Hi! I am working on a package SGP where I am trying to export the in-struct functions but still getting the error:

sgp = SGP() # Create an instance of the SGP clas  
ERROR: UndefVarError: `SGP` not defined  
Stacktrace:  
[1] top-level scope  
@ c:\Users\mridu.julia\dev\SparseGaussianProcess\test\runtests.jl:5

Here is my SparseGaussianProcess.jl file code:  
module SparseGaussianProcess

export SGP  
abstract type AbstractSurrogateModel end  
mutable struct SGP \<: AbsractSurrogateModel  
# Member declarations and functions#  
end

And this is the runtests.jl file I have:  
using Test  
using SparseGaussianProcess # Import the module  
using Random

sgp = SGP() # Create an instance of the SGP clas  
@testset “SparseGaussianProcess.jl” begin

Perhaps a typo?
