使用 moq + autofaq 不调用回调答案

【问题描述】：

我使用 moq 完成了一个单元测试来模拟对象，并且测试工作正常，现在我想使用 autofac +moq，但我遇到了一些问题。这是测试：

using (var mock = AutoMock.GetLoose())
{

    var issues = new List<Issue>();
    issues.Add(new Issue { Organization = "org", Repository = "repo", Number = 1 });
    issues.Add(new Issue { Organization = "org", Repository = "repo", Number = 2 });
    var numKeys = 0;

    mock.MockRepository.Create<IStorageService>()
        .Setup(myMock => myMock.GetBatchIssues(It.IsAny<string>(), 
                                               It.IsAny<string>(), 
                                               It.IsAny<IList<string>>()))
        .Callback((string org, string repo, IList<string> keys) => numKeys = keys.Count)
        .Returns(issues);

    var sut = mock.Create<IssueReceiveService>();

    var check = await sut.CheckInStorage("org", "repo", issues);
    Assert.AreEqual(issues.Count, numKeys);
}

sut.CheckInStorage 调用返回 null，变量 numKeys 未更新为正确值。这个测试只使用 moxk 就可以正常工作，所以我想我错过了一些如何使用 autoMock 配置模拟的东西。在哪里可以找到更多信息？

更新：

经过多次测试，我找到了解决方案

       using (var mock = AutoMock.GetLoose())
        {
            var issues = new List<Issue>();
            issues.Add(new Issue { Organization = "org", Repository = "repo", Number = 1 });
            issues.Add(new Issue { Organization = "org", Repository = "repo", Number = 2 });
            var numKeys = 0;

            mock.Mock<IStorageService>()
                .Setup(myMock => myMock.GetBatchIssues(It.IsAny<string>(), It.IsAny<string>(), It.IsAny<IList<string>>()))
                .Callback((string org, string repo, IList<string> keys) => numKeys = keys.Count)
                .Returns(issues);

            var sut = mock.Create<IssueReceiveService>();

            var check = await sut.CheckInStorage("org", "repo", issues);
            Assert.AreEqual(issues.Count, numKeys);
        }
