N8n Node Testing

About

This skill equips developers with the standards and patterns necessary for building robust n8n nodes through rigorous automated and manual testing. It provides specialized guidance on mocking API interactions with nock, creating execution contexts for node tests, and validating complex outputs with golden file comparisons. By following these established workflows, developers can ensure their nodes handle error states gracefully, pass all linting requirements, and integrate seamlessly with the n8n UI before publishing to the community.

Key Features

• Mocking of IExecuteFunctions for node execution validation
• 0 GitHub stars
