## Overview

The Test Panel lets you test a workflow run in real time before turning it on. Perfect for:

* **Testing workflows**: Run a workflow step-by-step to see exactly what happens
* **Debugging issues**: Identify problems in your logic or configuration
* **Validating triggers**: Test different trigger scenarios and inputs

## How to Use the Test Panel

1. **Open the Test Panel**: Click the test button in the top right corner of your workflow editor

2. **Select Your Trigger**
   * A right panel will appear where you can choose from available triggers
   * If you have multiple triggers, you'll see multiple trigger options to start from
   * Click the trigger you want to test

3. **Run and Monitor**
   * Your workflow will execute step-by-step
   * Watch each action happen in real-time
   * See outputs, errors, and decision points
   * Follow the complete workflow from start to finish

<Tip>
  The first 500 credits per test run are free! This gives you plenty of credits to thoroughly test your workflows before going live.

## Important Notes

<AccordionGroup>
  <Accordion title="Real-time Testing">
    The test panel shows actual execution - not a simulation. Actions will really run, APIs will be called, and data will be processed. Use test data when possible.
  </Accordion>

  <Accordion title="Google Sheets Testing">
    When testing Google Sheets, it can sometimes take a minute for new rows to populate in the test panel. Be patient - this is because of the Google API.
