Does anybody know whether I can have a struct within an Interface and then build a getter for it?

So assuming I have 2 files:

File 1:

contract A{
struct Test{}
getTestById() -> return Test test
}

File 2:

interface IConA{
struct Test{}
getTestByID() external …
}

contract B {
//create an object of Type Test that pulls data from contract A via getTestByID()
}
