The IDE provides a few ways to run tests. You can right-click the project node, or the Test Files folder, or a test subfolder, and select Test. You can also use the menu bar and select Run Test Project, or press Alt+F6. Run the test by right-clicking the New CUnit Test folder and selecting Test.

UITest can be used with Xamarin.Forms to write UI tests to run in the cloud on hundreds of devices.

Overview

App Center Test allows developers to write automated user interface tests for iOS and Android apps. With some minor tweaks, Xamarin.Forms apps can be tested using Xamarin.UITest, including sharing the same test code. This article introduces specific tips to get Xamarin.UITest working with Xamarin.Forms.

This guide does assume that familiarity with Xamarin.UITest. The following guides are recommended for gaining familiarity with Xamarin.UITest:

Once a UITest project has been added to a Xamarin.Forms solution, the steps for writing and running the tests for a Xamarin.Forms application are the same as for a Xamarin.Android or Xamarin.iOS application.

Requirements

Refer to Xamarin.UITest to confirm your project is ready for automated UI testing.

Adding UITest support to Xamarin.Forms apps

UITest automates the user interface by activating controls on the screen and providing input anywhere a user would normally interact with the application. To enable tests that can press a button or enter text in a box the test code will need a way to identify the controls on the screen.

To enable the UITest code to reference controls, each control needs a unique identifier. In Xamarin.Forms, the recommended way to set this identifier is by using the AutomationId property as shown below:

The AutomationId property can also be set in XAML:

Note

AutomationId is a BindableProperty and so can also be set with a binding expression.

A unique AutomationId should be added to all controls that are required for testing (including buttons, text entries, and labels whose value might need to be queried).

Warning

An InvalidOperationException will be thrown if an attempt is made to set the AutomationId property of an Element more than once.

iOS application project

Test-project Mac Os X

To run tests on iOS, the Xamarin Test Cloud Agent NuGet package must be added to the project. Once it's been added, copy the following code into the AppDelegate.FinishedLaunching method:

The Calabash assembly uses non-public Apple APIs, which cause apps to be rejected by the App Store. However, the Xamarin.iOS linker will remove the Calabash assembly from the final IPA if it isn't explicitly referenced from code.

Note

By default, release builds don't have the ENABLE_TEST_CLOUD compiler variable, which causes the Calabash assembly to be removed from app bundle. However, debug builds do have the compiler directive defined by default, preventing the linker from removing the assembly.

The following screenshot shows the ENABLE_TEST_CLOUD compiler variable set for Debug builds:

Android application project

Unlike iOS, Android projects don't need any special startup code.

Writing UITests

For information about writing UITests, see UITest documentation. The steps below are a summary, specifically describing how the Xamarin.Forms demo UsingUITest is built.

Use AutomationId in the Xamarin.Forms UI

Before any UITests can be written, the Xamarin.Forms application user interface must be scriptable. Ensure that all controls in the user interface have a AutomationId so that they can be referenced in test code.

Referring to the AutomationId in UITests

When writing UITests, the AutomationId value is exposed differently on each platform:

iOS uses the id field.
Android uses the label field.

To write cross-platform UITests that will find the AutomationId on both iOS and Android, use the Marked test query:

The shorter form app.Query('MyButton') also works.

Adding a UITest project to an existing solution

Visual Studio has a template to help add a Xamarin.UITest project to an existing Xamarin.Forms solution:

Right-click on the solution, and select File > New Project.
From the Visual C# Templates, select the Test category. Select the UI Test App > Cross-Platform template:
This step adds a new project with the NUnit, Xamarin.UITest, and NUnitTestAdapter NuGet packages to the solution:
The NUnitTestAdapter is a third-party test runner that allows Visual Studio to run NUnit tests from Visual Studio.
The new project also has two classes in it. AppInitializer contains code to help initialize and setup tests. The other class, Tests, contains boilerplate code to help start the UITests.
Add a project reference from the UITest project to the Xamarin.Android project:
Congo bongo mac os. This step allows the NUnitTestAdapter to run the UITests for the Android app from Visual Studio.

It is possible to add a new Xamarin.UITest project to an existing solution manually:

Start by adding a new project by selecting the solution, and clicking File > Add New Project. In the New Project dialog, select Cross-platform > Tests > Xamarin Test Cloud > UI Test App:
This step adds a new project that already has the NUnit and Xamarin.UITest NuGet packages in the solution:
The new project also has two classes in it. AppInitializer contains code to help initialize and setup tests. The other class, Tests, contains boilerplate code to help start the UITests.
Disneys animated storybook: the hunchback of notre dame mac os. Select View > Pads > Unit Tests to display the Unit Test pad. Expand UsingUITest > UsingUITest.UITests > Test Apps:
Right-click on Test Apps, click on Add App Project, and select iOS and Android projects in the dialog that appears:
The Unit Test pad should now have a reference to the iOS and Android projects. This reference allows the Visual Studio for Mac test runner to execute UITests locally against the two Xamarin.Forms projects.

Adding UITest to the iOS app

There are some additional changes that need to be done to the iOS application before Xamarin.UITest will work:

Add the Xamarin Test Cloud Agent NuGet package. Right-click on Packages, select Add Packages, search NuGet for the Xamarin Test Cloud Agent and add it to the Xamarin.iOS project:
Edit the FinishedLaunching method of the project's AppDelegate class to initialize the Xamarin Test Cloud Agent when the iOS application starts, and to set the AutomationId property of the views. The FinishedLaunching method should resemble the following code example:

After adding Xamarin.UITest to the Xamarin.Forms solution, it's possible to create UITests, run them locally, and submit them to App Center Test.

Summary

Xamarin.Forms applications can be easily tested with Xamarin.UITest using a simple mechanism to expose the AutomationId as a unique view identifier for test automation. Once a UITest project has been added to a Xamarin.Forms solution, the steps for writing and running the tests for a Xamarin.Forms application are the same as for a Xamarin.Android or Xamarin.iOS application.

For information about how to submit tests to App Center Test, see Submitting UITests for Xamarin.Android or Submitting UITests for Xamarin.iOS. For more information about UITest, see App Center Test documentation.
