I had the same question. I fixed it with a Unittest. Indeed you need to stub out the TraceWriter and the TimerInfo.

Here some code how I did this.

TimerInfo:

public class ScheduleStub : TimerInfo
{
    public ScheduleStub(TimerSchedule schedule, ScheduleStatus status, bool isPastDue = false) : base(schedule, status, isPastDue)
    {
    }
}

And the TraceWriter:

 public class TraceWriterStub : TraceWriter
{
    protected TraceLevel _level;
    protected List _traces;

    public TraceWriterStub(TraceLevel level) : base(level)
    {
        _level = level;
        _traces = new List();
    }

    public override void Trace(TraceEvent traceEvent)
    {
        _traces.Add(traceEvent);
    }

    public List Traces => _traces;
}
