Leave a failing test before you go on vacation - Freek Van der Herten's blog on Laravel, PHP and AI

Fri, 10 Jul 2026 22:12:45 +0000

Every year I dread coming back from vacation not because of the work, but because I have no idea where I left off. A failing test, a well-written TODO, and a slow first day back are all you need to ease back in.

When you're writing prompts, think about the model as a lazy pedant. How could it do something that's technically what you asked, but not at all what you wanted? Are you pushing it in a direction that's going to cause it to get desperate out and look for shortcuts? How could you clarify what you're asking to help the model do the right thing?

Red/green TDD - Agentic Engineering Patterns - Simon Willison's Weblog

Test-first development helps protect against both of these common mistakes, and also ensures a robust automated test suite that protects against future regressions. As projects grow the chance that a new change might break an existing feature grows with them. A comprehensive test suite is by far the most effective way to keep those features working.

How to fix Storybook screenshot testing | Tiger Oakes

Wed, 04 Dec 2024 22:02:41 +0000

As an alternative to Chromatic, I’ve been using Storybook’s Test Runner to power screenshot tests for Microsoft Loop. We configure the test runner to run in CI and take a screenshot of every story. However, the initial implementation based on the official Storybook docs was very flaky due to inconsistent screenshots of the same story. Here are some tips to reduce flakiness in your Storybook screenshot tests.

Unit testing React components without a DOM – simonsmith.io – Portfolio and blog of a London based front-end web developer

Thu, 18 Jun 2015 01:53:05 +0000

the idea of shallow rendering is to instantiate a component and get the result of its render method, which is a ReactElement. From here you can do things like check its props and children and verify it works as expected.

M/M/c queue - Wikipedia, the free encyclopedia

Wed, 22 May 2013 23:27:34 +0000

In queueing theory, the M/M/c queue is a multi-server queueing model.[1] In Kendall's notation it describes a system where arrivals form a single queue and are governed by a Poisson process, there are c servers and job service times are exponentially distributed.[2] It is a generalisation of the M/M/1 queue which considers only a single server. The model with infinitely many servers is the M/M/∞ queue.

Using Travis-CI with Python and Django - David Cramer's Blog

Wed, 02 Jan 2013 02:59:59 +0000

I’ve been using Travis-CI for a while now. Both my personal projects, and even several of the libraries we maintain at DISQUS rely on it for Continuous Integration. I figured it was about time to confess my undenying love for Travis, and throw up some notes about the defaults we use in our projects.
