I’ve been a GitLab member for 3 years now, but
became a GitLab staff member in January 2019. It’s be a whirlwind year so
far. Working for a hot startup moving at this pace has been the biggest change
I’ve had to experience since moving to Ontario. It’s been exciting and
wonderful, but that’s tangential to what this is about. At GitLab, I work on
the release team, and a big area I focus on is FEATURE FLAGS!
Feature Flags… what
Feature flags, if you haven’t had the opportunity, can be a big part of
continuous delivery. Martin Fowler loves them, and GitHub Actions

Taking the example from their docs, the following response would respond with
“Hello, world!” over the phone!

After recently using elixir and phoenix to recreate the API for
an old side project, I wanted to use Ecto’s embedded schemas, a schema
that is not persisted to an underlying table, to validate the JSON coming into
an API endpoint and get a workable domain object for the call before
transforming it into the model persisted for the DB.
We’ll look at how I set up the sign-up and sign-in endpoints using the embeded
schemas to validate the incoming JSON.

This is part 3 of our series. You can find part 1
here
and part 2
here.
This post’s topic is unit testing. We’ll be using Mocha,
Chai, and Sinon.JS. Everything will be run with
Karma on PhantomJS, so we will be able to run this
easily on a CI server such as Travis or Jenkins.
