Extensability- Extend Common Services

Learn how to extend BELLATRIX common services.

Example

using Bellatrix.Desktop.GettingStarted.AppService.Extensions;
using Microsoft.VisualStudio.TestTools.UnitTesting;

namespace Bellatrix.Desktop.GettingStarted
{
    [TestClass]
    [App(Constants.WpfAppPath, AppBehavior.RestartEveryTime)]
    public class ExtendExistingCommonServicesTests : DesktopTest
    {
        [TestMethod]
        public void CommonActionsWithDesktopControls_Wpf()
        {
            // 2. Use newly added login method which is not part of the original implementation of the common service.
            App.AppService.LoginToApp("bellatrix", "topSecret");

            var calendar = App.ElementCreateService.CreateByAutomationId<Calendar>("calendar");

            Assert.AreEqual(false, calendar.IsDisabled);

            var checkBox = App.ElementCreateService.CreateByName<CheckBox>("BellaCheckBox");

            checkBox.Check();

            Assert.IsTrue(checkBox.IsChecked);

            var comboBox = App.ElementCreateService.CreateByAutomationId<ComboBox>("select");

            comboBox.SelectByText("Item2");

            Assert.AreEqual("Item2", comboBox.InnerText);

            var label = App.ElementCreateService.CreateByName<Label>("Result Label");

            Assert.IsTrue(label.IsPresent);

            var radioButton = App.ElementCreateService.CreateByName<RadioButton>("RadioButton");

            radioButton.Click();

            Assert.IsTrue(radioButton.IsChecked);
        }
    }
}

Explanations

public static class NavigationServiceExtensions
{
    public static void LoginToApp(this Services.AppService appService, string userName, string password)
    {
        var elementCreateService = new ElementCreateService();
        var userNameField = elementCreateService.CreateByAutomationId<TextField>("textBox");
        var passwordField = elementCreateService.CreateByAutomationId<Password>("passwordBox");
        var loginButton = elementCreateService.CreateByName<Button>("E Button");

        userNameField.SetText(userName);
        passwordField.SetPassword(password);
        loginButton.Click();
    }
}

One way to extend the BELLATRIX common services is to create an extension method for the additional action.

  1. Place it in a static class like this one.
  2. Create a static method for the action.
  3. Pass the common service as a parameter with the keyword ‘this’.
  4. Access the native driver via WrappedDriver.

Later to use the method in your tests, add a using statement containing this class’s namespace.

using Bellatrix.Desktop.GettingStarted.AppService.Extensions;
using Microsoft.VisualStudio.TestTools.UnitTesting;

namespace Bellatrix.Desktop.GettingStarted

To use the additional method you created, add a using statement to the extension methods’ namespace.

App.AppService.LoginToApp("bellatrix", "topSecret");

Use newly added login method which is not part of the original implementation of the common service.
