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：

/ *这是一个JUNIT类****？

public void testQUERY_CHECKALERT() throws Exception{


UnitTestHelper helper = new UnitTestHelper();
Connection con = helper.getConnection(helper.sourceDBUrl);
Connection conTarget = helper.getConnection(helper.targetDBUrl);

PreparedStatement stmt = con.prepareStatement("select programmeapproval, resourceapproval from tr_timesheet where timesheetid = ?");
stmt.setInt(1, 2240);
ResultSet sourceVal = stmt.executeQuery();

stmt = conTarget.prepareStatement("select programmeapproval, resourceapproval from tr_timesheet where timesheetid = ?");
stmt.setInt(1,2240);
ResultSet targetVal = stmt.executeQuery();
assertTrue(helper.resultSetsEqual2(sourceVal,targetVal));
}}

false当物体equal彼此接近时，你回来了。在这种方法中，我将条件更改为not equals.

public boolean resultSetsEqual2 (ResultSet source, ResultSet target) throws SQLException{
    while(source.next())
    {
        target.next();
        ResultSetMetaData metadata = source.getMetaData();
        int count = metadata.getColumnCount();
        for (int i =1; i<=count; i++)
        {
             if(!source.getObject(i).equals(target.getObject(i))) //added !
             {
                  return false;
             }
        }
    }
    return true;
}
