在Salesforce中的触发器上编写测试类

Question

I am a complete code noob and need help writing a test class for a trigger in Salesforce. Any help would be greatly appreciated.

Here is the trigger:

trigger UpdateWonAccounts on Opportunity(before Update) {
  Set < Id > accountIds = new Set < Id > ();

  //Collect End user Ids which has won Opportunities
  for (Opportunity o : Trigger.new) {
    if (o.isWon && o.EndUserAccountName__c != null) {
      accountIds.add(o.EndUserAccountName__c);
    }
  }

  List < Account > lstAccount = new List < Account > ();

  //Iterate and collect all the end user records
  for (Account a : [Select Id, Status__c From Account where Id IN : accountIds]) {
    lstAccount.add(new Account(Id = a.Id, Status__c = true));
  }

  //If there are any accounts then update the records
  if (!lstAccount.isEmpty()) {
    update lstAccount;
  }
}

Read An Introduction to Apex Code Test Methods and How To Write A Trigger Test .

Basically, you want to create a new testmethod that updates (inserts, deletes, undeletes, etc. depending on your trigger conditions) a record or sObject.

It looks somewhat like this:

public class myClass {
    static testMethod void myTest() {
       // Add test method logic to insert and update a new Opportunity here
    }
}
