控制客户端，返回超时问题 ​

现象 ​

执行需要与加域客户端交互的测试用例，当脚本代码完成发送后，操作客户端时，zerorpc通信超时：

分析 ​

1、进入加域客户端，手动启动远程服务，提示Could not open X display：

shell
(youqu) 12345@uos-PC:~/youqu/src/remotectl$ python3 _remote_other_ctl.py 
No protocol specified
Unable to init server: Could not connect: Connection refused
No protocol specified
Unable to init server: 无法连接：Connection refused
No protocol specified

(_remote_other_ctl.py:21887): dbind-WARNING **: 10:00:10.002: Could not open X display

2、查看当前登录终端，发现有多个 x 服务在运行：

shell
$ $ who
uos      tty1         2024-07-30 16:50 (:0)
12345    tty2         2024-07-30 17:04 (:1)
12345    pts/0        2024-07-31 09:59 (10.8.11.74)

3、注销 x 服务为 0 的用户，再次尝试依旧复现，查询后发现加域账户依旧虽然为第一个 x 服务，但是标识依旧是 :1

shell
$ $ who
12345    tty2         2024-07-30 17:04 (:1)
12345    pts/0        2024-07-31 09:59 (10.8.11.74)

解决 ​

重启终端系统，只登录加域账户，问题消失

​

控制客户端，无法找到资源问题 ​

现象 ​

执行用例时，服务端网页自动化执行正常，进行客户端断言时，找不到资源（图片资源）

分析 ​

1、找不到资源，查看客户端 youqu 项目的自动化应用项目是否存在对应资源，发现整个 youqu 项目没有同步到客户端

2、执行前有进行过手动删除 youqu 的动作，重新执行时，调试发现没有进行重新发送

python
# youqu/src/remotectl/_base.py
def _transfer_appname(ip, password, user, transfer_appname):
    os.system(
        f"sshpass -p '{password}' rsync -av -e ssh --exclude='__pycache__' "
        f"{conf.APPS_PATH}/{transfer_appname} {user}@{ip}:~/{client_project_path}/apps/"
    )

3、继续断点调试，发现逻辑为如果存在远端远程服务进程，则不进行文件同步

python
# youqu/src/remotectl/_base.py
def check_rpc_started(filename):
			……
            _base_env_check()
            if transfer_appname:
                _transfer_appname(ip, password, user, transfer_appname)
            tool_status = os.popen(
                f'''{_ssh(ip, password, user)} "ps -aux |  grep {filename} | grep -v grep"'''
            ).read()
            if not tool_status:
                _transfer_to_client(ip, password, user)
                _start_client_service(ip, password, user, filename)
            if restart_service:
                _restart_client_service(ip, password, user, filename)
            res = func(*args, **kwargs)
			……

4、查看客户端服务进程，文件虽然不存在，但是进程依旧存在

shell
12345@uos-PC:~$ ps aux|grep remote
12345     4648  0.5  2.2 725052 183048 ?       SLsl 10:03   0:14 /home/12345@udcp/youqu/.venv/bin/python _remote_other_ctl.py
12345     5123  0.0  1.9 700436 155644 ?       SLsl 10:03   0:02 /home/12345@udcp/youqu/.venv/bin/python _remote_dogtail_ctl.py
12345    18070  0.0  0.0  13820   888 pts/1    S+   10:52   0:00 grep remote

解决 ​

杀掉原进程，重新执行，报错消失
