NullPointerException with Simultaneous Screencaptures on MAC and PC with Parallel Selenium Tests with TestNG

Question

I'm trying to get screencaptures for failed selenium tests running in parallel on a MAC node and a PC node using selenium grid. The tests run, but fails to create the screencaptures. I'm getting a nullpointerexception. Can someone advise me how to fix this? Thanks.

java.lang.NullPointerException

问题是当您创建Screenshot的实例时，驱动程序仍然为null，因此您需要在浏览器初始化后创建其实例。
