Don’t Forget to Test Your Flutter Code by Boris-Wilfried Nyasse

Testing is one of the most important phases of app development. You can’t build a high-quality app without testing it. The testing process requires precise planning and execution, but it’s also the most time-consuming part of development.

The Flutter framework provides comprehensive support for Flutter automated testing. Although Flutter is gaining traction, it can easily obscure the beauty of the Dart platform and the way developers can easily test their code.

In this session, we will look at how to build and automate your Flutter app testing.

Bio

Currently working as VP of Engineering for Stack Labs Canada (a consulting company
specialized in architecture and development of cloud solution),

I am a passionate Developer & Cloud/DevOps Architect, and above all passionate about tech, languages, infrastructure, and automation. I enjoy my journey to work with customer Technical leads, client executives and partners to manage and deliver successful migrations to Google Cloud solutions.

I enjoy my journey to ensure that the engineering trains run on time by creating an ideal environment for passionate people. My goal is just to inspire others to continuously improve and raise their standards at all levels of the team : follow best practices of software development. From the code analysis, testing and CI/CD knowledge.

Former founder and co-organizer of the Flutter Toulouse Meetup, it is fun to share my passion for Dart & Flutter. I’ve provided some talks to GDG and DevFest event ( Toulouse, Montpellier, London ).
