触发帐户上的自动活动创建（更新后）
{
列表任务=新建列表（）；
for（整数i=0；i

触发器用于“更新后”，但我在测试代码中看到的只是“插入测试任务”

您需要修改触发器以包含“after insert”，或者调整测试，以便它也对对象“testTask”进行更新。一旦您执行了这两个选项中的任何一个，就会从测试代码中调用触发器代码

Trigger  AutoActivityCreation on Account(after update)
{

    List<Task> task = new List<Task>();

for (Integer i = 0; i < Trigger.new.size(); i++) {

                       List<String> techs = Trigger.new[i].Toolsberry_new_tech_installs__c.split(';');                    
                       Integer added_tech = techs.size();

                       if(Trigger.new[i].Toolsberry_new_tech_installs__c=='null'){
                           added_tech=0;
                       }

                        List<String> re_techs = Trigger.new[i].Toolsberry_removed_tech_installs__c.split(';');
                       Integer removed_tech = re_techs.size();

                        if(Trigger.new[i].Toolsberry_removed_tech_installs__c=='null'){
                           removed_tech=0;
                       }


task.add(new Task(
