Here's an idea: this page will be my test content. I'll include one of everything in here and use it for a very quick smoke-test

I don't currently have any [many] automated checks on this website – not something I'm proud of but a reality I'm willing to accept. I want to get up and running quickly and I'm still experimenting with this technology (Gatsby primarily) so borrowing a little is acceptable. If I start incurring interest on the debt I'll consider paying it back.

So for now I perform an unscripted manual check quite naturally. I look at the live site after I've made changes to it or added new content.

This page is somewhere I can note the features I have used on the site – a single place to quickly review everything. If I automate the natural checks I'm making I can start by checking what's on this page.


  1. Add a new feature to the site
  2. Include an example of it here
  3. Periodically check everything on this page is working

⚠️ Would I notice if I added new features and forgot to include them here?

⚠️ Would I notice if any of them broke?

🤖 And that's why we automate

Features of this site so far

JSX and Markdown

I'm not checking on this, it's a feature of gatsby-plugin-mdx

However, shortcodes are the JSX components that I pass in to MDXProvider and my automated checks wouldn't tell me if they were missing

WebGL model view projection

This article explores how to take data within a WebGL project, and project it into the proper spaces to display it on the screen. It assumes a knowledge of basic matrix math using translation, scale, and rotation matrices. It explains the three core matrices that are typically used when composing a 3D scene: the model, view and projection matrices. [...] WebGL_model_view_projection

I don't have "many" automated checks

Initially I wrote that I don't have "any" automated checks, then I started to notice automated checks that I had ignored:

  • Linting should happen whenever I save, assuming the format of the document is correct. If it fails I notice. This is a frequent, super cheap check that is very easy to keep green.

  • Deployment and build checks are another frequent, unobtrusive check that should not be underrated. When I push to my repo the automated pipeline runs build and deploy tasks. If there are errors then deployment fails and I notice.

Spotted a typo? Edit on Github

Unless otherwise stated I am the creator of all the text, images and code.

Generally I'm happy to share but let's talk first if you want to license or commercialise any of it
