我正在尝试测试一个类的行为,当它通过委托工厂传递一个存根对象时。我制作了一个测试版本,其中所有类的依赖项(工厂除外)都作为 Mock 对象传递,并且它按预期工作。现在我正在尝试使用 AutoMock 让容器自动创建模拟。

我在使用 mock.Provide() 在 ClassUnderTest 的构造函数中传递委托工厂的具体值时遇到问题。(就像这个评论所暗示的)

我正在测试的课程:

public ClassUnderTest
{
 private readonly firstField;
 private readonly Func<string, ISecondField, IThirdField, IResultField> resultFieldFactory;
 private int someCounter = -1;

 public ClassUnderTest(IFirstField firstField, Func<string, ISecondField, IThirdField, IResultField> resultFieldFactory )
 {
  this.firstField = firstField;
  this.resultFieldFactory= resultFieldFactory;
 }

 public methodToTest()
 {
  IResultField resultField = resultFieldFactory(someString, secondFieldValue, thirdFieldValue);
  resultField.AddToList();
 }
}

业务逻辑模块:

public class BusinessLogicModule: Module
{
//some other things  that work

builder.RegisterType<ClassUnderTest>().As<IClassUnderTest>();
builder.RegisterType<SecondField>().As<ISecondField>();
builder.RegisterType<ThirdField>().As<IThirdField>();
builder.RegisterType<ResultField>().As<IResultField>();

}

测试类:

[TestClass]
public class TestClass()
{
 private IFirstField firstField;
 private Func<string, ISecondField, IThirdField, IResultField> funcToTriggerIResultFieldFactory;


 [TestInitialize]  
 public void Setup()
 {
  this.firstField= Resolve<IFirstField>();
  this.secondField= Resolve<ISecondField>();
  this.funcToTriggerIResultFieldFactory = Resolve<Func<string, ISecondField, IThirdField, IResultField>>();
 }


 [TestMethod]
 public void testMethodWithAutoMock()
 {
  using (var automock = AutoMock.GetLoose())
  {
    //trying to setup the SUT to get passed a "concrete" object
    autoMock.Provide(funcToTriggerIResultFieldFactory(stringValue, secondFieldValue, thirdFieldValue)); 

    var sut = autoMock.Create<IClassUnderTest>;

    sut.MethodToTest();
    //asserts
   }
 }

}

如果有任何迹象表明我做错了什么,我将不胜感激。我错过了什么?怎么可能修好?这是一个简单的语法修复还是我的测试方法有问题?

在此先感谢您的时间。

在您的示例中,当您调用时,autoMock.Provide()您不是传入工厂函数,而是调用工厂函数并传入结果(IResultField)。要解决此问题,请致电

autoMock.Provide(funcToTriggerIResultFieldFactory);

是使用自动模拟容器注册函数的完整示例。
