I have a small test directory that contained // +build !js in the single package file as well as the single test file. This causes gopherjs to complain:

no buildable Go source files in /home/jonhall/src/kivik/kivik/x/kivikd/test

This seems to match the behavior of go test if called with a single path, but when go test ./... is called, any directories that contain no buildable source are just silently skipped. I think gohperjs should probably do the same.
