This page provides information about workflow simulations and how to
run them.

Running simulations can help you identify and resolve issues with your workflow
before making it live. Simulations can also help you understand how your
workflow will behave in different situations.

## Run a simulation

### App

To run a simulation of your workflow, do the following:

1. Open your Gemini Enterprise web app in a browser.
2. In the web app navigation menu, click ![Agents
   icon](https://docs.cloud.google.com/static/gemini/enterprise/docs/workflow-builder/images/button_magic_icon.png) **Agents**.
3. The **Agent Gallery** page appears displaying all the prebuilt available agents and workflows in your web app.
4. Go to the **Your agents** section and
   click the workflow that you want to simulate.

   The workflow canvas appears.
5. Go to the **Preview** tab and click **Start simulation**.

6. A simulation of the workflow begins. You can interact with the
   simulation in the same way that you would interact with the live
   workflow (for example, by providing inputs or answering
   questions).

7. When the simulation ends, a summary of the simulation results appears.
   Expand the summary to see details about the simulation, such as the
   individual steps that the workflow took, the actions and reasoning that
   the workflow performed at each step, and the outputs of each step.
