# How to test each step in the Flow?

Testing each step in the Flow involves validating each component’s functionality to ensure it operates as expected. Once a component is tested, you will be provided with sample data. The generated sample data can then be used to validate and refine subsequent steps, contributing to the overall development and reliability of your Flow application.

Here is how to test each step:

1. Select the component you wish to test. In this case, we are selecting the second component of the Flow, labeled as ‘Ask LLM’.

4. The sample data will be generated successfully. Repeat the same step to test each component.
