Not that long ago, I wrote how to pair RxSwift with MVVM architecture in an iOS project. Even if I refactored my code to be reactive, I omitted to mention the unit tests. Today I’ll show step by step how to use RxTest to unit test your code.
For last couple weeks, I’ve worked a lot about how to integrate RxSwift into an iOS project but I wasn’t fully satisfied with the view model. After reading many documentation and trying on my side, I’ve finally found a structure I’m happy with.
It took me quite some time to get into Reactive Programming and its variant adapted for iOS development with RxSwift and RxCocoa. However, being fan of MVVM architecture and using an observer design pattern with it, it was natural for me to revisit my approach and use RxSwift instead. Thats what I’m going to cover in this post.
