Implement testing for various packages

[moonmeister]

Most of the packages here don't have testing. I don't have time to implement but if anyone does it'd be super helpful in giving more confidence around package updates and deploys.

• gatsby-plugin-fastify - WIP: @moonmeister - test(gatsby-plugin-fastify): implement testing #97
• gatsby-plugin-relative-ci
• gatsby-plugin-reading-time
• gatsby-plugin-ackee-tracker

@moonmeister Do you know any example repos or packages that might serve as a good reference?

[moonmeister]

Yeah. I'd go checkout packages in the Gatsby repo. To keep things easy we'll probably use Jest and and the same setup patterns. I've worked on "gatsby-plugin-manifest" but there are lots of plugins with tests.

@moonmeister Thanks Alex! This is something I've been looking to get some experience with. I'll start poking around tonight 😄

If I have any specific questions - I might ping you on Discord!
