    describe('Test', ()=>{
        JasmineKarmaTypeScriptMocker('qs', { parse: ()=>()=>"result})
        it('it', ()=>{

        })
    })

    import { JasmineKarmaTypeScriptMockerSingle } from "karma-typescript-mock-jasmine";
    describe('Test', ()=>{
        JasmineKarmaTypeScriptMockerSingle('qs', parse',  ()=>()=>"result)
        it('it', ()=>{

        })
    })
