如何使用审批流测试触发器？

Question

我有一个触发器，它在满足某些条件时启动审批流程：

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);

        }
    }
  }
}

它工作得很好，但现在我需要为它创建一个测试类。我创建了一个类，它将代码的覆盖率提高到75%，这是最低要求，但我很挑剔，喜欢在我的代码上有100%的覆盖率。我的测试类现在被request.setObjectId(addendumId);这行卡住了，并且没有通过它。我收到的错误是：

System.DmlException: Update failed. First exception on row 0 with id a0CV0000000B8cgMAC; first error: CANNOT_INSERT_UPDATE_ACTIVATE_ENTITY, AddendumAfterIHMS: execution of AfterUpdate

这是我到目前为止编写的测试类，该类的大部分实际上测试了其他一些触发器，但抛出错误的重要行是最后一行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;

  }
}

在这件事上的任何帮助都将非常感谢。我认为问题出在我测试审批流程启动的方式上。有没有专门的测试函数呢？

Answer 1

在闲逛了一小段时间后，我发现这个错误实际上与我的审批流程有关。我一直深入研究错误日志，直到找到错误：caused by: System.DmlException: Process failed. First exception on row 0; first error: MANAGER_NOT_DEFINED, Manager undefined.: []。此短语表示没有为我的审批流程中的下一步定义任何人。

当我创建opportunity时，我没有设置所有者，不知何故，这创建了一个拥有所有者但没有经理的opportunity。附录也是在没有所有者/经理的情况下创建的。因此，当我尝试启动下一个审批流程时，没有经理可以向其发送审批，因此抛出了一个错误。
