This folder contains (almost) our entire test suite. We split these tests into different subfolders in this directory.

In addition, we use HTML-Proofer to validate our built site. More on this below.

The tests in this directory include:

The content folder contains tests which are run over our Markdown and YAML files before they are built. These tests include:
- Ensuring that reusables are written correctly.
- Ensuring that there are no Liquid errors.
- Ensuring that there are no search errors.
The features folder contains tests that deal with how the site functions. These tests include:
- Whether the search links are valid.
- Whether the sidebar is working.
- Whether redirects are working.

There are two more types of tests that are controlled by HTML-Proofer:

HTML-Proofer validates that our internal content is working. That means that internal links are working, our images have alt tags, etc.
HTML-Proofer also validates our external content. That means URLs to external websites, external images, etc.
