RulesTestEnvironment interface

An object used to control the rules unit test environment. Can be used to create RulesTestContext for different authentication situations.

Signature:

export interface RulesTestEnvironment 

Properties

Property Type Description
emulators { database?: HostAndPort; firestore?: HostAndPort; storage?: HostAndPort; } A readonly copy of the emulator config specified or discovered at test environment creation.
projectId string The project ID specified or discovered at test environment creation.

Methods

Method Description
authenticatedContext(user_id, tokenOptions) Create a RulesTestContext which behaves like an authenticated Firebase Auth user.Requests created via the returned context will have a mock Firebase Auth token attached.
cleanup() At the very end of your test code, call the cleanup function. Destroy all RulesTestContexts created in test environment and clean up the underlying resources, allowing a clean exit.This method does not change the state in emulators in any way. To reset data between tests, see clearDatabase(), clearFirestore() and clearStorage().
clearDatabase() Clear all data in the Realtime Database emulator namespace.
clearFirestore() Clear data in the Firestore that belongs to the projectId in the Firestore emulator.
clearStorage() Clear Storage files and metadata in all buckets in the Storage emulator.
unauthenticatedContext() Create a RulesTestContext which behaves like client that is NOT logged in via Firebase Auth.Requests created via the returned context will not have Firebase Auth tokens attached.
withSecurityRulesDisabled(callback)

RulesTestEnvironment.emulators

A readonly copy of the emulator config specified or discovered at test environment creation.

Signature:

readonly emulators: {
        database?: HostAndPort;
        firestore?: HostAndPort;
        storage?: HostAndPort;
    };

RulesTestEnvironment.projectId

The project ID specified or discovered at test environment creation.

Signature:

readonly projectId: string;

RulesTestEnvironment.authenticatedContext()

Create a RulesTestContext which behaves like an authenticated Firebase Auth user.

Requests created via the returned context will have a mock Firebase Auth token attached.

Signature:

authenticatedContext(user_id: string, tokenOptions?: TokenOptions): RulesTestContext;

Parameters

Parameter Type Description
user_id string the User ID of the user. Specifies the value of "user_id" and "sub" on the token
tokenOptions TokenOptions custom claims or overrides for Firebase Auth token payloads

Returns:

RulesTestContext

Example

const alice = testEnv.authenticatedContext('alice');
await assertSucceeds(getDoc(alice.firestore(), '/doc/readable/by/alice'), { ... });

RulesTestEnvironment.cleanup()

At the very end of your test code, call the cleanup function. Destroy all RulesTestContexts created in test environment and clean up the underlying resources, allowing a clean exit.

This method does not change the state in emulators in any way. To reset data between tests, see clearDatabase(), clearFirestore() and clearStorage().

Signature:

cleanup(): Promise<void>;

Returns:

Promise<void>

RulesTestEnvironment.clearDatabase()

Clear all data in the Realtime Database emulator namespace.

Signature:

clearDatabase(): Promise<void>;

Returns:

Promise<void>

RulesTestEnvironment.clearFirestore()

Clear data in the Firestore that belongs to the projectId in the Firestore emulator.

Signature:

clearFirestore(): Promise<void>;

Returns:

Promise<void>

RulesTestEnvironment.clearStorage()

Clear Storage files and metadata in all buckets in the Storage emulator.

Signature:

clearStorage(): Promise<void>;

Returns:

Promise<void>

RulesTestEnvironment.unauthenticatedContext()

Create a RulesTestContext which behaves like client that is NOT logged in via Firebase Auth.

Requests created via the returned context will not have Firebase Auth tokens attached.

Signature:

unauthenticatedContext(): RulesTestContext;

Returns:

RulesTestContext

Example

const unauthed = testEnv.unauthenticatedContext();
await assertFails(getDoc(unauthed.firestore(), '/private/doc'), { ... });

RulesTestEnvironment.withSecurityRulesDisabled()

Signature:

withSecurityRulesDisabled(callback: (context: RulesTestContext) => Promise<void>): Promise<void>;

Parameters

Parameter Type Description
callback (context: RulesTestContext) => Promise<void>

Returns:

Promise<void>
