Tizen UI Automation Test using Appium

SeungHyun Choi

Engineer

What is Appium?

Appium is an open-source test automation framework. The Tizen driver is added in Appium, so you can test UI automatically on the Tizen platform. This blog shows you how.

Install and start Appium

Samsung recommends installing the Appium framework on a server that has a Tizen emulator or a connected device.

First, install nodejs so you can use the npm package manager and run Appium.

We recommend you install the latest stable version, although Appium supports node.js 6+.

If you have installed node.js, follow these steps:

  1. Clone Appium git

      ~$ git clone https://github.com/appium/appium.git

  2. Go to the Appium folder and npm install

       ~$ npm install

  3. Build Appium with gulp

       ~$ gulp transpile

  4. Run Appium:

       ~$ nodejs .

If Appium runs correctly, you see results similar to the following:

Add Tizen.Appium to Tizen .NET applications

To automate your Tizen .NET applications, add NuGet Tizen.Appium to your application project.

  1. Install Tizen.Appium for ElmSharp or NUI projects.
  2. Install Tizen.Appium.Forms for Xamarin.Forms projects.

Initialize Tizen.Appium

Add the following code to initialize Tizen.Appium.

ElmSharp application

using Tizen.Appium;

class App : CoreUIApplication
{
    protected override void OnCreate()
    {
        base.OnCreate();
        TizenAppium.StartService(AppType.ElmSharp);
        //...
     }
     //...
}

NUI application

using Tizen.Appium;

class Program : NUIApplication
{
    protected override void OnCreate()
    {
        base.OnCreate();
        TizenAppium.StartService(AppType.NUI);
        //...
    }
    //...
}

Xamarin.Forms application

using Tizen.Appium;

class Program : global::Xamarin.Forms.Platform.Tizen.FormsApplication
{
    protected override void OnCreate()
    {
        base.OnCreate();
        TizenAppium.StartService();
        LoadApplication(new App());
        //...
    }
    //...
}

Set AutomationId in the test application

Tizen.Appium automates the user interface by activating controls on the screen and performing input. To do this, assign a unique identifier to each control. To set the identifier, use the AutomationId property, as shown in the following example.

Note: An exception is thrown if the AutomationId property is set more than once.

ElmSharp application

var button = new Button(window)
{
    Text = "button",
    AutomationId = "button"
};

NUI application

PushButton button = new PushButton
{
    LabelText = "Button",
    AutomationId = "button"
}

Xamarin.Forms application

Button button = new Button
{
    Text = "Button",
    AutomationId = "button"
}

Write your test script

Visual Studio has a template to help you add a Tizen .NET UI Test project to your application solution, which you can get as follows:

  1. Right-click on the solution, and select File > New Project.
  2. From Tizen Templates, select the UI Test App template.

How to create a UI test project manually

1 Create a test project in Visual Studio

Select Visual C# > Test > NUnit Test Project.

2 Add Appium.WebDriver as a package reference to your project (*.csporj)

Tizen driver is supported as of Appium.WebDriver 4.0.0.2-beta. We recommend that you use this version or later.

3 Add the following code to initialize TizenDriver and set AppiumOptions

public class UITest
{
    TizenDriver<TizenElement> _driver;

    [SetUp]
    public void Setup()
    {
        AppiumOptions appiumOptions = new AppiumOptions();

        appiumOptions.AddAdditionalCapability("platformName", "Tizen");
        appiumOptions.AddAdditionalCapability("deviceName", "emulator-26101");

        //Xamarin.Forms
        appiumOptions.AddAdditionalCapability("appPackage", "org.tizen.example.FormsApp.Tizen.Mobile");

        //ElmSharp
        //appiumOptions.AddAdditionalCapability("appPackage", "org.tizen.example.ElmSharpApp");

        //NUI
        //appiumOptions.AddAdditionalCapability("appPackage", "org.tizen.example.NUIApp");

        _driver = new TizenDriver<TizenElement>(new Uri("http://127.0.0.1:4723/wd/hub"), appiumOptions);
    }

    [Test]
    public void Test1()
    {
        _driver.FindElementByAccessibilityId("Button").Click();
    }
}
  • For more information about writing test scripts, see Supported Commands
  • Be sure to set the Appium server IP (for example, 127.0.0.1:4723) and port number. We recommend you use the same port number as the Appium default, which is 4723.
  • To find a device name, use the sdb devices command.

4 Install NUnit3 Test Adapter

  1. Go to Tools > Extension and Updates.
  2. Select Online. Search and select NUnit 3 Test Adapter.

5 Open Test Explorer

  1. Go to Test > Windows > Test Explorer.
  2. Right-click on your test, and select Run Selected Test.

Run a UI automation test

If you run the Appium project, you can control the application according to the created script.

The following image shows an Appium project running.

Run a UI automation test with the Tizen.NET application

If you create a Tizen.NET application, you can run it on Tizen devices. You can also use Appium for automatic UI tests and verifying your application on Tizen.

The following automation test example runs the calculator application. You can test simple and complex applications.
