There are several automatic test runners in Go which work from the terminal. Here's one for example: https://github.com/levicook/glitch. Not as pretty, but perhaps more useful if you want to avoid the browser.
You're right; and that's cool, I haven't seen that one before. These auto-testers kind of helped inspire the idea (we just wanted more useful output without going to the terminal).
Keep in mind, too, that GoConvey can automatically without the browser by using an idle.py script that's bundled in. If that's all you need, though, then something more lightweight like glitch looks good.
