golang test for sub directories fails

Question

In my use case I am setting up a single go test which runs all _test.go in all packages in the project folder. I tried to achieve this using $go test ./... from the src folder of the project

 /project-name
       /src
          /mypack
             /dao
             /util

When I try to run the test it is asking to install the packages which are used in the imported packages. For example if I import "github.com/go-sql-driver/mysql", it might have used another package github.com/golang/protobuf/proto. I did not manually import the proto package. The application runs without manually importing the inner package. But when I run the tests it fails. But individual package test succeeded. Do I have to install all the packages in the $go test ./... error manually?

Could anyone help me on this?

You need to run go get -t ./... first to get all test deps.

From the go test -h :

The -t flag instructs get to also download the packages required to build the tests for the specified packages.
