如何模拟autofac的自动生成的委托工厂？

Question

我正努力为我的一个课程进行单元测试.我想注入我的工厂,而不是autofac解决的自动生成的工厂.如何将自己的函数注册为代理来替换自动生成的委托工厂？

我的代码看起来像这是大纲形式:

interface IEntryImporter { ... }

class EntryImporter : IEntryImporter {
    public EntryImporter(ISeries series, IMatch match, Entry.Factory entryFactory) {
        :
    }
    :
}

interface IEntry : { ... }
class Entry : IEntry {
    public delegate IEntry Factory();
    public Entry() { ... }
}

interface IMatch : { ... }
class Match : IMatch { ... }

interface ISeries : { ... }
class Series : ISeries { ... }

void IEntry MyEntryFactory() {
    var entry = new Mock<IEntry>();
    :
    return entry.Object;
}

void TestMe() {
    ContainerBuilder builder = new ContainerBuilder();
    builder.RegisterType<Entry>().As<IEntry>();
    builder.RegisterType<Match>().As<IMatch>();
    builder.RegisterType<Series>().As<ISeries>();
    builder.RegisterType<EntryImporter>.As<IEntryImporter>();

    var series = new Mock<ISeries>(MockBehavior.Strict);
    builder.RegisterInstance<ISeries>(series.Object);

    var match = new Mock<IMatch>(MockBehavior.Strict);
    builder.RegisterInstance<IMatch>(match.Object);

    // How to register MyEntryFactory as Entry.Factory for autofac to resolve?

    using(var container = builder.Build()) {
        var importer = container.Resolve<IEntryImporter>();
        :
    }
}

您可以注册自己的方法以用作模拟条目工厂,如下所示:

builder.Register<Entry.Factory>(c => MyEntryFactory).As<Entry.Factory>();

我已将您的示例作为GitHub上的Autofac Answers的一部分工作.
