testinghelpers

问题 I use the System.IO.Abstractions.TestingHelpers to mock FileSystem. In my class, I inject IFileSystem and use the instance to call _fileSystem.File.Exists and _fileSystem.File.Delete. In my test class, I would like to verify that the "Delete" method was called. It's easy by mocking only the IFile, but since I already mocked the FileSystem, I don't want to have to mock the Directory, Path and File on top of it. Is it possible to call something like _fileRepository.FileMock.Verify(x => x.Delete
