为Salesforce/APEX触发器编写测试类

Question

我已在Salesforce APEX中记录了触发器。它工作正常。

触发器代码为：

trigger SDRDemoUpdate_test on Event (before update) {
    Map<ID,Event> records = New Map<ID,Event>([SELECT CreatedBy.Name FROM Event WHERE ID IN: trigger.new]);

    for (Event obj :Trigger.new){
        obj.SDR_Original_Demo__c = records.get(obj.id).CreatedBy.Name;
    }
}

现在我正在尝试为它的测试类编写代码。它在线上给出错误，说对象无法解析为字符串。

测试等级代码为：

@isTest
public class originalDemo {
    static testMethod void test_original_demo() {
        Event obj = new Event();
        obj.CreatedBy = 'Tom';
        obj.Owner = 'Jack';
        obj.What = 'Opportunity';

        insert.obj;

        userInfo.getName();
    }
}

期待找到解决方案。任何帮助都将不胜感激。

谢谢

你在这一行的问题

    obj.CreatedBy = 'Tom';
    obj.Owner = 'Jack';
    obj.What = 'Opportunity';

您试图将字符串传递给需要Id的字段。

    User user = [SELECT Id FROM User LIMIT 1];
    obj.CreatedById = UserInfo.getUserId();
    obj.OwnerId = user.Id;
    obj.WhatId = opportunity.Id;
