Testing your Sync Gateway functions with synctos

Joel Andrews, a versatile developer based in Canada's west coast, elaborates on using synctos, an open-source tool developed by Kashoo to streamline the creation of sync functions for Couchbase Sync Gateway. In his post, Andrews introduces the tool's built-in test-helper module, which aids in writing tests that validate document definitions, underscoring the importance of testing code for bugs. He provides a detailed walkthrough on setting up a Node.js project with necessary dependencies like expect.js, mocha, and simple-mock, and explains the process of creating a simple document definition as a demonstration. Andrews guides readers through generating a sync function using synctos, setting up test cases to validate document constraints, and running tests to ensure accuracy. He encourages exploring the test-helper module's documentation for advanced testing capabilities and directs readers to GitHub for source code access.
