Import fixtures into running firebase emulator

Question

I'm using emulator to run my unit tests, with fixtures to run more easily my integrations and units tests:

firebase emulators:start  --import=../fixtures/unit-tests

But when I'm writing something throught my test to firebase emulator, I cannot clear the data without removing all the fixtures.

For eg. there is this command:

firebase.clearFirestoreData({
  projectId: "my-project"
});

But this will remove all my data (fixture included). I want to clear my database without deleteting fixtures.

TLDR:

Is there a way to re-import fixtures into a running emulator or clear data without deleting fixtures?

Answer 1

I would suggest using the AdminApp abilities and store your fixtures as JSON files and create your collections before each test.
