go build works but go test does not

Question

Below is my project structure:

/user/home/go/src/github.com/my_go_proj
                                       /main.go
                                       /mypackage
                                                 /service.go
                                                 /service_test.go

GOPATH points to /user/home/go
cd /user/home/go/src/github.com/my_go_proj
go build ---> This works and creates the `my_go_proj` executable.
go test
?       github.com/my_go_proj   [no test files]
go test github.com/my_go_proj/mypackage
go build gopkg.in/tomb.v2: no buildable Go source files in 
FAIL    github.com/my_go_proj/mypackage [build failed]

go test ./...
?       github.com/my_go_proj   [no test files]
go build gopkg.in/tomb.v2: no buildable Go source files in 
FAIL    github.com/my_go_proj/mypackage [build failed]

How do I run go test to run the service_test.go test inside mypackage?

Update: updated the behaviour for go test ./...

does `go test ./...` work? (and what does `go build gopkg.in/tomb.v2` have to do with this?) — JimB, Dec 04 '15 at 16:57
Potential duplicate of [How to `go test` all testings in my project?](http://stackoverflow.com/questions/16353016/) and [Golang tests in sub-directory](http://stackoverflow.com/questions/19200235/). — Matthew Rankin, Dec 04 '15 at 17:06
I have no idea where gopkg.in/tomb.v2 is coming from. `go test ./...` also did not work. — suman j, Dec 04 '15 at 17:49
Something is trying to build "gopkg.in/tomb.v2", have you tried getting that dependency? — JimB, Dec 04 '15 at 17:58

To test all subdirectories use:

$ go test ./...

From the Relative import paths section of the Command go documentation:

Relative patterns are also allowed, like go test ./... to test all subdirectories. See 'go help packages' for details on the pattern syntax.

The problem was with the directory structure. My project source should be in $GOPATH. But it was inside $GOPATH/src.

Incorrect /user/home/go/src/github.com/my_go_proj
Correct /user/home/go/github.com/my_go_proj
