我不能让这个 JUnit 测试通过我的生活。有人可以指出哪里出了问题。我正在进行数据迁移（MSSQL SERVER 2005），但我的 sourceDBUrl 和 targetDCUrl 具有相同的 URL，以便将其缩小到语法错误。这就是我所拥有的，一个语法错误。我正在比较查询表的结果
SELECT programmeapproval, resourceapproval FROM tr_timesheet WHERE timesheetid = ?
并且测试总是失败，但通过了我开发的其他junit测试。我创建了 3 个不同的 resultSetsEqual 方法，但没有一个工作。然而，我开发的其他一些 JUnit 测试已经通过。查询：
从 tr_timesheet 中选择 timesheetid、programapproval、resourceapproval
返回三列
- timesheetid (PK,int, not null) (填充数字 2240 - 2282)
- programapproval (smallint,not null) （在每个字段中填充数字 1）
- resourceapproval （smallint，not null）（在每个字段中填充数字 1）
当我运行嵌入在代码中的查询时，它只返回一行，其中包含 programapproval 和 resourceapproval 列，并且两个字段都填充了数字 1。
我已正确安装并测试了所有 jdbc 驱动程序的连接性。根据 IDE，此时 JUnit 测试失败。
assertTrue(helper.resultSetsEqual2(sourceVal,targetVal));
这是代码：
