From 905fdc780a1f3823a0f0e02ec6f40bfdb1922d76 Mon Sep 17 00:00:00 2001 From: gamer147 Date: Sun, 31 May 2026 23:37:31 -0400 Subject: [PATCH] test(battle-node): end-to-end flow test through Ready via WebApplicationFactory MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Boots SVSimTestFactory (in-memory SQLite + reference-data CSV import), mints a battle via IMatchingBridge, opens a raw Socket.IO v2 client against the in-process TestServer, drives InitNetwork → Loaded → Swap, and asserts the right scripted frames come back in order. Verifies the full transport stack end-to-end: EIO3+SIO2 framing, encryptForNode codec, MsgPayloadCodec roundtrip, InboundTracker pubSeq dedup + ack echo, OutboundSequencer playSeq assignment, and ScriptedLifecycle's Path-A frame builders. Note: RawSocketIoTestClient.DisposeAsync skips the graceful CloseAsync handshake — TestServer's in-process WebSocket implementation can hang on it. Abrupt Dispose is fine: the server's ReceiveAsync throws WebSocketException, BattleSession.RunAsync returns, and the handler completes.
