These don't belong to VM as they compile some Go code and run it in a VM. One may call them integration tests, but I prefer to attribute them to compiler. Moving these tests into pkg/compiler also allows to properly count the compiler coverage they add: -ok github.com/CityOfZion/neo-go/pkg/compiler (cached) coverage: 69.7% of statements +ok github.com/CityOfZion/neo-go/pkg/compiler (cached) coverage: 84.2% of statements This change also fixes `contant` typo and removes fake packages exposed to the public by moving foo/bar/foobar into the testdata directory.
