去lang测试结构-使用银杏花测试时间太长

I am new to go lang, and i have a question regarding the structure of the project. let says i have a the following project structure.

myproject
  package1
     mycode.go
     mycode_test.go
  package2
     morecode.go
     morecode_test.go

each one of the *_test.go has the following code:

    func TestMyCode(t *testing.T) {
         RegisterFailHandler(Fail)
         RunSpecs(t, "MyCode Test Suite")
}

    var _ = BeforeSuite(func() {
        //some inits
    }

And when i run the test with ginkgo -r, all is fine and the tests are running fast.

Now due to some cyclic dependencies i had to restructure the project. I created another package called tests and move the *_test.go files there. And created one initialization file called init_test.go which has the following code:

  func TestInit(t *testing.T) {
         RegisterFailHandler(Fail)
         RunSpecs(t, "init Test Suite")
}

    var _ = BeforeSuite(func() {
        //some inits
    }

so the new structure is something like that

myproject
      package1
         mycode.go
      package2
         morecode.go 
      tests
        init_test.go
        mycode_test.go
        morecode_test.go

The cyclic dependencies issue was solved, but the problem now is that the tests take much more longer to run several minutes instead of several seconds, and i don't know why. What have i done wrong?
