GoConvey
Go testing in the browser, integrates with `go test`
... the browser real tight if you need to put it beside your code. The web UI supports traditional Go tests, so use it even if you're not using GoConvey tests. Since GoConvey integrates with go test, you can keep running tests in the terminal or use the auto-updating web UI for test results. Though writing tests with Convey() and So() is optional, it's more expressive than t.Errorf().
