Automated Testing is essential to making your apps production-ready and to prevent introducing bugs when you change something. Flutter is an interesting case for testing because it is cross-platform. You should be writing also just one test for all your platforms making it easier to maintain.

Flutter offers three types of tests, unit, Widget, and integration tests. We will focus on widget and integration testing. Widget testing is new for Flutter, coming from Android and iOS. Integration testing is also something you want to make sure your app does not have issues running on iOS or Android.

When you do tests, you mock your dependencies and the network responses and requests. We will discuss how to mock your dependencies and network requests to have a stable test suite. Also, sometimes you also use plugins for Flutter that are using platform-specific code. Examples for these are Firebase Authentication and Firebase Database. We'll discuss how to mock these plugins so you can write widget and integration tests.

Of course, when doing automated tests, you also think about CI/CD. We will also discuss which services you can use to run your tests and how to set up your tests for CI/CD.
