待
        self.driver.implicitly_wait(10)

    def teardown(self):
        self.driver.quit()

    def test_hybrid(self):
        sleep(3)
        self.driver.find_element(AppiumBy.ACCESSIBILITY_ID, 'Views').click()
        webview = "WebView"
        self.driver.find_element(AppiumBy.ANDROID_UIAUTOMATOR, f'new UiScrollable(new UiSelector().scrollable(true).instance(0)).scrollIntoView(new UiSelector().text("{webview}").instance(0));').click()

        print(self.driver.contexts)
        # 切换上下文，由原生切换至webview
        self.driver.switch_to.context(self.driver.contexts[-1])
        self.driver.find_element(By.XPATH, '//*[@id="i_am_a_textbox"]').send_keys("this is a test message")

        # 窗口切换
        print(self.driver.window_handles)
        self.driver.find_element(By.XPATH, '//*[@id="i am a link"]').click()
        print(self.driver.window_handles)

        sleep(3)

        if __name__ == 'main':
            pytest.main()

一、获取webview

第一次调用webview脚本代码：

print(self.driver.contexts)
