Hi all,

I'm struggling to get code coverage on my class.  I've never written a test class for a Controller, only triggers, so I'm a bit lost.
Any help would be greatly appreciated.
 

Thanks,

Greg

Class

public with sharing class ShowAttachments_Controller {
private List<Id> photoIds;
private ApexPages.standardController controller;
private List<Id> chatterphotoIds;
private Acquisition_Report__c acquisition;
public ShowAttachments_Controller(ApexPages.StandardController controller) { 
this.controller = controller;         
 this.acquisition = (Acquisition_Report__c)controller.getRecord();
}

public List<Id> photosfromchatter {
get {
if(chatterphotoIds == null) {
chatterphotoIds = new List<Id>();
for(ContentVersion cnt : [select Id from ContentVersion ]) {
chatterphotoIds.Add(cnt.Id);
}
}

return chatterphotoIds;
}
} 

public List<Id> photos {
        get {
            if(photoIds == null) {
                photoIds = new List<Id>();
                for(Attachment att : [select Id from Attachment where ParentId = :acquisition.Id]) {
                    photoIds.Add(att.Id);
                }
            }
                             
            return photoIds;
        }
    }
     
    public Integer totalPhotos {
        get {
            return photos.size();
        }
    }

}
