Hi,

I have created a custom button on the Opportunity object.  When clicked it runs a class which in turn starts off the approval process. 

This works fine in my developer sandbox but is not deploying due to code coverage issues.  I wonder if anyone can help, bearing in mind I have got as far as I can with some research as I am not a programmer and wanting to learn

Thanks

Class code with no coverage: -

global class Opportunity_Approval_to_PrepBid {

        public String myopi {get; set;}
        Webservice static String callApproval(String myopi) {

        Opportunity op = new Opportunity(Id=myopi);
        update op;

                Approval.ProcessSubmitRequest req1 = new Approval.ProcessSubmitRequest();
                req1.setComments('Submitted for Approval');
                req1.setObjectId(myopi);
                Approval.ProcessResult res = Approval.Process(req1);   
                
                return null;
              
    }
}


Test class I tried: -

@IsTest

Public Class testApprovePrepare
 {
    static testMethod void testApprovePrepare()
    {
    
    Account a = new Account();
    a.Name ='demo';
    a.Industry = 'Education';
    a.BillingCountry = 'United Kingdom';
    insert a;
    
    Opportunity o = new Opportunity();
    o.AccountId = a.Id;
    o.StageName = 'Pipeline';
    o.Business_Unit__c = '1Spatial United Kingdom';
    o.Name = 'Test';
    o.Opportunity_Type__c = 'Contract Renewal';
    o.Contract_Type__c = 'Framework';
    o.Estimated_Value_Number__c = 10000;
    o.Opportunity_Submission_Date__c = Date.TODAY();
    o.CloseDate = Date.TODAY() +2;
    o.Probability__c = '80-99%';
    o.Purchase_Order__c = 'PO Pending';
    o.Solution_Summary__c = 'Hardware';
    o.Description = 'Renewal Contract for the next financial year';
    o.Opportunity_Process_Stage__c= 'Qualified Opportunity';
    insert o;
    
    Approval.ProcessSubmitRequest req1 = new Approval.ProcessSubmitRequest();
                req1.setComments('Submitted for Approval');
                req1.setObjectId(o.Id);
                req1.setProcessDefinitionNameOrId('Auto_Approval_to_Prepare_Bid');
                Approval.ProcessResult res = Approval.Process(req1); 
                
                try{
            res = Approval.process(req1);
        }catch(Exception e){
            System.debug('No approval process has been setup yet.');


     }
}
}

Any help would be appreciated in getting this deployed to production

Many Thanks
