When I first checked out GoConvey, the project I was working on at the time had tests that took upwards of 30s to complete, which resulted in an incredibly frustrating experience.
Ultimately I just stopped using it, and wrote off GoConvey as a cool, but mostly unnecessary tool.
I eventually got around to sorting out my tests (which now run in under 3s!) so I thought I'd give GoConvey another try, and I have to admit it's pretty sweet.
I still feel like it's overkill, but it definitely makes for a pleasant local CI experience (Especially with the Pass/Fail Desktop alerts).
