这是一个Apex测试类代码，我在这里得到的是，这个类将包含硬编码值来创建并提交票证以供审批。
我想知道我是否能在这里得到任何指导，因为我真的不能从其他地方得到。感谢您提供的任何帮助。
PS。这是Salesforce平台-Remedyforce相关。

问题似乎出现在generateAndSubmitObject（）静态方法中。有很多奇怪的行为。
我要把它一行一行地分解。
第1行：testIS获取一个新实例化的BMCServiceDesk__Change_Request__c对象。
第2行：testIS获取名称等于"CR00002135"的BMCServiceDesk__Change_Request__c对象的列表（但只有ID字段）。这里有两个问题。首先，这个动作使1号线完全无用。第二，这不会返回任何结果。您没有任何名为CR00002135的CR，这是您目前的数据库。
第3行：您正在将此空列表重新插入数据库。这又是一次无操作。
如果修复了第1-3行，那么剩下的部分应该可以工作。我的建议是，去掉第2行并更新第1行，这样当您实例化BMCServiceDesk__Change_Request__c对象时，它就可以获得您想要的所有信息。
