Biztalk 映射单元测试异常

Question

我正在尝试使用以下代码对地图进行单元测试，

protected string Map(TransformBase map, string xml)
        {
            StringWriter str = new StringWriter();
            XmlTextWriter writer = new XmlTextWriter(str);

            map.Transform.Transform(new XPathDocument(new StringReader(xml)), new XsltArgumentList(), writer);

            return str.ToString();
        }

调用如下，

[Test]
        public void Map_Test()
        {
            var result = Map(new TestMap(),File.ReadAllText(_dataDir.GetFiles("TestRequest.xml")[0].FullName));
            Assert.IsTrue(result.Contains("4323432"));
        }

这对大多数地图都适用，但是如果我使用外部程序集中的函数，这将不起作用并失败并显示错误

Result Message: System.Xml.Xsl.XslTransformException : Cannot find a script or an extension object associated with namespace 'http://schemas.microsoft.com/BizTalk/2003/ScriptNS0'.

Answer 1

无法参考外部程序集调试自定义 xslt。

Answer 2

最后，我用下面的代码（BT 2013 R2）做到了这一点，方法 Map 进行实际映射，returns 结果 xml，

参数，

map -> new object of the map type instance
xml -> source xml content
extObjects -> *_extxml.xml file content generated when executing validate instance on the map

代码

        protected string Map(TransformBase map, string xml, string extObjects = null)
        {
            string result = string.Empty;
            XslCompiledTransform transform = new XslCompiledTransform();
            XsltSettings setting = new XsltSettings(false, true);
            transform.Load(XmlReader.Create(new StringReader(map.XmlContent)), setting, new XmlUrlResolver());

            using (StringWriter writer = new StringWriter())
            {
                transform.Transform(XmlReader.Create(new StringReader(xml)),
                GetExtensionObjects(extObjects), XmlWriter.Create(writer));
                result = writer.ToString();
            }

            return result;
        }

        protected XsltArgumentList GetExtensionObjects(string extObjects)
        {
            XsltArgumentList arguments = new XsltArgumentList();
            if (extObjects == null)
                return arguments;

            XDocument extObjectsXDoc = XDocument.Parse(extObjects);
            foreach (XElement node in extObjectsXDoc.Descendants("ExtensionObject"))
            {
                string assembly_qualified_name = String.Format("{0}, {1}", node.Attribute("ClassName").Value, node.Attribute("AssemblyName").Value);
                object extension_object = Activator.CreateInstance(Type.GetType(assembly_qualified_name));
                arguments.AddExtensionObject(node.Attribute("Namespace").Value, extension_object);
            }
            return arguments;
        }

示例用法

    [Test]
    public void Map_Test()
    {
        var result = Map(new A_To_B()
            , File.ReadAllText("A.xml")
            , File.ReadAllText("A_To_B_extxml.xml"));
        Assert.IsNotNullOrEmpty(result);
    }
