            // setup
            stubConsoleFn(fnName);
            const spiedFn = console[fnName] as Sinon.SinonSpy;

            const log = new Log({enabled: false, level: "all"});

            // exercise (1)
            log.setEnabled(dEnabled1.promise)
            log[fnName]("1");
            log.setEnabled(dEnabled2.promise)
            log[fnName]("2");
            log.setEnabled(dEnabled3.promise)
            log[fnName]("3");

            // verify (1)
