有没有办法找到任何Windows应用程序的启动时间？

问题描述

假设我正在使用VLC Player，并且我想计算使用python启动所需的时间，有什么办法吗？

我尝试过winium自动化，但是元素加载太慢。我想获得应用程序的启动时间，并在4-5秒内启动，而winium通常花费更多的时间来查找元素的位置。

如果有人可以通过后端自动化提出更好的建议，请发表评论。

解决方法

如果我理解正确，那么您需要查找从执行该应用程序到窗口出现之间的时间。您可以使用pygetwindow库来实现。这是代码：

    import pygetwindow as pw
    import time
    # here's code that executing the program,but i just put comment
    start = time.time()
    while 1: # waiting until window appears
        # getWindowsWithTitle method returns empty list if it didn't found any windows with this name
        if pw.getWindowsWithTitle('VLC'): #if it founds the window,loop will break
            break
    stop = time.time()
    result = stop - start # result is time in seconds (type float)

编辑

您还可以通过检查窗口数量是否发生变化来检测应用程序的启动。

    import pygetwindow as pw
    import time
    starting_amount = len(pw.getAllWindows()) # amount of windows
    # here's code that executing the program,but i just put comment
    start = time.time()
    while 1: # waiting until window appears
        if len(pw.getAllWindows()) > starting_amount: #if amount of windows is bigger than it was before we executed the program
            break
    stop = time.time()
    result = stop - start # result is time in seconds (type float)

这应该适用于LD Player
