Provides a FileSystem factory class for allocating File, Directory and Link objects, with two implementations - one which in turn returns the real objects from dart:io, and one which returns mock versions. This allows tests to be written that make use of files and directories without having to create them on disk. The mock File/Directory/Link classes are not complete, but have sufficient functionality to work in most cases. The ultimate aim is to have complete mock implementations, as well as the ability to mock Windows file systems on Linux/Mac and vice-versa, to help with testing code for cross-platform correctness.

1. Depend on it

   Add this to your package's pubspec.yaml file:

   dependencies:
     mockable_filesystem: any

   If your package is an application package you should use any as the version constraint.

2. Install it

   If you're using the Dart Editor, choose:

   Menu > Tools > Pub Install
   

   Or if you want to install from the command line, run:

   $ pub install
   

3. Import it

   Now in your Dart code, you can use:

   import 'package:mockable_filesystem/filesystem.dart';

   or:

   import 'package:mockable_filesystem/mock_filesystem.dart';
