I have created revel test suite, I use Assertf for checking an error.
t.Assertf(err == nil, "error occurred: %v", err)
It worked without any problem in my Windows and also Mac OSX. But in my remote server, Ubuntu 16.04, whenever assert error, I got error message like this.
server.go:2753: http: panic serving [::1]:44626: open /go/src/runtime/debug/stack.go: no such file or directory

This is due to a bug in revel - https://github.com/revel/revel/issues/1287
The issue is that your server has GOPATH set equal to /go, and revel incorrectly identifies the first frame of the stacktrace (/usr/local/go/src/runtime/debug/stack.go:24) as being in the GOPATH because it contains /go/src. You can work around the issue by manually setting/maintaining a different GOPATH on your server that doesn't contain /go in the path anywhere. This is also an issue with the official docker containers for go found at https://hub.docker.com/_/golang/
