go test,can't find package

1,My gopath like this
>echo $GOPATH
/home/my/gopath,/home/my/IdeaProjects/XServer/src

2,and I have a project with directory structure like this:
/home/my/IdeaProjects/XServer
└── src
    ├── base
    │   ├── http
    │   ├── impl
    │   └── logger
    ├── comment
    │   ├── create(a test file under this directory)
    │   ├── delete
    │   ├── retrieve
    │   └── update
    ├── db
    ├── helper
    ├── util
    └── valid

3,and a test file dao_test.go is under /home/my/IdeaProjects/XServer/src/comment/create

4,and when I run: go test in directory /home/my/IdeaProjects/XServer/src/comment/create,got these errors:
