How do I test a trigger with an approval process? - triggers

Question

I have a trigger which initiates an approval process when certain criteria are met:
trigger AddendumAfterIHMS on Addendum__c (after update) {
for (integer i = 0; i<Trigger.new.size(); i++){
if(Trigger.new[i].RecordTypeId != '012V0000000CkQA'){
if(Trigger.new[i].From_IHMS__c != null && Trigger.old[i].From_IHMS__c == null){
ID addendumId = Trigger.new[i].Id;
// Start next approval process
Approval.ProcessSubmitRequest request = new Approval.ProcessSubmitRequest();
request.setObjectId(addendumId);
Approval.ProcessResult requestResult = Approval.process(request);
}
}
}
}
It works perfectly, but now i need to create a test class for it. I have created a class which brings the code up to 75% coverage, which is the minimum, but I'm picky and like to have 100% coverage on my code. The test class I have now gets stuck on the line request.setObjectId(addendumId); and doesn't move past it. The error I receive is:
System.DmlException: Update failed. First exception on row 0 with id a0CV0000000B8cgMAC; first error: CANNOT_INSERT_UPDATE_ACTIVATE_ENTITY, AddendumAfterIHMS: execution of AfterUpdate
Here is the test class that I have written so far, most of the class actually tests some other triggers, but the important line which is throwing the error is the very last line update addendumTierFeature;
#isTest
private class AddendumTest {
static testMethod void myUnitTest() {
// Query Testing Account, will need ID changed before testing to place into production
Account existingAccount = [SELECT Id FROM Account LIMIT 1];
Model__c existingModel = [SELECT Id FROM Model__c WHERE Active__c = TRUE LIMIT 1];
Pricebook2 existingPricebook = [SELECT Id,Name FROM Pricebook2 WHERE IsActive = TRUE LIMIT 1];
List<Contact> existingContacts = [SELECT Id,Name FROM Contact LIMIT 2];
Contact existingContactPrimary = existingContacts[0];
Contact existingContactSecondary = existingContacts[1];
Opportunity newOpportunity = new Opportunity(
Name = 'New Opportunity',
Account = existingAccount,
CloseDate = Date.today(),
Order_Proposed__c = Date.today(),
StageName = 'Branch Visit - Not Responding',
Opportunity_Follow_Up__c = 'Every 120 Days',
LeadSource = 'Farm Lists',
Source_Detail__c = 'FSBO',
Model_Name__c = existingModel.Id,
Processing_Fee__c = 100.50,
Site_State__c = 'OR',
base_Build_Zone__c = 'OR',
Pricebook_from_Lead__c = existingPricebook.Name
);
insert newOpportunity;
//system.assert(newOpportunity.Id != null);
ID newOppId = newOpportunity.Id;
OpportunityContactRole contactPrimary = new OpportunityContactRole(
Role = 'Primary',
IsPrimary = true,
OpportunityId = newOppId,
ContactId = existingContactPrimary.Id
);
OpportunityContactRole contactSecondary = new OpportunityContactRole(
Role = 'Primary',
IsPrimary = false,
OpportunityId = newOppId,
ContactId = existingContactPrimary.Id
);
insert contactPrimary;
insert contactSecondary;
newOpportunity.Name = 'Different - Updating';
newOpportunity.Order_Accepted__c = Datetime.now();
update newOpportunity;
Addendum__c addendumCustomOption = new Addendum__c(
RecordTypeId = '012V0000000CkQA', //Pre Priced Custom Option
Opportunity__c = newOppId,
Item_Pre_Priced_Description__c = 'a1eV00000004DNu',
Reason__c = 'This is a reason',
Item__c = 'This is an Item',
Quantity__c = 1
);
Addendum__c addendumTierFeature = new Addendum__c(
RecordTypeId = '012V0000000Cjks', //Tier Feature
Opportunity__c = newOppId,
Category__c = 'Countertops',
Reason__c = 'This is a reason',
Item__c = 'This is an Item',
Quantity__c = 1
);
insert addendumCustomOption;
insert addendumTierFeature;
addendumCustomOption.Quantity__c = 2;
addendumTierFeature.Quantity__c = 2;
update addendumCustomOption;
update addendumTierFeature;
update newOpportunity;
addendumTierFeature.To_IHMS__c = system.now();
update addendumTierFeature;
addendumTierFeature.From_IHMS__c = system.now();
update addendumTierFeature;
}
}
Any help on this matter would be greatly appreciated. I believe the problem is in the way I am testing the approval process start. Is there by chance a special testing function for this?

Answer 1

After fiddling around for a little while I discovered that the error was actually tied into my approval process. I kept digging into the error logs until I got to the error: caused by: System.DmlException: Process failed. First exception on row 0; first error: MANAGER_NOT_DEFINED, Manager undefined.: []. This phrase indicates that there is no one defined for the next step in my approval process.
When I created the opportunity, I did not set the owner and somehow this created an opportunity which had an owner without a manager. The addendum was also created without an owner/manager. So when I tried to launch the next approval process, there was no manager to send the approval to and an error was thrown.
