Add unit tests + cross-repo integration CI job (#4)

zspitzer · web-flow · commit 0507d0c381b5 · 2026-04-18T01:14:37.000+02:00
* add behavioural unit tests and cross-repo integration CI job

* convert unit tests to BDD style and drop compile-time arity tests

* fix RecordingListener onError signature to match 2-arg invocation

* improve onError test failure message to diagnose why events are empty or wrong

* drop onError-on-sync-connect test — nv-websocket-client throws without invoking listener in that path

* warm up extension before integration tests to avoid 404 race on first connect

+# WebSocket Client Extension — Tests
+
+## Two test tiers
+
+### Unit tests (this folder)
+
+`WebSocketClientTest.cfc` extends `org.lucee.cfml.test.LuceeTestCase` and exercises the BIF's own contract — no WebSocket server required:
+
+- `CreateWebSocketClient()` argument validation (arg counts, non-component listener)
+- Scheme handling (`ws://`, `wss://`, rejection of `http://`)
+- Connection error timing (refused-connection fails fast, unroutable IP hits the library's 5s timeout)
+- `onError( type="connect", ... )` listener invocation on connect failure
+- OSGi loader health
+
+Runs in the `test` job via `lucee/script-runner@main` with `testLabels: websocketclient`. Fast, no network dependencies beyond loopback.
+
+### Integration tests (server repo)
+
+The real client⇄server coverage — `sendText`, `sendBinary`, `onMessage`, `onClose`, `disconnect`, `isOpen`, lifecycle event ordering — lives in the server extension repo:
+
+[lucee/extension-websocket — `tests/integration/`](https://github.com/lucee/extension-websocket/tree/master/tests/integration)
+
+Those tests use `CreateWebSocketClient` as the driver against a Lucee WebSocket server listener, so they cover both extensions end to end.
+
+## Why not duplicate the integration tests here?
+
+Every integration test needs both extensions running. Duplicating the suite across two repos guarantees drift. Instead:
+
+- One copy lives in the server repo.
+- The `test-integration` job in this repo's workflow **sparse-checkouts** `tests/integration/` from the server repo, builds this branch's client `.lex`, pulls the latest server `.lex` from download.lucee.org, and runs the suite against the combined pair.
+- Each side's CI catches the bug on its own side — server changes fail in the server repo, client changes fail here.
+
+## What fails where
+
+| Bug source | Caught by |
+| --- | --- |
+| Client BIF contract (scheme handling, error shape, connection timing) | Unit tests in this repo |
+| Client send/receive, lifecycle, reconnect | Integration tests (cross-repo) |
+| Server callback firing, broadcast, state | Integration tests (server repo CI) |
+
+## Adding a test
+
+Needs a server to drive it? **Add it to the server repo's [`tests/integration/`](https://github.com/lucee/extension-websocket/tree/master/tests/integration).** Both CIs will pick it up.
+
+No server needed (argument validation, error shape, scheme parsing)? **Add a `testXxx()` method to [`WebSocketClientTest.cfc`](WebSocketClientTest.cfc) here.**
+
+## Running locally
+
+Unit tests — whatever CFML test runner you use that picks up `labels="websocketclient"`. Or invoke `WebSocketClientTest.cfc` methods directly from a test script.
+
+Integration tests — spin up Lucee with both extensions, drop the server listeners into `{lucee-config}/websockets/`, and `curl` the `.cfm` scripts from the server repo's `tests/integration/` folder. See [that repo's CI workflow](https://github.com/lucee/extension-websocket/blob/master/.github/workflows/main.yml) for the exact setup — it's the same one this repo's `test-integration` job uses.
