Node Testing Now Requires Re-running Entire Workflow

Hi n8n team,

I have been using n8n since October 2024 and I absolutely love how much the platform has grown. That said, I want to highlight an issue I recently encountered.

In the past, it was possible to test a single node without having to re-run the entire workflow. After the latest update, it seems we now need to execute the whole workflow just to test one node.

I understand that we still have the option to pin data, but even then the change impacts efficiency. Debugging becomes slower and iteration cycles take longer, which is especially frustrating when working on larger or more complex workflows. On top of that, this approach is also significantly more costly when LLMs or other paid APIs are part of the workflow, since we end up re-running calls unnecessarily.

Can you please confirm if this is an intentional update or a bug? From my experience, the ability to test nodes individually is a critical feature and an essential part of building and scaling workflows effectively.

Thanks for your time and for all the great work on n8n.
