我尝试按照有关测试单元测试的答案进行操作，但是当我尝试枚举捆绑中的文件进行测试时，我总是得到零计数。

以下代码有什么问题？

[TestFixture]
public class BundleConfigTests
{
    private TestVirtualPathProvider _vpp;
    private BundleCollection _bundles;
    private HttpContextBase _httpContext;

    [SetUp]
    public void SetUp()
    {
        _vpp = new TestVirtualPathProvider();
        var directory = new TestVirtualPathProvider.TestVirtualDirectory("/css/");
        directory.DirectoryFiles.Add(new TestVirtualPathProvider.TestVirtualFile("/css/global.css", "correct"));
        directory.DirectoryFiles.Add(new TestVirtualPathProvider.TestVirtualFile("/css/global2.css", "correct"));
        directory.DirectoryFiles.Add(new TestVirtualPathProvider.TestVirtualFile("/css/ie8.css", "correct"));
        directory.DirectoryFiles.Add(new TestVirtualPathProvider.TestVirtualFile("/css/buttons.css", "correct"));
        directory.DirectoryFiles.Add(new TestVirtualPathProvider.TestVirtualFile("/css/buttons2.css", "correct"));
        directory.DirectoryFiles.Add(new TestVirtualPathProvider.TestVirtualFile("/css/navigation.css", "correct"));
        directory.DirectoryFiles.Add(new TestVirtualPathProvider.TestVirtualFile("/css/dealticket.css", "correct"));
        directory.DirectoryFiles.Add(new TestVirtualPathProvider.TestVirtualFile("/Content/themes/base/jquery-ui.css", "correct"));
        directory.DirectoryFiles.Add(new TestVirtualPathProvider.TestVirtualFile("/Content/Site.css", "correct"));
        directory.DirectoryFiles.Add(new TestVirtualPathProvider.TestVirtualFile("/css/jquery.loadmask.css", "correct"));
        _vpp.AddDirectory(directory);

        BundleTable.VirtualPathProvider = _vpp;

        _bundles = BundleTable.Bundles;
        _httpContext = MockRepository.GenerateMock<HttpContextBase>();
    }

    [Test]
    public void RegisterBundles_Always_AllCssFilesToEachBundle()
    {
        BundleConfig.RegisterBundles(_bundles);

        foreach (var bundle in _bundles.GetRegisteredBundles())
        {
            var bundledFiles = bundle.EnumerateFiles(new BundleContext(_httpContext, _bundles, bundle.Path));

            // bundledFiles has zero count!
            // Also tried getting the non-public Items property of the bundle which is also zero.
            // var items = bundle.GetType().GetProperty("Items", BindingFlags.NonPublic | BindingFlags.Instance).GetValue(bundle, null);

            foreach (var file in _vpp.GetDirectory("~/css/").Files.OfType<BundleConfigTests.TestVirtualPathProvider.TestVirtualFile>())
            {
                Assert.True(bundledFiles.Any(bf => bf.IncludedVirtualPath == file.VirtualPath), file.VirtualPath + " not bundled");
            }
        }
    }

    // Used this test this TestVirtualPathProvider by @HaoKung (https://stackoverflow.com/a/11441016/169034)
}

我的 RegisterBundles 实现是：

public static void RegisterBundles(BundleCollection bundles)
{
  bundles.Add(new Bundle("~/bundles/styles-" + Cultures.English)
          .Include("~/css/global.css")); // This item is never in the items collection of the bundle in my unit tests.
  bundles.Add(new Bundle("~/bundles/styles-" + Cultures.Chinese));
}

我也在使用那个例子，发现了这个问题。{version}我通过在 my 中使用 abundle.Include()并附-1.0.css加到虚拟文件名来修复它。不知道它为什么起作用，但这是我可以在包中获取文件的唯一方法。希望有帮助。

//Setup the vpp to contain the files/directories
var vpp = new TestVirtualPathProvider();
var directory = new TestVirtualPathProvider.TestVirtualDirectory("/dir/");
directory.DirectoryFiles.Add(new TestVirtualPathProvider.TestVirtualFile("/dir/select2-1.0.css", "correct"));
vpp.AddDirectory(directory);

// Setup the bundle
var bundleCollection = new BundleCollection();
var bundle = new ScriptBundle("~/bundles/test");
BundleTable.VirtualPathProvider = vpp;
bundle.Include("~/dir/select2-{version}.css");
bundleCollection.Add(bundle);
var mockHttpContext = new Mock<HttpContextBase>();

// Verify the bundle repsonse
var context = new BundleContext(mockHttpContext.Object, bundleCollection, vpp.ToString());
var response = bundle.GenerateBundleResponse(context);
Assert.Equal(@"correct", response.Content);
