Django 3.2 Update for “Speed Up Your Django Tests” Released


I released my book “Speed Up Your Django Tests” over a year ago, in May 2020. Since then, we’ve seen two major Django releases, including a whole bunch of test-related changes, some of which I worked on as part of the book.


How to use Python’s HTTPStatus with Django

Snaily McSnailface says “use HTTPStatus”!

A “magic number” is the anti-pattern of using a number directly rather than storing it in a descriptive variable name. In web code HTTP status codes are often used as magic numbers, perhaps because web developers memorize common codes such as 200 and 404. In Python, we can avoid such magic with descriptive references from the standard library’s http.HTTPStatus enum.

I released my book Speed Up your Django Tests (SUYDT) just over a year ago, on the 18th May. It’s had a great reception, with 379 customers so far, many writing in to say how it has improved their test suites’ performance and readability.

“Where’s my coop?”

Here are three new security headers on the block:


Introducing the heroicons Python Package

Only iconography can tell us what is going on here.

heroicons is a free SVG icon set for your websites, from the creators of tailwindcss. SVG icons are great - they’re small, they sit inline in your HTML, and you can scaled and colour them with plain HTML and CSS. And heroicons is a great icon set - minimal, clear, and consistent.


django-feature-policy is now django-permissions-policy

This sheep doesn’t need permission to walk how it likes.

I created django-feature-policy in 2018 allow Django projects to control the draft security header Feature-Policy. Feature-Policy allows your site to restrict which origins can use some sensitive browser features, such as the the payments API or access to the webcam. This is valuable if you’re using any third party JavaScript. Whether such JavaScript comes from npm or an external script tag, you can protect against it doing some bad things with your users.
