c# - storyQ 将参数传递给函数

Question

这是我的测试，我想将一个变量传递给函数 ImageSelectionDatabaseIsValidAllTotalGainsAssigned 我希望它为 8 和 7 检查断言一次。

但是您不能将参数传递给函数并调用 .Then()

你能解释一下如何做到这一点吗？

    [Test]
    public void Set8NewImagesAndTotalGainsRemove2ImagesTest()
    {
        _imageSelectionStory.WithScenario("init new ImagesSelectionViewModel and load 8 new images from database and assign total gain 1,2 to all, and then remove 2 images")
            .Given(InitImageSelectionViewModelAndDatabaseImages)
            .When(SetNewImagesFromDatabase)
            .And(UpdateAssignedToTotalGains)
            .Then(ImageSelectionDatabaseIsValidAllTotalGainsAssigned)
            .Execute();
    }


    private void ImageSelectionDatabaseIsValidAllTotalGainsAssigned()
    {
        foreach (var image in _imagesSelectionViewModel.Images)
        {
            CollectionAssert.AreEqual(new List<double>{1,2}, image.AssignedToTotalGain);
        }
        Assert.AreEqual(8, _imagesSelectionViewModel.Images.Count);
        Assert.True(_imagesSelectionViewModel.IsValid());
    }

            private void ImageSelectionDatabaseIsValidImagesAllTotalGainsAssigned(int expected)
            {
               foreach (var image in _imagesSelectionViewModel.Images)
              {
                   CollectionAssert.AreEqual(new List<double> { 1, 2 }, image.AssignedToTotalGain);
              }
              Assert.AreEqual(expected, _imagesSelectionViewModel.Images.Count);
              Assert.True(_imagesSelectionViewModel.IsValid());
            }
