[SalesForce] Ghost Schedulable Classes Blocking Deployment

What about passing parameters through constructor and storing them in instance variables?

public class Dummy_Schedulable_Class implements Schedulable{

    public List<String> names;
    public List<String> cronExpressions;

    public void execute(SchedulableContext SC) {
        System.debug(LoggingLevel.ERROR, names );
        System.debug(LoggingLevel.ERROR, cronExpressions );
        testScheduleClassMethod(names[0]);
    }

    public void testScheduleClassMethod(string argPass){

    }

    public Dummy_Schedulable_Class ( List<String> aNames, List<String> aCronExps) {
        if ( names == null ) {
            names = aNames;
        } else {
            names.addAll(aNames);
        }
        if ( cronExpressions == null ) {
            cronExpressions = aCronExps;
        } else {
            cronExpressions.addAll(aCronExps);
        }
    }

}

And whenever you need to pass parameters you can do the following:

System.schedule('test', '0 47 18 * * ?', new Dummy_Schedulable_Class(new String[]{'a','b'}, new String[]{'c','d'}));

Fairly certain you'll need to change your approach. Fortunately this can be a quick refactor. Just extract your constructor into a method that takes the id param, then create a second constructor that also takes and id param, and wire it all up. You'll then be able to call it from your batch class without having to deal with re-testing the visualforce controller you tweaked.

Initial Constructor

public class MyController {
    private Id myId;

    public MyController() {
        myId = ApexPages.getCurrentPage().getParameters().get('id');
        ... stuff you don't want to touch ...
    }
}

Refactored

public MyController {
    private Id myId;

    public MyController() {
        init(ApexPages.getCurrentPage().getParameters());
    }

    public MyController(Id fromTestId) {
        init(fromTestId);
    }

    private void init(Id inputId) {
        myId = inputId;
        ... stuff you don't want to touch ...
    }
}
