把scrcpy录屏方法封装在conftest.py文件里，在本地直接运行可以成功，但是放在jenkins上运行报错
Jenkins报错信息：

scrcpy录屏方法封装：

@pytest.fixture(scope="class", autouse=True)
def record():
    cmd = shlex.split("scrcpy --record mp.mp4")
    p = subprocess.Popen(cmd, shell=False, stdout=subprocess.PIPE, stderr=subprocess.STDOUT)
    yield
    #os.kill(p.pid, signal.CTRL_C_EVENT)
    # os.popen('taskkill.exe/pid:'+str(p.pid))
    os.kill(p.pid, signal.SIGTERM)

    sleep(1)
    with open("mp.mp4", "rb") as f:
        content = f.read()
    allure.attach(content, attachment_type=allure.attachment_type.MP4)

请老师帮忙查看下是哪里的问题，如何在Jenkins上成功运行，谢谢

2

感觉试试看shell=True

3

改成shell=True之后case可以运行，但是录屏还是会报错，之前shell=False时，case都运行不了

4

录屏还是那个文件找不到的错误吗

5

不是了，这次错误是拒绝访问

你看看你那里有没有生成mp.mp4，这个权限问题是你杀进程，没有权限，可以有其他办法解决

7

我这边在workspace生成.mp4文件，但是打不开

8

没有生成mp.mp4，就在本地运行的时候可以看到scrcpy打开了，但是用Jenkins运行，scrcpy没有打开

9

就是用Jenkins运行的时候，没有生成.mp4的文件，但它可以把我本地原有的.mp4文件放进allure报告里，感觉就是放到Jenkins运行的时候scrcpy这个录屏用的软件打不开

10

打开文件前，加个sleep

11

没听懂 生成的是文件 怎么sleep
