Subsonic 如何模拟亚音速执行器方法？

我有一个调用存储过程并在执行DataReader后返回数据的方法。 我试图用mock测试这个方法。我不知道如何返回值

有人这样做吗？感谢您的回复

这是我的密码：

以下是测试方法：

如果您想创建具有特定形状和大小的DataReader，那么我建议您查看DataTable.CreateDataReader。然后，您可以在示例中设置ExecuteReader以返回此数据读取器。

以下链接帮助我。。。

我使用MockDbDataReader方法来模拟数据

        public void Can_get_completedBatches_return_single_batch()
        {
            var date = DateTime.Now;
            var file = new File() { FileID = 202, DepositDate = DateTime.Now };
            var batch1 = new Batch() { FileID = 202, BatchID = 1767, LockboxNumber = "1", IsLocked = true, LockedBy = "testUser" };
            var transaction1 = new Transaction() { BatchID = 1767, TransactionID = 63423, CheckAmount = 100.0 };
            var distribution1 = new Distribution() { TransactionID = 63423, InvoiceNumber = "001", Amount = 100.0, DateCreated = date, DateModified = date, TransType = 2 };

            repo.Add<File>(file);
            repo.Add<Batch>(batch1);

            CompletedBatches completedBatches = new CompletedBatches(provider.Object);

            provider.Setup(x => x.ExecuteReader(It.IsAny<QueryCommand>())).Returns(MockDbDataReader());

            var completedBatchesList = completedBatches.GetCompletedBatchList(202);
            Assert.AreEqual(1, completedBatchesList.Count());

        }


// You should pass here a list of test items, their data
    // will be returned by IDataReader
