Firebase Authentication and flutter test
Hi FlutterDevs!I am fairly new to Flutter. One of the first things I attempted was a basic login flow for a Firebase app using Google, Facebook and email authentication. It worked great (well, a few problems with flutter_facebook_login that the author fixed quickly).I like having 100% code coverage for tests. For a while, I resigned myself to using flutter drive. I went so far as to set up dedicated CI runners with emulators active for the driver to run on and it is very nice, but there is no code coverage reporting with flutter drive. I like to know when I make a change that is potentially untested. I also like my tests to complete quickly, and flutter drive on an emulator is not exactly speedy-turnaround on changes.There was a lull between sprints to take some time out to try to tackle the problem. There was one esoteric reference to platform channels on one comment on one bug report hiding some pages down on a lucky Google search about the problem. Mockito and other mocking approaches just did not provide the degree of coverage required, but hijacking the device platform channels seemed like the "correct" way to go about it.The product of that lull between sprints was a pretty generic authentication package that has the option to run in a "mocked" mode under the test VM. Tests can even force the mocked platform channels to throw specific exceptions so the tests can easily trigger failure cases to achieve total code coverage.It does cover Facebook login, Google Sign-in, email sign-in, registering a new account via email, requesting a password reset email, and most of the error cases involved with those. It uses the Provider pattern, but also plays nicely with a Singleton pattern via GetIt.Instead of being "just another simple authentication" package, the important part is that it includes mocks for the platform channels so that firebase_auth, flutter_facebook_auth and google_sign_in can run under flutter test without rapid, unexpected disassembly on launch.For those that may also have run into this testing wall using Firebase for authentication, this might come in handy, if only to see how the platform channel mocks work to make your app testable with Firebase authentication.It is available on pub.dev as authenticator.The source repo, also listed on pub.dev, is available at gitlab.com/playscale-free/authenticator.I will likely, eventually use this for production unless someone more clever than myself (a low bar, to be sure) comes along with something better, or if someone in this sub can point me to a better wheel already made than the one I put together.I hope others can find this helpful. The Flutter community has been extremely helpful and encouraging as I learn an entirely different language, tool-set and libraries.
