Using minitest to regression-test your Jekyll static site

I recently had to upgrade my blog, which involved changes such as:

• Replacing a sitemap plugin
• Upgrading from jekyll 2.5.3 to 3.8.4
• Upgrading from jekyll-assets 0.7.8 to 3.0.11
• (etc)

The upgrading process was not trivial, and some parts (e.g. RSS, sitemap, or twitter cards tags) are not immediately visible, so I decided to add unit tests on the generated content.
