c# - Application.Session.Categories.Remove不会一致地删除类别

我正在编写的集成测试有问题。我需要在测试结束时执行清除操作，方法是删除在测试过程中添加的Outlook中的类别（从可用类别列表中）。对于“已归档”类别，我按如下操作：

using Microsoft.Office.Interop.Outlook;

var outlookApplication = new Application();
outlookApplication.Session.Categories.Remove("Filed");

这无法删除类别，但不能一致。当我调试代码时，它可以工作，但在运行测试时却不能。

更新：
这是所有测试代码：

[TestFixture]
public class BootstrapperTest
{
    private bool containsFiled;
    private bool containsPending;
    private Application outlookApplication = new Application();

    [Test]
    public void CanCreateFiledCategory()
    {
        var bootstrapper = new Bootstrapper();
        bootstrapper.LoadCategoriesIntoOutlook(outlookApplication);
        var filedCategoryFound = outlookApplication.Session.Categories.Cast<Category>().Any(category => category.Name == "Filed");
        Assert.That(filedCategoryFound, Is.EqualTo(true));
    }

    [Test]
    public void CanCreatePendingCategory()
    {
        var bootstrapper = new Bootstrapper();
        bootstrapper.LoadCategoriesIntoOutlook(outlookApplication);
        var pendingCategoryFound = outlookApplication.Session.Categories.Cast<Category>().Any(category => category.Name == "Pending");
        Assert.That(pendingCategoryFound, Is.EqualTo(true));
    }

    [SetUp]
    public void Setup()
    {
        containsFiled = DoesCategoryNameExist(outlookApplication.Session.Categories, "Filed");
        containsPending = DoesCategoryNameExist(outlookApplication.Session.Categories, "Pending");
    }

    [TearDown]
    public void TearDown()
    {
        RemoveAllCategoriesFromOutlook();
    }

    private bool DoesCategoryNameExist(Categories categoryList, string categoryName)
    {
        return categoryList.Cast<Category>().Any(category => category.Name == categoryName);
    }

    private void RemoveAllCategoriesFromOutlook()
    {
        var containsFiledNow = DoesCategoryNameExist(outlookApplication.Session.Categories, "Filed");
        var containsPendingNow = DoesCategoryNameExist(outlookApplication.Session.Categories, "Pending");
        if (!containsFiled && containsFiledNow) outlookApplication.Session.Categories.Remove("Filed");
        if (!containsPending && containsPendingNow) outlookApplication.Session.Categories.Remove("Pending");
    }
}

它正在测试的方法：

public void LoadCategoriesIntoOutlook(Application outlookApplication)
{
    var categories = outlookApplication.Session.Categories;

    var filedCategoryNameExists = DoesCategoryNameAlreadyExist(categories, FiledCategoryName);
    var pendingCategoryNameExists = DoesCategoryNameAlreadyExist(categories, PendingCategoryName);
    var filedCategoryColourIsUsed = IsCategoryColorAlreadyUsed(categories, FiledCategoryColor);
    var pendingCategoryColourIsUsed = IsCategoryColorAlreadyUsed(categories, PendingCategoryColor);

    if (!filedCategoryNameExists)
    {
        if (filedCategoryColourIsUsed)
        {
            var categoryToBeChangedToFiled =
                    categories.Cast<Category>()
                              .Where(category => category.Color == FiledCategoryColor)
                              .FirstOrDefault();
            categoryToBeChangedToFiled.Name = FiledCategoryName;
        }
        else
        {
            categories.Add(FiledCategoryName, FiledCategoryColor);
        }
    }

    if (!pendingCategoryNameExists)
    {
        if (pendingCategoryColourIsUsed)
        {
            var categoryToBeChangedToPending =
                   categories.Cast<Category>()
                             .Where(category => category.Color == PendingCategoryColor)
                             .FirstOrDefault();
            categoryToBeChangedToPending.Name = PendingCategoryName;
        }
        else
        {
            categories.Add(PendingCategoryName, PendingCategoryColor);
        }
    }
}

最佳答案

您应该记录是否甚至通过调用Categories.Remove调用Trace.TraceInformation()，以查看在非DEBUG模式下运行时分支条件是否存在错误。 Categories.Remove确实可以可靠地工作，这一定是您的情况中存在错误。如果是这样，您将看不到日志记录语句。

private void RemoveAllCategoriesFromOutlook()
{
        var containsFiledNow = DoesCategoryNameExist(outlookApplication.Session.Categories, "Filed");
        var containsPendingNow = DoesCategoryNameExist(outlookApplication.Session.Categories, "Pending");
        if (!containsFiled && containsFiledNow)
        {
            outlookApplication.Session.Categories.Remove("Filed");
            Trace.TraceInformation("Deleted Filed Category!")
        }
        if (!containsPending && containsPendingNow)
        {
            outlookApplication.Session.Categories.Remove("Pending");
            Trace.TraceInformation("Deleted Pending Category!")
        }
}

同样，由于您是根据颜色创建的Categories（请参见filedCategoryColourIsUsed），即使通过重命名（containsFiled）而不是通过Category.Name = "Filed"创建了Categories.Add()，DoesCategoryNameExist仍可能返回FALSE。您的问题是Setup在您的Setup()测试治具中不考虑类别颜色。以下代码应解决此问题...

[SetUp]
public void Setup()
{
    containsFiled = DoesCategoryNameExist(outlookApplication.Session.Categories, "Filed") || IsCategoryColorAlreadyUsed(categories, FiledCategoryColor);
    containsPending = DoesCategoryNameExist(outlookApplication.Session.Categories, "Pending") || IsCategoryColorAlreadyUsed(categories, PendingCategoryColor);
}
