With the LangChain Open Canvas, we can create manual test cases directly from requirements using gen AI. This feature creates a list of manual test cases by analyzing Workato recipe JSON code. From there, you can either refine the initial list or provide detailed instructions to produce test cases customized to your specific requirements, streamlining your testing process and ensuring the reliability of your Workato recipes.

To accomplish this, we’ll need to modify the Open Canvas codebase to include an option for generating test cases at the Workato recipe level.

Let’s understand the below process to generate the cases.
