# Test a workflow

> Try the Canvas with real input and inspect each step before you publish it.

Click **Test run** in Studio’s top-right controls to open the test panel. You can test the graph while it’s still on Canvas.

![Test run beside Canvas with the session limit, coordinator, input and dry-run switch](https://mintcdn.com/frswdefsf/RpCjAbmgwslrQ5q4/images/test-run.png?fit=max\&auto=format\&n=RpCjAbmgwslrQ5q4\&q=85\&s=cc37281667ca88965d72c21e6461b330)

**1. Choose the session and coordinator**

Check the spending limit and select the coordinator for this test. Use [Session](https://docs.man0.space/app/session.md) if you need to approve funds.

**2. Add your input**

Type the task, attach a file, or record a voice message. Files can be up to 20 MB each. Preview a recording before sending it.

**3. Choose how to test**

**Dry run (no external paid actions)** starts selected. It tests without connector writes; models and read operations can still use paid compute. Clear it when you want the connector to carry out the action.

**4. Review the outputs**

Submit the input, follow the activity, then open the individual step outputs. If the workflow asks for information or a connection, supply it and continue the same thread.

Press **Enter** to submit or **Shift + Enter** for a new line. After the test, edit any unclear step instructions and [save the draft](https://docs.man0.space/app/canvas.md#save-the-workflow).
