I am trying to execute unit tests for Firestore. Below is the code snippet I am using:
import { getDoc, setDoc } from "@firebase/firestore";
import {
assertFails,
assertSucceeds,
initializeTestEnvironment,
RulesTestEnvironment,
} from "@firebase/rules-unit-testing"
describe('Creating a user', () => {
let alice;
let anon;
let testEnv;
beforeAll(async () => {
testEnv = await initializeTestEnvironment({
projectId: "PROJECT_ID"
})
})
beforeEach(() => {
alice = testEnv.authenticatedContext("alice", { user_id: "1" });
anon = testEnv.unauthenticatedContext();
});
test('alice can create a user', async () => {
await assertSucceeds(setDoc(alice.firestore(), '/users/alice'), { "name": "alice" });
})
});
The above code is based on the guidance provided in the official documentation, where they demonstrate a similar sample code:
// Assuming a Firestore app and the Firestore emulator for this example
import { setDoc } from "firebase/firestore";
const alice = testEnv.authenticatedContext("alice", { … });
// Use the Firestore instance associated with this context
await assertSucceeds(setDoc(alice.firestore(), '/users/alice'), { ... });
However, I encountered an error when running the code:
FirebaseError: Expected type 'DocumentReference', but it was: a custom Firestore object
This error occurred at the following line:
await assertSucceeds(setDoc(alice.firestore(), '/users/alice'), { "name": "alice" });I am puzzled by why this is not functioning correctly even after reviewing the official documentation. Can anyone offer insight into what might be the issue here?
