Building a 12-Case Test Suite for a 10-Agent SEO System

We built an automated test suite covering every SEO sub-agent, discovered keyword rankings were entirely fake due to a missing OAuth2 credential, and shipped a live n8n execution log panel into the dashboard settings page.

Our SEO system runs 10 sub-agents: technical crawler, analytics, keyword research, GEO, AEO/FAQ, competitive intelligence, content strategist, content optimizer, pipeline, and link building. Each one writes findings to a shared seo_findings table. Until this week, we had zero automated coverage of any of them.

Defining the Test Cases

We started by screenshotting the SEO dashboard and mapping every visible feature to test cases.TC-SEO-01 through TC-SEO-12.

Why We Moved IMAP Out of n8n and Into a Next.js API Route

n8n's emailReadImap node was crash-looping our Hostinger connection. We fixed it by moving all IMAP reading into a Next.js endpoint using imapflow, then calling it from n8n via HTTP Request. 72 emails processed on the first clean run.
