测试类在顶点

Question

所以我是 salesforce 的新手，我完成了培训，现在我正在做一个项目。但是在我的项目中，我偶然发现了一个测试类，我没有找到编写它的方法，所以如果有人能帮助我找到一种编写它的方法，我将不胜感激。这是代码：

public class AP01_Opportunity 
{
//Method to create a new service contract when opportunity = Gagné
public static void CreateContract(List<Opportunity> listOpp, Map<Id, Opportunity> oldMap)
{
//Variable Declaration
ServiceContract sc;
List<ServiceContract> listSCToAdd = new List<ServiceContract>();
List<ContractLineItem> listContractItems = new List<ContractLineItem>();
List<Opportunity> listOppGagne = new list<Opportunity>();
//Loop in list of opportunities
for(Opportunity opp : listOpp)
{
if(opp.StageName == Label.ClotureGagne && !oldMap.get(opp.Id).isWon)
{
listOppGagne.add(opp);
}
}
//check if list has opportunity becoming won
if(listOppGagne.size()  > 0){
Map<Id, Opportunity> mapOppGagne = new Map<Id, Opportunity> ([SELECT Id,
    Name,
    StageName,
    Pricebook2Id,
    Account.Name, 
    (SELECT Id,
     PricebookEntryId,
     PricebookEntry.Name, 
     Quantity, 
     UnitPrice 
     FROM OpportunityLineItems)
    FROM Opportunity
    WHERE Id in :listOppGagne]);
for( Opportunity opp : listOppGagne )
{
//Create new service contract
sc = new ServiceContract();
sc.Name = opp.Name;
sc.ApprovalStatus = Label.Activated;
sc.OpportunityId__c = Id.valueOf(opp.Id);
sc.Pricebook2Id = opp.Pricebook2Id;
sc.StartDate = Date.today();
listSCToAdd.add(sc);
}
if(listSCToAdd.size() > 0){
insert listSCToAdd;
Opportunity currentOpp;
ContractLineItem cli;
Id oppId;
for(ServiceContract servcont : listSCToAdd)
{
oppId = servcont.OpportunityId__c;
if(mapOppGagne.containsKey(oppId))
{
currentOpp = mapOppGagne.get(oppId);
//copy the oppLineItems per opportunity to the respective Service Contract
for(OpportunityLineItem items : currentOpp.OpportunityLineItems)
{
cli = new ContractLineItem();
cli.PricebookEntryId = items.PricebookEntryId;
cli.Quantity = items.Quantity;
cli.UnitPrice = items.UnitPrice;
cli.ServiceContractId = servcont.Id;
listContractItems.add(cli);
}
}
}
if(listContractItems.size() > 0)
{
insert listContractItems; 
}
}

}
}
}

当商机阶段更改为"Cloturé Gagné"(法语中表示已关闭(时，此代码是一个触发器，用于创建新的服务合同记录，其中包含从商机行项复制的合同明细项。

提前谢谢你。

为了编写一个简单的测试类，我建议您使用以下指南： https://developer.salesforce.com/docs/atlas.en-us.apexcode.meta/apexcode/apex_qs_test.htm

这个想法很简单：假设您在测试类中创建了一个机会，并在您的案例中进行插入或更新 - 您的触发器类将自动触发并运行AP01_Opportunity类中的代码。你可以放一些

System.debug('some message');

检查逻辑是否按预期工作以及执行了哪些代码块
