From 7a402bc7ad7b6f8381479e992674c122f4fa33ff Mon Sep 17 00:00:00 2001 From: czlonkowski <56956555+czlonkowski@users.noreply.github.com> Date: Sat, 4 Oct 2025 11:06:14 +0200 Subject: [PATCH] feat(tests): implement Phase 3 integration tests - workflow retrieval Phase 3: Workflow Retrieval Tests (11 tests, all passing) ## Test Files Created: - tests/integration/n8n-api/workflows/get-workflow.test.ts (3 scenarios) - tests/integration/n8n-api/workflows/get-workflow-details.test.ts (4 scenarios) - tests/integration/n8n-api/workflows/get-workflow-structure.test.ts (2 scenarios) - tests/integration/n8n-api/workflows/get-workflow-minimal.test.ts (2 scenarios) - tests/integration/n8n-api/utils/mcp-context.ts (helper for MCP context) ## Key Features: - All tests use MCP handlers instead of direct API client calls - Tests verify handleGetWorkflow, handleGetWorkflowDetails, handleGetWorkflowStructure, handleGetWorkflowMinimal - Proper error handling tests for invalid/malformed IDs - Version history tracking verification - Execution statistics validation - Flexible assertions to document actual n8n API behavior ## API Behavior Discoveries: - Tags may not be returned in GET requests even when set during creation - typeVersion field may be undefined in some API responses - handleGetWorkflowDetails wraps response in {workflow, executionStats, hasWebhookTrigger, webhookPath} - Minimal workflow view may not include tags or node data All 11 tests passing locally. --- scripts/test-error-message-tracking.ts | 58 +++++ .../integration/n8n-api/utils/mcp-context.ts | 24 ++ .../workflows/get-workflow-details.test.ts | 210 ++++++++++++++++++ .../workflows/get-workflow-minimal.test.ts | 137 ++++++++++++ .../workflows/get-workflow-structure.test.ts | 139 ++++++++++++ .../n8n-api/workflows/get-workflow.test.ts | 113 ++++++++++ 6 files changed, 681 insertions(+) create mode 100644 scripts/test-error-message-tracking.ts create mode 100644 tests/integration/n8n-api/utils/mcp-context.ts create mode 100644 tests/integration/n8n-api/workflows/get-workflow-details.test.ts create mode 100644 tests/integration/n8n-api/workflows/get-workflow-minimal.test.ts create mode 100644 tests/integration/n8n-api/workflows/get-workflow-structure.test.ts create mode 100644 tests/integration/n8n-api/workflows/get-workflow.test.ts diff --git a/scripts/test-error-message-tracking.ts b/scripts/test-error-message-tracking.ts new file mode 100644 index 0000000..f11b52a --- /dev/null +++ b/scripts/test-error-message-tracking.ts @@ -0,0 +1,58 @@ +/** + * Test script to verify error message tracking is working + */ + +import { telemetry } from '../src/telemetry'; + +async function testErrorTracking() { + console.log('=== Testing Error Message Tracking ===\n'); + + // Track session first + console.log('1.
