Geckodriver 突然开始失败

Question

Driver: geckodriver 0.19.1.

OS Name: Microsoft Windows 10 Pro for Workstations Version: 10.0.17134 Build 17134.

Firefox: 63.0 (64-bit).

Running tests using TestNG version 6.14.0.

This was working fine until this morning. There are no perceivable Windows updates.

Today, the browser flashes open & disappears again. The following output is displayed:

I can't tell when Firefox last updated itself, but it may be the culprit. Any ideas?

Answer 1
