我有以下代码：

var boundArgument = new BoundArgumentOption
{
    PatientId = patientId
};

var mockRepositoryFactory = A.Fake<IRepositoryFactory>();

var sut = new HtmlOutputBuilder(mockRepositoryFactory);

var patientRecord = // Some record;

var mockRepository = A.Fake<IRepository>();
A.CallTo(() => mockRepository.Get(boundArgument)).Returns(patientRecord);
A.CallTo(() => mockRepositoryFactory.Create(boundArgument)).Returns(mockRepository);

string actualResult = sut.BuildReport(boundArgument);

actualResult.Should().Be(expectedHtmlContent);

并且通过了测试。

然后我尝试使用 AutoFixture，如下所示：

var fixture = new Fixture().Customize(new AutoFakeItEasyCustomization());

var boundArgument = fixture.Create<BoundArgumentOption>();

var mockRepositoryFactory = A.Fake<IRepositoryFactory>();

fixture.Freeze(mockRepositoryFactory);

var sut = fixture.Create<HtmlOutputBuilder>();

var patientRecord = //Some record;

boundArgument.PatientId = patientId;

var mockRepository = A.Fake<IRepository>();
A.CallTo(() => mockRepository.Get(boundArgument)).Returns(patientRecord);

A.CallTo(() => mockRepositoryFactory.Create(boundArgument)).Returns(mockRepository);

string actualResult = sut.BuildReport(boundArgument);

actualResult.Should().Be(expectedHtmlContent);

失败了。特别是，patientRecord在第二种情况下，没有正确填充。

我在这里做错了什么？

注意：我无法编译您提供的测试.. 但是您似乎要做的就是：

fixture.Inject(mockRepositoryFactory);

您可以尝试以下方法：

[Fact]
public void TestWithAutoFixtureImperatively()
{
    // Fixture setup
    var fixture = new Fixture()
        .Customize(new AutoFakeItEasyCustomization());

    var expectedRecord = fixture.Create<string>();
    var boundArgOption = fixture.Create<BoundArgumentOption>();

    var repositoryStub = A.Fake<IRepository>();
    A.CallTo(() => 
        repositoryStub
            .Get(boundArgOption))
            .Returns(expectedRecord);

    var repositoryFactoryStub = A.Fake<IRepositoryFactory>();
    A.CallTo(() => 
        repositoryFactoryStub
            .Create(boundArgOption))
            .Returns(repositoryStub);

    fixture.Inject(repositoryFactoryStub);

    var sut = fixture.Create<HtmlOutputBuilder>();

    // Exercise system
    string result = sut.BuildReport(boundArgOption);

    // Verify outcome
    result.Should().Be(expectedRecord);

    // Teardown
}

我们注入了IRepositoryFactory相同的、注入的实例将在 SUT 中传递。

或者，您也可以通过xUnit.net扩展名以声明方式使用 AutoFixture ：

[Theory, AutoDomainData]
public void TestWithAutoFixtureDeclaratively(
    string expectedRecord,
    BoundArgumentOption boundArgOption,
    Fake<IRepository> repositoryStub,
    [Frozen]Fake<IRepositoryFactory> repositoryFactoryStub,
    HtmlOutputBuilder sut)
{
    // Fixture setup
    A.CallTo(() =>
        repositoryStub
            .FakedObject
            .Get(boundArgOption))
            .Returns(expectedRecord);

    A.CallTo(() =>
        repositoryFactoryStub
            .FakedObject
            .Create(boundArgOption))
            .Returns(repositoryStub.FakedObject);

    // Exercise system
    string result = sut.BuildReport(boundArgOption);

    // Verify outcome
    result.Should().Be(expectedRecord);

    // Teardown
}

AutoDomainDataAttribute定义为：

internal class AutoDomainDataAttribute : CompositeDataAttribute
{
    internal AutoDomainDataAttribute()
        : base(
            new AutoDataAttribute(
                new Fixture().Customize(
                    new AutoFakeItEasyCustomization())))
    {
    }
}
