The preferred approach to ensuring uniqueness is to construct channel names as a combination of: +1. A **descriptive part** that refers to the test (e.g., including the name of the test, or the ID of the spec item) +2. A **random part** that's sufficiently large to ensure the risk of collision is negligible (e.g., a base64-encoded 48-bit number) + +Example: `test-RSL1-publish-${base64(random_bytes(6))}` + +#### Authenticated Endpoints + +Do **not** use `time()` for testing authentication because it does not require authentication.

Native tokens, and the correct handling of token requests, should be tested in a way that's as independent as possible from testing the mechanisms relating to handling tokens in requests and the token renewal process via `authCallback` and `authUrl`. + +### Unit Tests with Tokens + +For unit tests, since the token string is opaque to the library, any arbitrary string can be used as a token value. + +## Avoiding Flaky Tests + +### Polling Instead of Fixed Waits + +Do not use fixed `WAIT` durations that may cause flakiness due to timing variations.

Use a short TTL (e.g., 2 seconds) +2. Wait the TTL duration +3. Poll an endpoint at intervals (e.g., 500ms) until rejection +4. Set a reasonable timeout (e.g., 5 seconds after TTL) + +This approach avoids flakes from minor clock skew while minimizing test duration. + +## Spec Point Coverage + +### REST Client (RSC) +| Spec | Test File | Description | +|------|-----------|-------------| +| RSC1 | uts/test/realtime/unit/client/client_options.md | String argument detection | +| RSC6 | unit/client/stats.md | Application statistics | +| RSC7 | uts/test/rest/unit/rest_client.md | Request headers | +| RSC8 | uts/test/rest/unit/rest_client.md | Protocol selection | +| RSC13 | uts/test/rest/unit/rest_client.md | Request timeouts | +| RSC15 | unit/client/fallback.md | Host fallback | +| RSC16 | unit/client/time.md | Server time | +| RSC18 | uts/test/rest/unit/rest_client.md | TLS configuration | + +### REST Authentication (RSA) +| Spec | Test File | Description | +|------|-----------|-------------| +| RSA1-4 | unit/auth/auth_scheme.md | Auth method selection | +| RSA4b4, RSA14 | unit/auth/token_renewal.md | Token expiry and renewal | +| RSA7 | unit/auth/client_id.md | clientId from options | +| RSA8c | unit/auth/auth_callback.md | authUrl queries | +| RSA8d | unit/auth/auth_callback.md | authCallback invocation | +| RSA12 | unit/auth/client_id.md | clientId in TokenParams | + +### REST Channel (RSL) +| Spec | Test File | Description | +|------|-----------|-------------| +| RSL1 | unit/channel/publish.md | Channel publish | +| RSL1k | unit/channel/idempotency.md | Idempotent publishing | +| RSL2 | unit/channel/history.md | Channel history | +| RSL4, RSL6 | unit/encoding/message_encoding.md | Message encoding | + +### REST Presence (RSP) +| Spec | Test File | Description | +|------|-----------|-------------| +| RSP1 | unit/presence/rest_presence.md | RestPresence accessible via channel | +| RSP3 | unit/presence/rest_presence.md | RestPresence#get | +| RSP3a1 | unit/presence/rest_presence.md | get() limit parameter | +| RSP3a2 | unit/presence/rest_presence.md | get() clientId filter | +| RSP3a3 | unit/presence/rest_presence.md | get() connectionId filter | +| RSP4 | unit/presence/rest_presence.md | RestPresence#history | +| RSP4b1 | unit/presence/rest_presence.md | history() start/end params | +| RSP4b2 | unit/presence/rest_presence.md | history() direction param | +| RSP4b3 | unit/presence/rest_presence.md | history() limit param | +| RSP5 | unit/presence/rest_presence.md | Presence message decoding | + +### Realtime Client (RTC) +| Spec | Test File | Description | +|------|-----------|-------------| +| RTC1a | uts/test/realtime/unit/client/realtime_client.md | echoMessages option | +| RTC1b | uts/test/realtime/unit/client/realtime_client.md | autoConnect option | +| RTC1c | uts/test/realtime/unit/client/realtime_client.md | recover option | +| RTC1f | uts/test/realtime/unit/client/realtime_client.md | transportParams option | +| RTC2 | uts/test/realtime/unit/client/realtime_client.md | connection attribute | +| RTC3 | uts/test/realtime/unit/client/realtime_client.md | channels attribute | +| RTC4 | uts/test/realtime/unit/client/realtime_client.md | auth attribute | +| RTC12 | uts/test/realtime/unit/client/realtime_client.md | Constructor (same as REST) | +| RTC15 | uts/test/realtime/unit/client/realtime_client.md | connect() method | +| RTC16 | uts/test/realtime/unit/client/realtime_client.md | close() method | +| RTC17 | uts/test/realtime/unit/client/realtime_client.md | clientId attribute | + +### Types (T*) +| Spec | Test File | Description | +|------|-----------|-------------| +| TD | unit/types/token_types.md | TokenDetails | +| TK | unit/types/token_types.md | TokenParams | +| TE | unit/types/token_types.md | TokenRequest | +| TM | unit/types/message_types.md | Message | +| TO | unit/types/options_types.md | ClientOptions | +| AO | unit/types/options_types.md | AuthOptions | +| TI | unit/types/error_types.md | ErrorInfo | +| TG | unit/types/paginated_result.md | PaginatedResult | + +### Environment Configuration (REC) +| Spec | Test File | Description | +|------|-----------|-------------| +| REC1, REC2 | unit/client/fallback.md | Custom endpoints | + +## Pseudo-code Conventions + +### Setup Blocks +```pseudo +mock_http = MockHttpClient() +mock_http.queue_response(status, body) +mock_http.queue_response_for_host(host, status, body) + +client = Rest(options: ClientOptions(...)) +``` + +### Test Steps +```pseudo +result = AWAIT client.operation() +``` + +### Assertions +```pseudo +ASSERT condition +ASSERT value == expected +ASSERT value IN list +ASSERT value matches pattern "regex" +ASSERT value IS Type +ASSERT "key" IN object +ASSERT "key" NOT IN object +``` + +### Error Testing +```pseudo +TRY: + AWAIT operation_that_fails() + FAIL("Expected exception") +CATCH ExceptionType as e: + ASSERT e.code == expected_code +``` + +### Loops +```pseudo +FOR EACH item IN collection: + # test each item + +FOR i IN 1..10: + # test numbered items +``` + +### Polling +```pseudo +poll_until(condition, interval, timeout): + start = now() + WHILE now() -

+- Use mock HTTP client to verify request formation and response parsing +- Use mock WebSocket client for Realtime connection tests +- Test client-side validation and error handling +- Token strings are opaque - any arbitrary string works for unit tests +- No network calls - fast and deterministic + +### Integration Tests (Ably Sandbox) +- Run against `https://sandbox.realtime.ably-nonprod.net` +- Provision apps via `POST /apps` with body from `ably-common/test-resources/test-app-setup.json` +- Use `endpoint: "sandbox"` in ClientOptions + +## Mock Infrastructure Patterns + +### HTTP Mock Infrastructure + +**Reference the canonical specification:** +```markdown +## Mock HTTP Infrastructure + +See `uts/test/rest/unit/helpers/mock_http.md` for the full Mock HTTP Infrastructure specification. +``` + +**Key interfaces:** +```pseudo +interface MockHttpClient: + await_connection_attempt(timeout?: Duration): Future + await_request(timeout?: Duration): Future + reset() + +interface PendingConnection: + host: String + port: Int + tls: Boolean + respond_with_success() + respond_with_refused() + respond_with_timeout() + respond_with_dns_error() + +interface PendingRequest: + url: URL + method: String + headers: Map + body: Bytes + respond_with(status: Int, body: Any, headers?: Map) + respond_with_delay(delay: Duration, status: Int, body: Any) + respond_with_timeout() +``` + +### Handler-Based Pattern (Simple Tests) + +Use for tests with predetermined responses: + +```pseudo +captured_request = null + +mock_http = MockHttpClient( + onConnectionAttempt: (conn) => conn.respond_with_success(), + onRequest: (req) => { + captured_request = req + req.respond_with(200, {"time": 1234567890000}) + } +) +install_mock(mock_http) + +client = Rest(options: ClientOptions(key: "appId.keyId:keySecret")) +``` + +### Handler-Based with State (Complex Tests) + +Use for tests needing different responses based on request count or conditions: + +```pseudo +request_count = 0 +captured_requests = [] + +mock_http = MockHttpClient( + onConnectionAttempt: (conn) => conn.respond_with_success(), + onRequest: (req) => { + captured_requests.append(req) + request_count++ + IF request_count == 1: + req.respond_with(401, {"error": {"code": 40142}}) + ELSE: + req.respond_with(200, {"result": "success"}) + } +) +install_mock(mock_http) +``` + +### Await-Based Pattern (Advanced Control) + +Use when test needs to coordinate responses with test execution state. + +**Important:** The await pattern has a subtle timing requirement - when awaiting multiple sequential connection attempts, you must set up the await for the next attempt BEFORE responding to the current one: + +```pseudo +# Correct pattern for sequential awaits +first_conn = AWAIT mock_ws.await_connection_attempt() +second_future = mock_ws.await_connection_attempt() # Set up BEFORE responding +first_conn.respond_with_error(...) # This triggers retry +second_conn = AWAIT second_future +``` + +This avoids race conditions where the retry happens before the await is set up. + +### When to Use Each Pattern + +**Handler pattern** (recommended for most tests): +- Response is predetermined based on request count or content +- Simple "first attempt fails, second succeeds" scenarios +- No need to coordinate with external test state +- More universally safe across different language runtimes + +**Await pattern** (for advanced scenarios only): +- Need to inspect connection/request details before deciding how to respond +- Test logic depends on external state not known at setup time +- Complex coordination between multiple async operations + +Example using await pattern: + +```pseudo +mock_http = MockHttpClient() +install_mock(mock_http) + +client = Rest(options: ClientOptions(key: "...")) + +# Start operation +request_future = client.time() + +# Wait for and handle connection +connection = AWAIT mock_http.await_connection_attempt() +connection.respond_with_success() + +# Wait for and handle request +request = AWAIT mock_http.await_request() +ASSERT request.headers["X-Ably-Version"] IS NOT null +request.respond_with(200, {"time": 1234567890000}) + +# Complete operation +result = AWAIT request_future +``` + +### WebSocket Mock Infrastructure + +For Realtime tests, reference the WebSocket mock: + +```markdown +## Mock WebSocket Infrastructure + +See `uts/test/realtime/unit/helpers/mock_websocket.md` for the full Mock WebSocket Infrastructure specification. +``` + +**Key interfaces:** +```pseudo +interface MockWebSocket: + events: List # Unified timeline + await_connection_attempt(timeout?: Duration): Future + await_request(timeout?: Duration): Future + send_to_client(message: ProtocolMessage) + send_to_client_and_close(message: ProtocolMessage) # Send then close + simulate_disconnect() # Close without message + reset() + +interface PendingConnection: + host: String + port: Int + tls: Boolean + respond_with_success() + respond_with_refused() + respond_with_timeout() + respond_with_dns_error() +``` + +### WebSocket Connection Closing Semantics + +When simulating server behavior, use the correct method based on the scenario: + +| Scenario | Method | Description | +|----------|--------|-------------| +| Server sends DISCONNECTED | `send_to_client_and_close()` | Server

(channel-level) | `send_to_client()` | ERROR with channel = attachment failure, connection stays open | +| Server sends CONNECTED, HEARTBEAT, ACK, MESSAGE | `send_to_client()` | Normal messages, connection stays open | +| Unexpected transport failure | `simulate_disconnect()` | Connection drops without server message | + +**Key rule:** Whenever the server sends DISCONNECTED, or ERROR without a specified channel, it will be accompanied by the server closing the WebSocket connection.
