一、前置说明
测试环境：
- appium版本：2.2.2
- Appium-Python-Client： 3.1.0
- 微信版本：8.0.43
在使用下面代码测试启动微信时，一直不能把微信启动起来：
import time import pytest from driver.appium.manager import AppiumServersManager from driver.appium.driver import WebDriver from libs.cmd_util import cmd def setup_module(): import logging logging.basicConfig(level=logging.DEBUG) # 启动 appium server server_manager = AppiumServersManager(tail_log=True) server_manager.start() @pytest.fixture(scope='module') def driver(): appium_server_url = 'http://localhost:4723' capabilities = { "platformName": "Android", "automationName": "uiautomator2", "deviceName": "9YS0220306003185", "appPackage": "com.tencent.mm", "appActivity": ".ui.LauncherUI", "noReset": "true" } driver = WebDriver(command_executor=appium_server_url, capabilities=capabilities) yield driver driver.quit() def test_wechat(driver): time.sleep(2) driver.find_element('xpath', "//*[@text='通讯录']").click()
从appium server中查找启动微信app的日志，如下：
2023-12-09 23:03:38:762 [AndroidDriver] Screen already unlocked, doing nothing 2023-12-09 23:03:38:762 [AndroidUiautomator2Driver@02b1 (42be6406)] Starting 'com.tencent.mm/.ui.LauncherUI and waiting for 'com.tencent.mm/.ui.LauncherUI' 2023-12-09 23:03:38:762 [ADB] Getting IDs of all 'com.tencent.mm' processes 2023-12-09 23:03:38:762 [ADB] Running 'D:\ProgramFiles\Android\android-sdk\platform-tools\adb.exe -P 5037 -s 9YS0220306003185 shell pgrep -f \(\[\[:blank:\]\]\|\^\)com\.tencent\.mm\(\[\[:blank:\]\]\|\$\)' 2023-12-09 23:03:38:857 [AndroidUiautomator2Driver@02b1 (42be6406)] 'com.tencent.mm' is already running and noReset is enabled.

其中有这么一句：
2023-12-09 23:03:38:857 [AndroidUiautomator2Driver@02b1 (42be6406)] ‘com.tencent.mm’ is already running and noReset is enabled. Set forceAppLaunch capability to true if the app must be forcefully restarted on session startup.
二、解决办法
根据日志提示，尝试在 capabilities 添加 "forceAppLaunch": "true" 之后，顺利启动微信。
import time import pytest from driver.appium.manager import AppiumServersManager from driver.appium.driver import WebDriver from libs.cmd_util import cmd def setup_module(): import logging logging.basicConfig(level=logging.DEBUG) # 启动 appium server server_manager = AppiumServersManager(tail_log=True) server_manager.start() @pytest.fixture(scope='module') def driver(): appium_server_url = 'http://localhost:4723' capabilities = { "platformName": "Android", "automationName": "uiautomator2", "deviceName": "9YS0220306003185", "appPackage": "com.tencent.mm", "appActivity": ".ui.LauncherUI", "noReset": "true", "forceAppLaunch": "true", # 注意：加上这个参数，可以顺利启动微信 } driver = WebDriver(command_executor=appium_server_url, capabilities=capabilities) yield driver driver.quit() def test_wechat(driver): time.sleep(2) driver.find_element('xpath', "//*[@text='通讯录']").click()
