I'm writing a script that will generate extended A/B testing results. Is it possible to query Firebase A/B testing using API to get an experiment variant list, start date, end date, etc?
There currently is no API to get/manage the list of experiments for Firebase A/B testing. All management of experiments must be done through the Firebase console at the moment.
You might want to file a feature request, and keep an eye out on the Firebase blog and release notes for changes.

I am trying to setup flutter scripts for testing my classes that interface with my firestore database.
My current struggles are:
It seems that in order to use firebase_auth, I have to have a widget tree. I'm new to both flutter and firebase I am slowly building up my expertise by building classes one at a time, writing tests for them and then moving to the next class. Requiring the widget tree means I can't test the authorization logic independent of the GUI (e.g. What happens if I call signOut twice in my code even though the GUI logic only lets you press the button once?).
Mocking is insufficient. In order to mock, you need to know the expected behaviour for the tests to be representative. I've spent a lot of time trying to troubleshoot issues with futures, changing signed in states, and incorrect data formats. If I had written mocks, they wouldn't have matched how the real functions actually behave.
Mocking doesn't help me as I am also learning about the security rules for the database. I've definitely got code that works with lax security rules but there's something wrong with the current security rules.
Is there any way to write unit/integration tests for firebase_auth or firestore without mocking? I'm even happy using a local emulator/export of my database if that's a thing that's even possible.
Here are a number of the articles I have reviewed that are not what I am looking for:
A month of Flutter: mocking Firebase Auth in tests
Setup Unit test for Firebase User authentication with Mockito
How to create integration test for app with Firebase Auth?
Flutter Testing [4] - Firebase Auth App - Unit Testing
Mocking In Integration Tests with Flutter
Writing Unit Tests in Flutter with Firebase Firestore
Tutorial how to test with firebase #15245
According to this Github issue, it's not possible to run unit tests because native API calls are required.
Integration tests are supposed to be possible but the page from the Github Issue doesn't actually give an example of how to run the integration test.
Alright, I think I have found what I am looking for. The firebase team does a really good job showing how to test security rules in Unit testing security rules with the Firebase Emulator Suite.
What I did was I ran firebase init in my actual flutter project directory and this article Use the Firestore Emulator with Flutter shows how to access the emulator directly in flutter, however the command to initialize is now:
FirebaseFirestore.instance.useFirestoreEmulator('localhost', 8080);
Combining these, I think it should be possible to test whether or not one is writing the correct data within the correct format into the database along with ensuring the the data that's returned matches what's intended regardless of whether or not you are using Freezed, Json Serializable, dart:convert, etc...
My straight question is: since I am not interested in other Google Services, only Firestore, what is the difference between Firebase Cli and gcloud? Can I do all I need only with Firebase Cli or should I learn also gcloud?
I can easilly see that gcloud can handle more services than Firebase Cli. Also I can see Firebase Cli remenber me a lot the purpose of npm+ng cli when working with NodeJs/Angular (a simple analogy about scaffold/initialize/deploy). Nevertheless, our company will only use Firestore to take advantage of its Realtime Database pushing events to our mobile application.
I use Firebase Cli to type in my Windows command line and create a project in Firebase. I can see the result in Firebase Console and I also can see it in Console Cloud Plataform.
For me, who is total beginner with Google Cloud Plataform, it is a bit confused when prefer one over other. For instance, let's say I want to query data from Firebase Crashlytics from command line instead of logging from my Browser. Is it possible to use either Firebase Cli or gcloud? If both, which one is recommended for some company only interested in Firestore project?
This week I am struggling to figure out how to extract metrics regard my Firestore project and if I don't know what is the recommended tool for reach this task it make even harder to find the first steps. By extracting I don't mean see a beatifull dash in Google Console. I mean consume an endpoint providing me Firestore Metrics or, even better, subscribe my endpoint to Firestore project which will be called every time some issue happens (Other question asking exactly about getting Firestore metrics)
It is confusing and is partly the result of Google's acquisition of Firebase, the creation of what's now called Firestore (which is the unification of the original Firebase backend technology and Google Cloud Datastore), and that Google provides the Firestore service to both its Firebase and Google Cloud developer audiences.
As you've gathered, Google Cloud's CLI (Cloud SDK aka gcloud) and the Firebase CLI overlap in functionality. However, importantly:
both CLIs interact with a shared set of Google services (e.g. Firestore, identity, logging etc.).
there are some Google Cloud services not part of Firebase and vice versa
If you're focused on Firebase, you should be to able to stick with the Firebase CLI and continue to interact with Google's services through this Firebase lens.
If you include Google Cloud Platform services that aren't part of Firebase, you'll need to then consider using gcloud but importantly, you can either:
continue to use the Firebase CLI for the Firebase services;
use gcloud to interact with some (not all!) of the Firebase services (e.g. Firestore).
Over time, I assume (!) the remain discord between these 2 platforms will diminish.
If you consider both platforms as the result of (an ongoing?) unification since the acquisition, hopefully, these discrepancies will be more understandable and less frustrating.
Where you do find inconsistencies and frustrations, ensure Google knows by submitting feature requests and bugs.
I'm setting up a dataflow in Google Cloud Platform. I have retrieved data from IoT devices and sent to Pub/Sub, and I now want to store in Firestore. I am using Firebase for my web app where data should be displayed etc.
I realise this should be a simple task, but am still not finding too much information about it (probably too straight forward). Have looked at using Cloud Functions to retrieve from Pub/Sub and add to Firestore, which ought to work (although I got stuck at credentials), but is there an easier way that I am missing?
Your thinking on using Cloud Functions as the recipient of a PubSub message coming from Cloud IoT Core and in that Cloud Function performing an insert into Firestore is exactly correct.
Here is an example showing just that:
https://blog.usejournal.com/build-a-weather-station-with-google-cloud-iot-cloud-firestore-mongoose-os-android-jetpack-350556d7a
If we Google search using "gcp pubsub firestore" we will find many others.
If you use this technique and run into puzzles/problems, don't hesitate to raise new questions (but first search and see if they have been raised before). In your new questions, please be as detailed as possible. There are many samples available for all sorts of related areas. Have a study of these.
I'm teaching myself to use Flutter and I'm making an app that queries The Movie Database API. Currently, I'm having the client query the API on launch but I'm thinking this is not the most efficient way of doing it, and I would rather have the client query a backend service like Firebase to get the same data.
I would appreciate some guidance into where to start in order to setup a periodical process to query the API and use the results as entries into a Firestore DB. I've looked online but I might be using suboptimal keywords since I haven't found a good tutorial or example for this.
Thanks.
You can use Firebase Cloud Functions to build code that runs on Firebase servers to fill your Firebase database, but you can only make HTTP requests to non-Google addresses if you use a paid plan.
https://firebase.googleblog.com/2017/03/how-to-schedule-cron-jobs-with-cloud.html explains how to invoke periodic tasks with Cloud Functions. It utilizes Google AppEngine for that because Cloud Functions doesn't provide that out of the box.
I want to test my Firebase data access layer with direct access to Firebase.
Is flutter drive the only way to run such tests, or are there other ways like running in emulator using flutter test?
What are the possible approaches and how can I set them up?
I'm not aware of a way to talk to a real database with flutter test currently, because there's no Firebase SDK to do the talking to the network. You probably wouldn't want this anyway, because it could make your tests nondeterministic or flaky if the data changes or the Firebase servers aren't accessible.
Some plugins, like shared_preferences, have an API for providing mock values. You could do something like that for the firebase_database plugin, either as a pull request to the first-party repo or by calling MethodChannel.setMockMethodCallHandler and BinaryMessages.handlePlatformMessage in your test code to simulate what the native side would be doing.
