how to remove code duplicacy while using separate sets in safetestsets

I'm new to Julia and I'm trying to write tests for Genie. I'm using SafeTestsets. It can really help us separate test in different sets but now there is a lot of duplicate code because you can't access outside set's scope

For example in below example, using Genie, Genie.Assets are repeating

@safetestset "Assets functionality" begin

  @safetestset "Assets paths" begin
    using Genie, Genie.Assets

    @test include_asset(:css, "foo")  == "/css/foo.css"
    @test include_asset(:js, "foo")   == "/js/foo.js"

    @test css_asset("foo") == css("foo") == "/css/foo.css"
    @test js_asset("foo") == js("foo") == "/js/foo.js"
  end;

  @safetestset "Expose settings" begin
    using Genie, Genie.Assets

    @test js_settings() == "window.Genie = {};\nGenie.Settings = {\"webchannels_autosubscribe\":true,\"server_host\":\"127.0.0.1\",\"webchannels_subscribe_channel\":\"subscribe\",\"server_port\":8000,\"webchannels_default_route\":\"__\",\"webchannels_unsubscribe_channel\":\"unsubscribe\",\"websockets_port\":8001}\n"
  end

  @safetestset "Embedded assets" begin
    using Genie, Genie.Assets

    @test channels()[1:18] == "window.Genie = {};"
    @test channels_script()[1:27] == "<script>\nwindow.Genie = {};"

    @test channels_support() == "<script src=\"/__/channels.js?v=$(Genie.Configuration.GENIE_VERSION)\"></script>"
    @test Genie.Router.routes()[1].path == "/__/channels.js"
    @test Genie.Router.channels()[1].path == "/__/unsubscribe"
    @test Genie.Router.channels()[2].path == "/__/subscribe"

    @test favicon_support() == "<link rel=\"icon\" type=\"image/x-icon\" href=\"/favicon.ico\" />"
  end

end;
