We have some very exciting testing news to share! A few months ago, our teammate Jorge developed a comprehensive Lesson on Flutter Testing for Caster.IO. While Caster.IO has since ceased operations, we are very fortunate to be the new home for hosting Jorge’s testing content. The best part is: it’s now free!
We are very excited to make this content available to the developer community because we strongly believe that testing is a crucial part of the development process. It can make or break your application — lack of tests or offloading testing to a separate development team could lead to low-quality applications and last minute scrambles to squash bugs before launch. In contrast, integrating testing into the development process can increase confidence in your codebase and ensure that your app is able to ship at any point. This course will provide a nice foundation for Flutter developers looking to learn the fundamentals of testing, or serve as a handy reference for more experienced developers.
We plan to release the full course in three batches over the next few weeks according to the below schedule. You can view all of the content on this YouTube playlist.
