We have many resources about testing and some about Firebase Realtime Database. It is almost like content creators agree on the subject of the content they publish.
I give a lot of space to other developers in this newsletter so I think I deserve to share some of my achievements: this week I joined the Flutter team at raywenderlich.com as a tech editor ?.
We're happy to welcome @_mvolpato

Better Bloc and Cubit Unit Testing
Did you ever have problems creating unit tests while using the BLoC pattern?
I surely did. This was one of the reasons why I am not using it anymore in the new apps I work on. Daniel Cardona Rojas comes to the rescue with this article, explaining his solution to the problem...
Generating Fake Data in Flutter using the Factory Pattern for Unit Testing

Unit testing DateTime.now() with the help of Dart extensions
Using DateTime.now() in your code makes unit testing more difficult. You do not know how much time passed between the call to DateTime.now() and the moment you test its value, so you cannot compare timestamps. Reme Le Hane proposes a solution based on extending DateTime. I wonder if you can separate the two static methods into two different extensions, so that you can declare the setter only for testing, to avoid accidentally use it in your production code.
Another solution is to have a World service that you can inject into other classes. This service will provide values like DateTime.now() in production, or the real value for some sensors, or GPS location. While during testing it can be fully mocked.
