Automating Multiple Devices

This tutorial shows how to automate multiple devices on the same network by using AskUI. After following this page, you will be able to automate more than one device across different platforms, whether Linux, macOS, Windows or Android.

📌 The following tutorial assumes that you have already installed and set up the AskUI library on your local device. The code for the configuration is based on the generated code. See Getting Started for more details.

Automate Remote Devices Running on Windows, Linux or macOS​

1. Download and Prepare the AskUI Controller Binary for Each Device​

Download the binary for the respective platform and install it on the device(s) you want to automate remotely:

Windows - Please use the AskUI Installer from our Getting Started

2. Run the Controller on Each Device​

Run the AskUI Controller on the remote devices with the following command:

# Activate AskUI Development Environment (ADE) first
AskUI-StartController -DisplayNum 0 -Port 6769

If running successfully, you should see the logs printed on the terminal, for example:

[2023-01-02 17:31:19.634 +0100] DEBUG (AskuiUiController): Window is minimized.
[2023-01-02 17:31:19.639 +0100] INFO (AskuiUiController): Selecting display number 0.
[2023-01-02 17:31:19.641 +0100] INFO (AskuiUiController): Successfully started.

3. Configure the askui-helper.ts​

Figure out the local IP address of the remote device(s), and then change the <ip-address-remote-device*> in the askui-helper.ts:

import { UiControlClient, UiController } from 'askui';

let remoteDevice1: UiControlClient;
let remoteDevice2: UiControlClient;

jest.setTimeout(60 * 1000 * 60);

beforeAll(async () => {

    // Get your AskUI credentials from https://app.askui.com/workspaces
    const credentials = {
        workspaceId: '<your-workspace-id>',
        token: '<your-token>',
    }

    // This client will communicate with
    // the controller running on the remote device 1.
    // Replace the <ip-address-remote-device1>
    // with the IP from remote device 1
    remoteDevice1 = await UiControlClient.build({ 
        uiControllerUrl: "ws://<ip-address-remote-device2>:6769",
        credentials,
    });

    await remoteDevice1.connect();

    // This client will communicate with
    // the controller running on the remote device 2.
    // Replace the <ip-address-remote-device2>
    // with the IP from remote device 2
    remoteDevice2 = await UiControlClient.build({    
        uiControllerUrl: "ws://<ip-address-remote-device2>:6769", 
        credentials,
    });

    await remoteDevice2.connect();

    // Add more UiControlClients for more devices
});

afterAll(async () => {
    remoteDevice1.close();
    remoteDevice2.close();
});

export { remoteDevice1, remoteDevice2 };

Automate Remote Device(s) Running on Android​

info

Automating a remote Android device works differently than automating a Windows, Linux or macOS remote device. Your local machine communicates with the remote Android device over the Android Debug Bridge.

Thus the AskUI Controller runs on your local machine and not on the remote Android device!

Also check out our example repository to see the setup in action 🙂.

1. Prepare Your Android Device(s)​

Prepare your remote Android device(s) with this tutorial.

Use the commands below, if you want to connect an Android device via adb wirelessly:

# Connect the Android device with a
# USB cable, and run this command:

# Run this command to confirm that your
# Android device is discoverable
adb devices # will print the <device-id>

# Replace <device-id> with your device-id
# This sets the port the adb is listening
# on for commands.
#
# IMPORTANT:
# Set this to a different port for each device
# you connect!
adb -s <device-id> tcpip 9000

# Replace the <local-ip-address>
# In this example localhost: 127.0.0.1
adb -s <device-id> connect <local-ip-address>:9000

# Run this command, if you want to check the local
# ip address of the android device
adb -s <device-id> shell ip -f inet addr show wlan0

# Now you can disconnect the USB cable from the Android device.
# Confirm that the Android device is recognised by adb wirelessly.
adb devices

2. Start AskUI Controller for Each Device​

You must start a separate AskUI Controller for each Android device you are automating. The -p argument sets the port the AskUI Controller is listening on for commands. Choose a different one for each device.

tip

The -d flag specifies to which device a AskUI Controller instance connects (Read on how it works!).

Run adb devices in a terminal to get a list of connected devices. In the following example, if you want to connect to emulator-1 you use -d 0 and for emulator-2 you use -d 1.

$ adb devices
emulator-1 device product:sdk_google_phone_x86_64 model:Android_SDK_built_for_x86_64 device:generic_x86_64
emulator-2 device product:sdk_google_phone_x86 model:Android_SDK_built_for_x86 device:generic_x86

Set a different port for each AskUI Controller and specify which Android device to connect to with the -d flag.

# Activate AskUI Development Environment (ADE) first
# Connects to the first device returned by 'adb devices'
AskUI-StartController -DisplayNum 0 -Runtime android -Port 6769

# Connects to the second device returned by 'adb devices'
AskUI-StartController -DisplayNum 1 -Runtime android -Port 6770

3. Configure the askui-helper.ts​

import { UiControlClient } from 'askui';

// Client is necessary to use the askui API
let auiAndroidDevice1: UiControlClient;
let auiAndroidDevice2: UiControlClient;

jest.setTimeout(60 * 1000 * 60);

// Get your AskUI credentials from https://app.askui.com/workspaces
const credentials = {
    workspaceId: '<your-workspace-id>',
    token: '<your-token>',
}

beforeAll(async () => {

  // Connects to AskUI Controller 1 (emulator-1)
  remoteDevice1 = await UiControlClient.build({
    uiControllerUrl: "ws://127.0.0.1:6769",
    credentials,
  });
  await remoteDevice1.connect();
  
  // Connects to AskUI Controller 2 (emulator-2)
  remoteDevice2 = await UiControlClient.build({
    uiControllerUrl: "ws://127.0.0.1:6770",
    credentials,
  });
  
  await remoteDevice2.connect();
});

...

afterAll(async () => {
  remoteDevice1.disconnect();
  remoteDevice2.disconnect();
});

export { remoteDevice1, remoteDevice2 };

Write the AskUI Code​

Write the AskUI code in test/my-first-askui-test-suite.test.ts:

import { remoteDevice1, remoteDevice2 } from './helper/jest.setup';

describe('jest with askui', () => {
    it('should work with multiple devices', async () => {
        const everyElementRemote1 = await remoteDevice1.getAll().exec();
        console.log(everyElementRemote1);

        await localDevice.moveMouse(500,500).exec();
        const everyElementRemote2 = await remoteDevice2.getAll().exec();
        console.log(everyElementRemote2);
    });
});

Run the Code​

Run the command below to run the AskUI code:

Switch into ADE by running askui-shell in a Command Prompt first.
