Map actual directories in MockFileSystem

[m-gallesio]

Greetings.

Is there a way to make a part of a MockFileSystem point to an actual directory / file?
In our scenario we need to be able to read (not write) some actual files which are bundled with the application (mostly images and templates) while still mocking the rest.

A way I can think of is reading the target directory and mapping all of it manually when initialising the MockFileSystem, but I wonder if there is some built-in method / shortcut for this.

Currently there is no such built-in functionality. We only have a method to initialize the MockFileSystem with the embedded resources from an assembly (see InitializeEmbeddedResourcesFromAssembly). But I see your use case and would be open to a pull request that initializes the file system with the files and directories from a given directory.

Understood, we will investigate further and consider contributing when we will get to the point of concretely needing this.
