# Testing Your App Against Device Disconnection and Removal

> Learn how to use the Seam suite of simulate endpoints to test your app against events that are difficult to orchestrate in your quality assurance environment.

When developing an app to control IoT devices—before moving to production—it is imperative to test your app against events like device disconnection and removal. However, it can be difficult to orchestrate these events in your quality assurance (QA) environment using real devices. To help you test your app more easily and effectively, Seam provides the following suite of `simulate` endpoints that you can use in a [sandbox workspace](/core-concepts/workspaces/index#sandbox-workspaces):

* [`/devices/simulate/disconnect`](#simulate-disconnecting-a-device)
* [`/devices/simulate/connect`](#simulate-connecting-a-device)
* [`/devices/simulate/remove`](#simulate-removing-a-device)

<Info>
  Currently, Seam supports these endpoints for
  [August](/device-and-system-integration-guides/august-locks/august-locks-sample-data)
  and
  [Yale](/device-and-system-integration-guides/yale-locks/yale-sample-data)
  sandbox devices.

## Simulation Capability Flags

The Seam API provides the following sandbox-only [capability flags](../../capability-guides/device-and-system-capabilities#capability-flags) that show you which simulate endpoints you can currently use on a device:

* `device.can_simulate_disconnection`
* `device.can_simulate_connection`
* `device.can_simulate_removal`

## Simulate Disconnecting a Device

To simulate a device disconnection:

**Code:**

<CodeGroup>
  ```javascript JavaScript theme={null}
  // Get the device.
  const device = await seam.devices.get({
    device_id: '11111111-1111-1111-1111-444444444444',
  })

  // Confirm that Seam supports simulated disconnection for the device.
  if (device.can_simulate_disconnection) {
    // Perform the simulated disconnection.
    await seam.devices.simulate.disconnect({
      device_id: device.device_id,
    })
  }
  ```

  ```bash cURL theme={null}
  # Get the device.
  device=$(
    # Use GET or POST.
    curl -X 'GET' \
      'https://connect.getseam.com/devices/get' \
      -H 'accept: application/json' \
      -H "Authorization: Bearer ${SEAM_API_KEY}" \
      -H 'Content-Type: application/json' \
      -d '{
        "device_id": "11111111-1111-1111-1111-444444444444"
    }')

  # Confirm that Seam supports simulated disconnection for the device.
  if  $(jq -r '.device.can_simulate_disconnection' <<< ${device}); then \
    # Perform the simulated disconnection.
    curl -X 'POST' \
      'https://connect.getseam.com/devices/simulate/disconnect' \
      -H 'accept: application/json' \
      -H "Authorization: Bearer ${SEAM_API_KEY}" \
      -H 'Content-Type: application/json' \
      -d "{

    }";
  fi
  ```

    device_id="11111111-1111-1111-1111-444444444444"
  )

  # Confirm that Seam supports simulated disconnection for the device.
  if device.can_simulate_disconnection:
    # Perform the simulated disconnection.
    seam.devices.simulate.disconnect(device_id=device.device_id)
  ```

  # Confirm that Seam supports simulated disconnection for the device.
  if (device.can_simulate_disconnection)
    # Perform the simulated disconnection.
    client.devices.simulate.disconnect(device_id: device.device_id)
  end
  ```

  ```php PHP theme={null}
  // Get the device.
  $device = $seam->devices->get(device_id: "11111111-1111-1111-1111-444444444444");

  // Confirm that Seam supports simulated disconnection for the device.
  if ($device->can_simulate_disconnection) {
    // Perform the simulated disconnection.
    $seam->devices->simulate->disconnect(device_id: $device->device_id);
  }
  ```

  ```csharp C# theme={null}
  // Get the device.
  Device device = seam.Devices.Get(deviceId: "11111111-1111-1111-1111-444444444444");

  // Confirm that Seam supports simulated disconnection for the device.
  if (device.CanSimulateDisconnection == true) {
    // Perform the simulated disconnection.
    seam.Devices.Simulate.Disconnect(deviceId: device.DeviceId);
  }
  ```
</CodeGroup>

**Output:**

<CodeGroup>
  ```json JavaScript theme={null}

  ```

  ```json cURL theme={null}

## Simulate Device Disconnection, Connection, and Removal in the Seam Console

You can also use the [Seam Console](https://console.seam.co/) to simulate disconnecting, connecting, and removing a device.

<Info>
  Currently, Seam supports these actions for
  [August](/device-and-system-integration-guides/august-locks/august-locks-sample-data)
  and
  [Yale](/device-and-system-integration-guides/yale-locks/yale-sample-data)
  sandbox devices.
</Info>

1. In the upper-right corner of the Seam Console, click the down arrow to display the workspace list and select a sandbox workspace.
2. In the left navigation pane of the Seam Console, click **Connected Accounts**.
3. Click the account that contains the device that you want to simulate disconnecting, connecting, or removing.
4. At the right of the row for the desired device, click **...** and select **Simulate Removal**, **Simulate Connection**, or **Simulate Disconnection**.\
   The Seam Console only displays the actions that you can perform based on the current state of the device. For example, if the device is already disconnected, you cannot simulate disconnection.
5. Click **Simulate Removal**, **Simulate Connection**, or **Simulate Disconnection** to confirm the action.
