My solution didn’t work with default values. I added an erratum to my article :

Writing integration tests with Phoenix and React is easy and fun thanks to Hound, the browser automation and integration tests library for Elixir. Here’s a post I wrote about it with some tips and real test examples:

Happy coding!

Its easier than you think

I love Ecto and the composability of its queries, but it’s low-level, so I found myself reimplementing my own count, random, first, last, etc. functions in all my models/projects.

Plasm seeks to provide a high-level, generic, composable library of functions to make working with Ecto easier.

Last Thursday, at the Boston Elixir meetup, I gave a talk on programming autonomous robots with Elixir. The focus was on how Elixir/OTP makes it surprisingly easy to implement a multi-agent, “society of mind” architecture for Lego robots. In this blog post, I report on my latest progress and give a brief account of the talk, with links to video and slides.

Acceptance testing seems to be in its first steps in the Elixir ecosystem, but there are already some cool libs that can help us out to do it.

This blog post shows you how to do acceptance tests in Phoenix with Hound.

JSON Schema is a very useful, standards-track specification for defining schemas for JSON data. In this post, we explore using ExJsonSchema and a schema.json file to validate input and output data in an Elixir app.
