Moving the declaration into the given() block works. Did direct call rather than using DI/1.

testDI-works.cfc

component extends="testbox.system.BaseSpec" accessors="true"{
	function beforeAll(){
	}
	function run( testResults, testBox ){
		feature( "Get a Count of Responses", function() {
			describe("I want to know how many responses we have in the system"
				, function() {
				scenario( "Get all Response counts", function(){
					given( "I have a Survey ID",function() {
						variables.resultsService = new model.services.resultsService();
						when("I run the request the for the survey response count", function() {
							count = variables.resultsService.countResponses(1);
							then("then I should get a struct", function() {
									expect(count).toBeStruct();
							});
						});
					});
				});
			});
		});
	}
}
