That report is fed directly into Cursor, which writes and pushes a fix, after which Manus re-tests the deployment and confirms the bugs are resolved. The presenter argues this shows an end-to-end AI-driven test cycle but warns of the risk of letting an AI validate its own fixes, suggesting isolated multi-agent systems as a better practice, and points to their annual state of test automation survey. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### Can an AI agent like Manus find and verify bugs on a website without any human-written test scripts? Yes, Manus was able to autonomously spider a website's DOM with no page object model, sitemap, or swagger doc, discover a hard 404 on a primary call-to-action button, generate a structured bug report with reproducible steps, and later re-run regression tests to confirm a fix worked, all without custom automation code. _daily.dev surfaces AI agent experiments like this for developers evaluating autonomous QA workflows._ ### Is it safe to let the same AI system both fix bugs and verify that the fix worked? It carries risk because the AI is effectively grading its own homework, so a fix could appear verified even when it is not. A recommended best practice is running a multi-agent setup where the agent writing the code is completely isolated from the agent testing the code, rather than relying on one closed loop. _developers weighing AI agent trust boundaries can track this kind of guidance on daily.dev._ ## Similar posts on daily.dev -
