About this course

WHY I WROTE THIS COURSE

Testing is an essential part of the software development life cycle. A good automated testing suite streamlines feedback, allowing rapid creation and tight control over specific application components. This course is a comprehensive introduction to testing Elixir applications with ExUnit. You’ll start with a review of unit testing principles before diving into writing tests with the ExUnit. You’ll build a comprehensive suite of unit tests before moving on to more advanced testing, including integration, end-to-end, and property-baste testing. In addition to the core Elixir environment, you’ll also develop tests for OTP, the Phoenix web framework, including JSON APIs and Ecto schematics. You’ll also explore refactoring for different platforms, server rendering, and design strategies. By the end of this course, you’ll be an expert in unit testing Elixir applications with ExUnit and ready to build robust, performant applications using Phoenix.

These are high-quality courses. Trust me the price is worth it for the content quality. Educative came at the right time in my career. I'm understanding topics better than with any book or online video tutorial I've done. Truly made for developers. Thanks

Just finished my first full #ML course: Machine learning for Software Engineers from Educative, Inc. ... Highly recommend!

You guys are the gold standard of crash-courses... Narrow enough that it doesn't need years of study or a full blown book to get the gist, but broad enough that an afternoon of Googling doesn't cut it.

Your courses are simply awesome, the depth they go into and the breadth of coverage is so good that I don't have to refer to 10 different websites looking for interview topics and content.
