From 1cfbdc3bdf083938197eb4dedb98106a912caa1c Mon Sep 17 00:00:00 2001 From: czlonkowski <56956555+czlonkowski@users.noreply.github.com> Date: Sat, 4 Oct 2025 23:33:10 +0200 Subject: [PATCH 1/3] feat: implement Phase 5 integration tests (workflow management) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implemented comprehensive integration tests for workflow deletion and listing: Test Coverage (16 scenarios): - delete-workflow.test.ts: 3 tests * Successful deletion * Error handling for non-existent workflows * Cleanup verification - list-workflows.test.ts: 13 tests * No filters (all workflows) * Filter by active status (true/false) * Filter verification * Pagination (first page, cursor, last page) * Limit variations (1, 50, 100) * Exclude pinned data * Empty results * Sort order verification Critical Fixes: - handleDeleteWorkflow: Now returns deleted workflow data (per n8n API spec) - handleListWorkflows: Convert tags array to comma-separated string (n8n API format) - N8nApiClient.deleteWorkflow: Return Workflow object instead of void - WorkflowListParams.tags: Changed from string[] to string (API expects CSV format) All 71 integration tests passing. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- src/mcp/handlers-n8n-manager.ts | 16 +- src/services/n8n-api-client.ts | 5 +- src/types/n8n-api.ts | 2 +- .../n8n-api/workflows/delete-workflow.test.ts | 132 ++++++ .../n8n-api/workflows/list-workflows.test.ts | 438 ++++++++++++++++++ 5 files changed, 585 insertions(+), 8 deletions(-) create mode 100644 tests/integration/n8n-api/workflows/delete-workflow.test.ts create mode 100644 tests/integration/n8n-api/workflows/list-workflows.test.ts diff --git a/src/mcp/handlers-n8n-manager.ts b/src/mcp/handlers-n8n-manager.ts index 874d869..8e0cf2f 100644 --- a/src/mcp/handlers-n8n-manager.ts +++ b/src/mcp/handlers-n8n-manager.ts @@ -607,11 +607,12 @@ export async function handleDeleteWorkflow(args: unknown, context?: InstanceCont try { const client = ensureApiConfigured(context);
