Inspiration

mockfs is inspired by vfsStream. The code is completely different, but the underlying principle is the same — provide a way to mock the file system.

How It Differs

Here are some of the key differences between mockfs and vfsStream (v1.6.7):

  • Static analysis is cranked to the max to help prevent bugs

  • Support for using / as the root path

  • Support for partitions

  • Support for testing more complex failure scenarios

  • Support for multiple, more detailed quotas

  • Support for emulating different file systems (e.g. you can set up mockfs to behave like Windows)

  • Support for special files, such as /dev/null or /dev/random

  • Support for multibyte files

  • Support for opening the same file with two different handles

  • Everything has an interface and can easily be replaced (except the stream wrapper and the class that registers it)

  • Does not support flock() (yet)

  • Does not support mocking files with large content (yet)

Tools Used

For the Code

The number of tools used always seems endless, but these are the primary tools that mockfs uses extensively. See the dependency file for the full list.

For the Docs

Again, the list is likely endless, but these are the primary tools that make this site possible.

  • Bootstrap - The CSS framework used to style this site

  • Font Awesome - Scalable vector icons

  • Jekyll - A simple, extendable, static site generator

  • Jekyll Docs Theme - The original layout this site is based on (which in turn is based on the Bootstrap 3 documentation site). Note: This site’s version of the theme has been modified

  • Jekyll ToC - Table of Contents generator

  • Jekyll Heading Anchors - Generates anchors to the headers

  • Trianglify - Used to generate the triangular header background

  • Sass - The CSS is very Sass-y

  • Stickyfill - Polyfill for CSS position: sticky
