How to pass a struct to another package?

How to pass a struct to another package?

This is a very watered down version of what I'm trying to do but please
help me with the following scenario:
PackageA.go
package A
import "B"
type TestStruct struct {
Atest string
}
func Test() {
test := TestStruct{"Hello World"}
B.Test(test)
}
PackageB.go
package B
import "fmt"
func Test(test TestStruct) {
fmt.Println(test.Atest)
}
This fails with undefined: test when it hits Package B
Basically I'm having issues passing structs from one package to another or
even passing variables that act as pointers to other structs or functions.
Any pointers would be very helpful.
