使用AutoMoqCustomization我希望我的测试能够正常运行,但它失败了。
这是测试:
[Test, AutoMoqData]
public void Test1(
[Frozen] MyObject myObject,
[Frozen] Mock<IRepo> stubMock,
MyClass sut,
int objectId)
{
myObject.Id = objectId;
MyObject result = sut.GetById(objectId);
Assert.That(result.Id, Is.EqualTo(myObject.Id));
}
如果我添加一行代码,我可以使用它。但我不想这样做,因为它应该被推断?
stubMock.Setup(r => r.GetObject(It.IsAny<int>())).Returns(() => myObject);
MyClass有一个带有IRepo的构造函数。这就像一个魅力,因为如果我在我的测试中使用上面的行我有一个通过测试。
通常我在没有自动数据的情况下编写我的测试它更详细:
[Test]
public void Test3()
{
IFixture fixture = new Fixture();
int objectId = fixture.Create<int>();
var stubMock = fixture.Freeze<Mock<IRepo>>();
stubMock.Setup(r => r.GetObject(It.IsAny<int>())).Returns(() => fixture.Create<MyObject>());
fixture.Freeze<MyObject>(customise => customise.With(d => d.Id, objectId));
var sut = new MyClass(stubMock.Object);
MyObject result = sut.GetById(objectId);
Assert.That(result.Id, Is.EqualTo(objectId));
}
所以我的代码已经非常清晰,但是就像最后一个樱桃一样...我想任何想法???
如何运行:
添加Nuget包:
<packages>
<package id="AutoFixture" version="3.19.2" targetFramework="net45" />
<package id="AutoFixture.AutoMoq" version="3.19.2" targetFramework="net45" />
<package id="AutoFixture.NUnit2" version="3.19.2" targetFramework="net45" />
<package id="Moq" version="3.1.416.3" targetFramework="net45" />
<package id="NUnit" version="2.6.3" targetFramework="net45" />
</packages>
完整代码:
public class AutoMoqDataAttribute : AutoDataAttribute
{
public AutoMoqDataAttribute()
: base(new Fixture().Customize(new AutoMoqCustomization()))
{
}
}
[TestFixture]
public class Class1

}
public class MyClass
{
private readonly IRepo _test;
public MyClass(IRepo test) { _test = test; }
public MyObject GetById(int id) { return _test.GetObject(id); }
}
[Test, AutoMoqData]
public void Test1(
[Frozen] MyObject myObject, [Frozen] IRepo stubMock, MyClass sut, int objectId)
{
myObject.Id = objectId;
// expecting this commented line to be automatic because of the Frozen attribute on myObject?
// Mock.Get(stubMock).Setup(r => r.GetObject(It.IsAny<int>())).Returns(() => myObject);
MyObject result = sut.GetById(objectId);
Assert.That(result.Id, Is.EqualTo(myObject.Id));
}
[Test, AutoMoqData]
public void Test2(
[Frozen] MyObject myObject, [Frozen] Mock<IRepo> stubMock, MyClass sut, int objectId)
{
myObject.Id = objectId;
// expecting this commented line to be automatic because of the Frozen attribute on myObject?
// stubMock.Setup(r => r.GetObject(It.IsAny<int>())).Returns(() => myObject);
MyObject result = sut.GetById(objectId);
Assert.That(result.Id, Is.EqualTo(myObject.Id));
}
[Test]
public void Test3()
{
IFixture fixture = new Fixture();
int objectId = fixture.Create<int>();
var stubMock = fixture.Freeze<Mock<IRepo>>();
stubMock.Setup(r => r.GetObject(It.IsAny<int>())).Returns(() => fixture.Create<MyObject>());
fixture.Freeze<MyObject>(customise => customise.With(d => d.Id, objectId));
var sut = new MyClass(stubMock.Object);
MyObject result = sut.GetById(objectId);
Assert.That(result.Id, Is.EqualTo(objectId));
}
}

从3.20.0开始,您可以使用AutoConfiguredMoqCustomization
。这将自动配置所有模拟,以便其成员&#39;返回值由AutoFixture生成。
虚拟方法/属性/索引器将设置为使用AutoFixture延迟生成其返回值。如果该方法具有out
个参数,那么也会设置这些参数。
公共字段和密封属性将急切设置其值。
此测试现在应该通过:
[Test, AutoMoqData]
public void Test1(
[Frozen] MyObject myObject,
MyClass sut,
int objectId)
{
myObject.Id = objectId;
MyObject result = sut.GetById(objectId);
Assert.That(result.Id, Is.EqualTo(myObject.Id));
}

感谢@MarkSeemann的一些提示,我正在解决这个'问题'。
我开始使用AutoFixture.AutoMoq nuget包中的MockRelay类。我创建了一个重载MockRelayExtras,并将其添加到AutoMoqCustomozation。
这将反映在界面或抽象类上并相应地设置模拟
离。
Mock.Get(TInterface.Instance)
.Setup( i => i.Method( It.IsAny<TParamType>() ) )
.Returns( () => fixture.Create<TMethodResult>() );
现在这只适用于Interfaces和Abstract类(没有构造函数)
这是一个开始。代码将需要一些清理。此外,我希望其他人会喜欢,享受和使用它?
快乐的编码!
这是一个有效基础测试的工作解决方案,证明它有效。
