如何在 windows x64 上的 python 中记录 selenium webdriver 测试执行

Question

使用 python 绑定 selenium3 webdriver 进行测试自动化，使用 castro 记录执行步骤，但它在 Windows 7 x64 上失败。

是否有任何其他库或模块可用于录制目的

用卡斯特罗编码

from castro import Castro
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from time import sleep

def my_video_record():
    castroObject = Castro(filename="video/mytest.swf")
    castroObject.start()
    firefoxDriver = webdriver.Firefox(executable_path="firefox_geckodriver64bit/geckodriver")
    firefoxDriver.get("https://www.python.org")
    assert "Python" in firefoxDriver.title
    sleep(1)
    firefoxDriver.quit()
    castroObject.stop()

if __name__ == '__main__':
    my_video_record()

但它在我的 Windows7 x64 上引发错误

我不建议使用卡斯特罗。它真的已经过时了，我已经尝试在自己的测试中使用它并且确实可以运行它，但是它太不稳定了。

我目前正在将ffmpeg与screen-capture-recorder（屏幕录制软件）一起使用，它的作用就像一个魅力。它允许您设置帧率、分辨率、比特率以及选择不同的视频编解码器。

代码如下所示：

from subprocess import Popen
from subprocess import call

cmd = 'ffmpeg -y -rtbufsize 2000M -f dshow  -i video="screen-capture-recorder" -s 1920x1080 -b:v 512k -r 20 -vcodec libx264 test.avi'

def terminate(process):
    if process.poll() is None:
        call('taskkill /F /T /PID ' + str(process.pid))

videoRecording = Popen(cmd) # start recording

terminate(videoRecording)   # terminates recording
