firebase
Allow database import at runtime
[REQUIRED] Environment info
firebase-tools: 8.4.0
Platform: MacOS
[REQUIRED] Test case
n/a
[REQUIRED] Steps to reproduce
- start the emulator with --import to preload an already exported data set.
- check on the new ui that the data is imported
- clear the database using REST api described at https://firebase.google.com/docs/emulator-suite/connect_and_prototype#clear_your_database_between_tests
- check on the ui, the data is gone
[REQUIRED] Expected behavior
The database is reset to its initial state with the imported data present
[REQUIRED] Actual behavior
The database is empty, the initial data is not restored.
@canatella that is currently working as intended although I can see how that can be confusing or frustrating as well.
It won't be technically feasible for us to import after every delete, but we can/should make it easier to import at runtime so that you can do multiple imports over the course of your testing. Would that help?
Sure! As long as there is a quick way to ensure that the database is in a known state between each tests. Thank you for being so reactive ;)
@canatella great, I have changed the title of the issue to reflect that. We're working on adding runtime import/export support to the Emulator UI and once we're done that we can probably figure out how to expose the same hooks to unit testing.

Just to know if i need to open a new issue or if this planned feature would cover my use case:
I need to populate the firestore emulator with data containing dates relative to the current date, so the static data saved / loaded by export / import feature do not work.
Currently i start the emulator and manually run a node script populating firestore with required data.
The feature you are working cover this use case?
E.g., it will be possible to define a node script (with runtime data manipulation) that is called when starting the firestore emulator?
@blikblum sorry but that is not something we are considering implementing, our focus is on static imports.
Just to capture my own thoughts here: what we need to make this happen is an import HTTP endpoint inside the Firestore emulator that we can call, just like we already have an export endpoint:
https://github.com/firebase/firebase-tools/blob/226ea560fb4dba574c87fcbceb11765f47931443/src/emulator/hubExport.ts#L88
@samtstern I was actually looking for that import endpoint in the firebase-tools 👍
Still hoping! ✌🏼
Not being able to import data while tests run is at this point a major deciding factor in using firebase or not. Hope this can get added soon.
Sorry to post a comment only to say that I would really very much love to have this, but I really would 😅 Still no update on this subject?
