Please help me, I can't see any reference on how to make test class for it..

public class ProcessController {
    public ProcessController(ApexPages.StandardSetController stdController) {}
    public PageReference runBatch() {
        MyUpdateBatch batch = new MyUpdateBatch ();
        Database.executeBatch(batch);
        
        return new ApexPages.Action('{!List}').invoke();
    }
}

Hi! I am trying to upload an Atttachments based on the selection and criteria from Lightning Component that will be saved to Custom Setting.

For example, the criteria is Opportunity - Stage - Closed Won, I need to query to get all attachments from Closed Won Opportunity and upload them to AWS.

I'm doing an upload attachment to AWS, but I'm getting this error -- 'You have uncommitted work pending. Please commit or rollback before calling out'
How do I fix this?

So, I have a Lightning Component, when changes occurs there, it will save on Custom Settings.

If Object__c = Opportunity and Value__c = Closed Won from CustomSettings, I have to find the Opportunity record that meets the condition. If the Opporutnity record has Notes and Attachments, it will be uploaded to AWS.

Should I do it on Controller class or another trigger or class?

        Set<String> csObjNames = new Set<String>();
        Map<String, String> mapName = new Map<String, String>();
