Elixir Mentor

• German Velasco on PhoenixTest

  In this episode of the Elixir Mentor Podcast, I chat with German Velasco, creator of Elixir Streams and Phoenix Test. We explore test-driven development practices, the benefits of pair programming, and consulting experiences within the Elixir ecosystem.German shares his journey into Elixir development and discusses how adopting test-driven development has improved his coding workflow. He explains the philosophy behind Phoenix Test and demonstrates how proper testing can lead to more maintainable applications while reducing regression bugs.The conversation covers the important distinction between testing behavior versus implementation, practical approaches to achieving meaningful code coverage, and the collaborative benefits of pair and ensemble programming methodologies.We also discuss content creation for the Elixir community and how AI tools are changing programming workflows. This episode provides valuable insights for Elixir developers looking to improve their testing practices and team collaboration.Resources Mentioned:- Elixir Streams:https://elixirstreams.com- Phoenix Test:https://github.com/germsvel/phoenix_test- TDD Phoenix:https://tddphoenix.comConnect with German:- Twitter/X:https://x.com/germsvel- Website:https://www.germanvelasco.com/SUPPORT ELIXIR MENTOR- Elixir Mentor:https://elixirmentor.com
