Appium 求助！使用 appium2.0 版本时，driver.close() 和.quit() 关闭应用失效的问题！

最近在使用 appium2 编写安卓自动化，appium2 的会话配置中有一项 appium:noReset: 默认为 false，即启动应用默认重置应用状态。为了不每次启动应用都要重新登陆然后点击各种弹窗，所以这一项我一般设置为 true。那么问题来了，我初始化 driver 写在一个 fixture 里（代码最下面），我想每次结束一个条用例就会执行这个 fixture 的后置处理即关闭应用，目的是在执行下一条用例时启动就会在首页（统一初始页面）；但是当 appium:noReset: true 时无论是 quit() 还是 close() 都会失败，好像是因为和 appium:noReset: true 产生冲突，即 noReset: true 不让你重置关闭也不行！；当然把 noReset: 设置为 false，倒是可以关闭了，但是下次启动应用直接重置应用了，要中登陆开始执行了！

语言组织得有点乱，总的来说我的目的是：在不重置的应用的情况下关闭应用，但是 appium2.0 是必须设置为每次重置应用才能让关闭应用方法生效！

这把我搞的好烦，求各位大佬指点迷津！

@pytest.fixture()
def init_driver(request):
    # 前置
    driver = webdriver.Remote(appium_server_url, options=AppiumOptions().load_capabilities(capabilities))

    yield driver
    # 后置
    driver.close()
    # driver.quit()

现在用这的人少了，大部分都上云测，录脚本了

不能关闭，执行这条 driver.close() 报错是咋样的？

把你的 capabilities 贴出来看看

这是我的 caps 其实主要就是 appium:noReset: false

你这里面，明显是 close 这个方法是没有的呀，参考：https://github.com/appium/python-client/blob/master/appium/webdriver/mobilecommand.py

这里面没有 close.

/Library/Frameworks/Python.framework/Versions/3.10/lib/python3.10/site-packages/selenium/webdriver/remote/webdriver.py:459: in close
    self.execute(Command.CLOSE)

你用的是的 remote，这里是有 CLOSE 的，参见：https://github.com/SeleniumHQ/selenium/blob/trunk/py/selenium/webdriver/remote/command.py

这里其实是对不上的，比较奇怪。不过 appium python client 里面用 remote 也只是用了 NEW_SESSION、FIND_ELEMENT(s)、GET_ELEMENT_ATTRIBUTE、FIND_CHILD_ELEMENT(s)、SEND_KEYS_TO_ELEMENT。本质上 appium-uiautomator2-server 里面没有实现那就应该没有了。

quit 倒是有，

remote 里面：

Command.QUIT: ("DELETE", "/session/$sessionId"),

uiautomator2 driver 里面里面：

async deleteSession () {
  this.log.debug('Deleting UiAutomator2 server session');
  // rely on jwproxy's intelligence to know what we're talking about and
  // delete the current session
  try {
    await this.jwproxy.command('/', 'DELETE');
  } catch (err) {
    this.log.warn(`Did not get confirmation UiAutomator2 deleteSession worked; ` +
        `Error was: ${err}`);
  }
}

对应服务端的处理：
https://github.com/appium/appium-uiautomator2-server/blob/master/app/src/main/java/io/appium/uiautomator2/server/AppiumServlet.java


@Override
public void handleHttpRequest(IHttpRequest request, IHttpResponse response) {
    BaseRequestHandler handler = null;
    if ("GET".equals(request.method())) {
        handler = findMatcher(request, getHandler);
    } else if ("POST".equals(request.method())) {
        handler = findMatcher(request, postHandler);
    } else if ("DELETE".equals(request.method())) {
        handler = findMatcher(request, deleteHandler);
    }
    if (handler != null) {
        handleRequest(request, response, handler);
    }
}
