Reusable Sub-workflow Testing in n8n

This n8n workflow demonstrates a modular approach to building and testing sub-workflows independently. It allows users to set up a reusable sub-workflow that can accept inputs from parent workflows or be tested in isolation. The workflow begins with a manual trigger for local testing, where a sample input (like ‘blue’) is defined. This input is combined with information received from another workflow trigger node, enabling dynamic data integration. A conditional ‘If’ node then evaluates the input data, such as checking if a color equals ‘blue’, to trigger subsequent actions or workflows accordingly. This setup is ideal for developers aiming to create maintainable, testable automations that can be integrated or tested separately from larger processes. Practical use cases include testing sub-logic modules before deployment, ensuring robustness and reusability in complex workflows, and providing a clear structure for input handling and condition evaluation.
