Can't export items from @testmodule modules

It would be very useful to export items from a @testmodule, but that appears not to be possible right now, correct?

I have the following in a file called test/test_test.jl:

@testmodule TestHelpers begin
    f(x, y) = x + y
    export f
end

@testitem "Test the tests" setup = [TestHelpers] begin
    # Try the exported function
    try
        f(1, 2) == 3
    catch e
        println("Error f(1, 2): ", e)
    end

    # Manually export it
    f = TestHelpers.f
    @test f(1, 2) == 3
end

When I run that from the VS Code testing pane, I get this output:

Error f(1, 2): UndefVarError(:f)
Test Summary:                        | Pass  Total  Time
.../test/test_test.jl:Test the tests |    1      1  0.0s

Is there some other technique besides this hacky workaround that I might have missed?

I'm using TestItemRunner v1.0.5 and VS Code 1.95.1. Thanks.

Yes, agreed.

At the moment the modules that are listed in the setup section are imported into the test item module, but I think we should change that to using instead, and then your scenario should work.

Technically that is a breaking change, but given how new all of this is I think we can just do that.

Yeah, that sounds good to me. After all, for a @testmodule, if someone doesn't want stuff exported, they can just not export it. Thanks.
