From addeeeb1a49b33bcde26a86b21cc568044ab393b Mon Sep 17 00:00:00 2001 From: shrimbly Date: Tue, 13 Jan 2026 21:06:40 +1300 Subject: [PATCH] test(20-01): add topological sort integration tests - Execution order (linear chain, multiple dependencies, parallel branches) - Cycle detection - Pause edge handling (stop, resume, pausedAtNodeId) - Locked group handling (skip locked, execute unlocked) - Start from specific node - Execution state management Co-Authored-By: Claude Opus 4.5 --- .../workflowStore.integration.test.ts | 411 ++++++++++++++++++ 1 file changed, 411 insertions(+) diff --git a/src/store/__tests__/workflowStore.integration.test.ts b/src/store/__tests__/workflowStore.integration.test.ts index d10de6ab..94eec8e3 100644 --- a/src/store/__tests__/workflowStore.integration.test.ts +++ b/src/store/__tests__/workflowStore.integration.test.ts @@ -705,4 +705,415 @@ describe("workflowStore integration tests", () => { });
