There seems to be nothing in the Apex guides on how to test a set controller. This method runs when a button is clicked on a custom object list view and processes the records selected from the list view.
How do I test it? I can't figure out how to get any records "selected" in the StandardSetController.
public with sharing class replacerRunAllSelectedRulesController{
ApexPages.StandardSetController setCon;
private PageReference savePage;
public replacerRunAllSelectedRulesController(ApexPages.StandardController controller) {
//Not sure why this is needed...
}//replacerRunAllSelectedRulesController
public replacerRunAllSelectedRulesController(ApexPages.StandardSetController controller) {
setCon=controller;
List<Replacer__c> selectedRules=new List<Replacer__c>();
}//replacerRunAllSelectedRulesController
public PageReference runSelectedRules(){
List<Replacer__c> selectedRules=new List<Replacer__c>();
for(sObject s: setCon.getSelected()){
Replacer__c r=(Replacer__c)s;
selectedRules.add(r);
}//for 1
String objectName='';
Boolean sendEmail=TRUE;
if(selectedRules.size()==0){
ApexPages.addmessage(new ApexPages.message(ApexPages.severity.ERROR,
'You must select at least one rule. Please go back and select a rule by checking the checkbox and try again.'));
}else{
Integer numJobsCantBeRunNow=replacerExecute.replacerQueueBatchJobs(objectName, selectedRules, sendEmail);
if(numJobsCantBeRunNow==0){
ApexPages.Message myMsg = new ApexPages.Message(ApexPages.Severity.CONFIRM,'Replacement has begun. This can take ~10-30 minutes for each 10,000 records. You will receive 1 email confirmation for each different object as all rules for one object are run together in one job.');
ApexPages.addMessage(myMsg);
}else{
//else throw an error that they need to select fewer rules to run right now
ApexPages.addmessage(new ApexPages.message(ApexPages.severity.ERROR, 'The selected rules cannot be run now as they would exceed your companies batch job limit of 5. One job is created for each different object. Please unselect ' + numJobsCantBeRunNow + ' object\'s rules and try again. To view the batch queue, click Setup-->Monitoring-->Apex Jobs'));
}//if 2
}//if 1
return ApexPages.CurrentPage();
}//runSelectedRules
}//replacerRunAllSelectedRulesController
Here's where I'm at - I have the controller assigned, but can't figure out how to select the records in the set controller:

insert rules;

ApexPages.StandardSetController sc = new ApexPages.StandardSetController(rules);
replacerRunAllSelectedRulesController scExt = new replacerRunAllSelectedRulesController(sc);
//How do I select both "rules"?

Nothing changed with my test - it only calls one batch job. This worked 2wks ago, but now is failing, preventing me from uploading an important bug fix to my customers.
22:56:34.835|EXCEPTION_THROWN|[EXTERNAL]|System.UnexpectedException: No more than one executeBatch can be called from within a testmethod. Please make sure the iterable returned from your start method matches the batch size, resulting in one executeBatch invocation.
My only change was an addition of a 3rd test that calls the same method "TryBatchJobsAgain", which passes, despite this one failing. Perhaps the test doesn't truly finish the batch job before the other test starts?
When I comment out this test, an unrelated test fails that calls a separate batch job.
When I move that test to a completely separate test class, it still fails.
