According to best practices, when should you test your process model?

Testing your process model after configuring the entire model aligns with best practices in process development. This approach allows you to evaluate the functionality, flow, and integration of all components of the process together, ensuring that they work cohesively as intended. By waiting until the entire model is configured, you can identify issues that may arise from the interaction of various elements, including tasks, rules, and decision points, which may not be apparent if tested in isolation.

Also, this method helps to validate the overall design before deployment, ensuring that all aspects of the model function together correctly. While it is essential to test after significant modifications during the development cycle, comprehensive testing at the end ensures that the entire process meets business requirements and expectations, ultimately leading to a more robust and efficient outcome.
