Test Suite

Functional and integration tests that verify correctness of every layer — from raw io_uring events up to full GObj protocol stacks. All tests are registered as ctest targets and run automatically with yunetas test.

Source: tests/c/

# Run the full suite
yunetas test

# Run a single test by name
ctest -R test_c_timer --output-on-failure --test-dir build

# Run ctest in a loop until first failure (flaky-test detection)
./ctest-loop.sh

Event loop (yev_loop)¶

Low-level tests for the io_uring event loop, without the GObj layer.

Binary	Description
`test_yevent_listen1–4`	Server creates a listen socket and accepts one client connection.
`test_yevent_connect1–2`	Client connects to a listening server; verifies the connection succeeds.
`test_yevent_traffic1–6`	Client ↔ server message echo over plain TCP (multiple variants).
`test_yevent_udp_traffic1`	UDP message echo.
`test_yevent_traffic_secure1`	TLS-encrypted TCP message echo.
`test_yevent_timer_once1–2`	One-shot timer expiration.
`test_yevent_timer_periodic1`	Periodic (recurring) timer.

Timers¶

Binary	Description
`test_c_timer`	`C_TIMER` GClass — periodic timeout operations.
`test_c_timer0`	`C_TIMER0` GClass — basic (low-level) timer.

Source: tests/c/c_timer/, tests/c/c_timer0/

TCP networking¶

Plain and TLS TCP through the full GObj protocol stack.

Binary	Description
`test_c_tcp test1–4`	Plain TCP: connect, disconnect, echo, and rapid multi-message burst.
`test_c_tcp2 test1–4`	Same scenarios using the newer `C_TCP_S` method (no `child_tree_filter`).
`test_c_tcps test1–4`	TLS TCP: connect, disconnect, echo, and multi-message burst.
`test_c_tcps2 test1–4`	TLS TCP with the newer method.

TLS certificate hot-reload¶

Protects the cert-reload feature — validates that ytls_reload_certificates() swaps certificates atomically without dropping live sessions and rolls back cleanly on invalid material.

Binary	Description
`test_cert_reload`	Swap cert A → B and confirm `view-cert` reflects the new subject/not_after; feed an invalid cert and verify the previous context is kept intact (rollback).
`test_cert_info`	`ytls_get_cert_info()` edge cases: short / long validity, self-signed invariant, serial shape, client-side `NULL`, already-expired cert.
`test_cert_reload_mem`	1000 reloads without any live session and asserts `get_cur_system_memory() == 0` (leak gate, run under valgrind for exhaustive checking).
`test_yevent_reload_live`	One reload while a TCP session is live; the session keeps working end-to-end.
`test_yevent_reload_stress`	50 reloads with a live session, one echo message per iteration.

Source: tests/c/ytls/, tests/c/yev_loop/yev_events_tls/

HTTP parser (llhttp wrapper)¶

Binary	Description
`test_c_llhttp_parser`	Sanity test for the vendored llhttp library and the `ghttp_parser` wrapper: request/response parse, keep-alive pipelining, `HPE_PAUSED_UPGRADE` tail bytes, EOF completion via `ghttp_parser_finish()`.

Source: tests/c/c_llhttp_parser/

OAuth2 / BFF (c_auth_bff)¶

Self-contained yunos that spin up a mock Keycloak (signed HS256 JWTs, scriptable latency / response status / body override) alongside C_AUTH_BFF and drive /auth/login, /auth/callback, /auth/refresh, /auth/logout through happy paths and failure modes. Each test is its own binary so a crash or leak cannot mask neighbours.

Binary	Description
`test1_login`	Happy-path login round-trip through the BFF.
`test2_kc_401`	IdP returns 401; BFF must surface a stable `error_code` and not poison its `kc_ok` counter.
`test3_callback`	`/auth/callback` code-for-token exchange.
`test4_refresh`	Proactive refresh-token round-trip.
`test5_logout`	Logout clears cookies and drives the IdP revoke endpoint.
`test6_invalid_body`	Malformed JSON body → 4xx with `error_code` mapped for the GUI.
`test7_slow_login`	IdP replies slowly; the BFF keeps the browser waiting without timing out early.
`test8_queue_full`	Pipeline 4 POSTs + overflow: `dl_list` pending queue drops the overflow in order and reports the configured `pending_queue_size`.
`test9_browser_cancel`	Browser disconnects mid-round-trip; the BFF drops the stale IdP reply (`responses_dropped` counter) instead of forwarding it.
`test10_kc_silence`	IdP goes totally silent; `kc_timeout_ms` watchdog fires, responds 504 to the browser and drains the task (`kc_timeouts` counter).
`test11_cancel_retry`	Cancel-then-retry: state cleanup between two back-to-back logins on the same browser.
`test12_stale_reply`	Per-task browser generation blocks cross-user token leak races.
`test13_refresh_expired`	Expired refresh token → mapped error, no silent `kc_error`.
`test14_method_not_allowed`	Non-POST on an auth endpoint → 405.
`test15_missing_body`	Missing body → 4xx with mapped error.
`test16_unknown_endpoint`	Unknown `/auth/*` path → 404, not 5xx.

MQTT¶

Binary	Description
`test_c_mqtt test1`	Self-contained broker + client: subscribe, publish QoS 0, verify reception, disconnect.

Source: tests/c/c_mqtt/

Subscriptions & link events¶

Binary	Description
`test_subscriptions test1–2`	GObj event subscribe / unsubscribe lifecycle.
`test_c_node_link_events`	`EV_TREEDB_NODE_LINKED` / `UNLINKED` events at the `C_NODE` GClass level.
`test_tr_treedb_link_events`	Low-level link/unlink callback mechanism in `tr_treedb`.

Timeranger2 persistence¶

Binary	Description
`test_tranger_startup`	Database initialization and startup.

`test_topic_pkey_integer_iterator2`	Iterator with per-key callbacks and time-based matching.
`test_topic_pkey_integer_iterator3`	Absolute-position searches.
`test_topic_pkey_integer_iterator4`	Relative-position searches.
`test_topic_pkey_integer_iterator5`	Paginated searches.
`test_topic_pkey_integer_iterator6`	Master/client iterator mode with realtime record additions.
`test_testing`	Testing utilities (event counters, assertions).

TR_MSG & TR_QUEUE¶

Binary	Description
`test_tr_msg1`	Message topics: iteration, key matching, instance retrieval.
`test_tr_msg2`	Stress variant: 1 000 devices × 100 traces.
`test_tr_queue1`	Queue topic: enqueue / dequeue with time-based keys over a multi-day period.

TreeDB¶

Binary	Description
`test_tr_treedb`	Schema creation, user/department/compound structures, node CRUD, and state snapshots (foto files).

Source: tests/c/tr_treedb/

Keyword matching¶

Binary	Description
`test_kw1`	`kw_match_simple()` with strings, booleans, integers, and floats.

Source: tests/c/kw/

Generic message interchange¶

A JSON-driven test runner that executes scripted test sequences and validates event traces and error logs.

Test scenario	Description
`test_mqtt_qos0`	MQTT QoS 0 publish/subscribe interchange.
`test_tcp_connect`	TCP connection establishment.
`test_tcp_reconnect`	TCP reconnection and recovery.

Source: tests/c/msg_interchange/

Build flag¶

Tests are enabled by default via .config (CONFIG_MODULE_TEST=y). Toggle with menuconfig or pass -DENABLE_TESTS=OFF to CMake.

Performance benchmarks live under performance/c/ — perf_c_tcp, perf_c_tcps, perf_yev_ping_pong, perf_yev_ping_pong2 and the new perf_auth_bff (ping-pong-style live throughput over the BFF; default 10 s runs, ~180 000 ops on the reference box).
Stress runners live under stress/c/ — stress/auth_bff drives concurrent BFF login / refresh / logout cycles to expose races between the pending queue, the watchdog and the flush-on-disconnect path.
