Testing Server Side Jeffrey

Jeffrey Matthias

Friday, 03 March 2023


In person


From 9am to 6pm


Testing server code can be daunting. In the worse-case you either end up with too little test coverage (and every second change will result in an outage) or you have over-engineered your tests and your testing (and every one-hour change requires you to spend another ten hours fixing broken tests). This training aims to provide you with an overview of different testing approaches, frameworks and tools. And also a lot of guidance on what to use when and where and how to get it right. The training will be delivered in four lectures/modules. Every module will have 30-45 mins of slides followed by 45-60 mins of practical exercises. There will also be guided discussions to use/share the experience of the people in the room. The training is based on the book Testing Elixir by Jeffrey Matthias and Andrea Leopardi.

  • Unit-testing - The base line
  • Integration-testing - Make systems work
  • Ecto and Phoenix - The two pillars
  • Property-based testing - The life safer


The attendees will walk away from this training with a clear understand what testing options/approaches are available to them and which one to pick/use in a given situation. The attendees will have also learned valuable lessons-learned from the instructors experience when/while testing a large-scale SaaS platform (at Community.com). Furthermore the attendees will walk away from the training with a lot of working blue-print code that shows how to use the frameworks and tools.


Intermediate users


The training will be hands-on. You need to have elixir experience (1+ years). You need to bring your own laptop (details on what needs to be installed will be provided). Reading the book before the training will help, but is not a requirement.
