Question

我正在使用伟大的Winterdom BizTalk测试库来测试将平面文件转换为15个记录。

部署到BizTalk时，接收管道工作正常。

这是我的单元测试：

[DeploymentItem(@"TestData\Maps\FromCarrier\UPSSampleUpdate.csv")]
    [TestMethod]
    public void UPSTrackTrace_DebatchAndConvertUPSUpdateFFToXml()
    {

        FFDisassembler ff = Disassembler.FlatFile().WithHeaderSpec<Vasanta.Int.Carrier.Schemas.Carriers.UPS.TrackAndTrace.TandTHeader>();
        ff.WithDocumentSpec<Vasanta.Int.Carrier.Schemas.Carriers.UPS.TrackAndTrace.TandTBody>();

        ReceivePipelineWrapper pipeline = Pipelines.Receive().WithDisassembler(ff);

        // Create the input message to pass through the pipeline
        MemoryStream stream = new MemoryStream();
        using (FileStream file = new FileStream("UPSSampleUpdate.csv", FileMode.Open, FileAccess.Read))
        {
            byte[] bytes = new byte[file.Length];
            file.Read(bytes, 0, (int)file.Length);
            stream.Write(bytes, 0, (int)file.Length);
        }

        IBaseMessage inputMessage = MessageHelper.CreateFromStream(stream);

        MessageCollection output = pipeline.Execute(inputMessage);

        Assert.AreEqual(15, output.Count);

    }

运行测试会引发以下错误：测试方法

谁能看到我哪里出错？

Answer 1

可能不是你。 BizTalk运行时中存在许多“事物”，这些“事物”不会被任何管道测试工具重新创建。

您最好的选择是下载源代码并在Visual Studio中运行它以查看它的中断位置。

旁注：我在BizTalk中运行所有测试。
