Let’s hangup with the most commonly used code for Xamarin UITest

Once the development team is done with the creation of an application under the Xamarin tech stack, now its time to do a automated testing for that application, well in this process may be the testing team or the developer can stumble across the testing process in  Xamarin.UITest. Additionally for the automated app testing, The Xamarin.UI can work in a great way in order to bring the application the upper-level with zero error counts and bugs. In a way to the move with the Xamarin.UITest must check the developer have a best practice on it, along with the core expertise in the Page Object Pattern, else, you have to face major mess and disorders in the Xamarin.UITest with having less and improper knowledge and practice on it.

While with the good hands practice on it, when you set up everything in a proper way then, you can successfully test your cross-platform Xamarin mobile application with the UI on 1000+ devices using the Visual Studio App Center.

In order to add a automate test feature in the newer creating application, at the creation time of a new app development project in visual studio, for the first simply select “Add an automated UI Test Project”  and then add the mentioned code functionality in the project.

<StackLayout Margin=”20″>

<Label  Text=”Only enter digits” />

<Entry  AutomationId=”entryDigits” />

<Button Text=”Validate” />

<Label  AutomationId=”lblResult” IsVisible=”false” />


Implementing this simple example, you can aslo covers the most commonly use action app code inside the application as:

  • Inserting txt i entry-field
  • Form submission using a button
  • Output result validation

Let’s check now, how it will work on Xamarin.UITest:

In a way to check test functionality first, we need to first check the Xamarin.UITest works with the Marked method, as this method allows us to search the elements in the UI that are marked by passing on a string value.

When you hook up the REPL through the app.Repl() and enter the tree-command, we can see how our simple application is built up. The automation is translated to label, which you can use to automate. The text-value can also be used. So when we can simply pass these values to the Marked-method to get the element that we want. For example, “entryDigits” would give us the input field while “Validate” would give us access to the Button.

Enter text method

Additionally, to implement the enter text feature in an application, we are now using the EnterText method which makes us enable to add text in the input field. The first parameter has been passed through this marked vales and then the second value we will add in the test.

var inputToValidate = “12345”;

app.EnterText(“entryDigits”, inputToValidate);

The press button and validation

After adding the input field in the app, its time to add a press button in it, for this we need to use the Tap method.


Also, along with this, we are adding a validation feature in it which will help us to validate the result of inserted text.

app.WaitForElement(“lblResult”, “Results didn’t return”);

var validationResult = app.Query(“lblResult”)[0].Text;

Alongside these commonly used methods, here are some more like app.screenshot, app.flash, copy, etc, that a developer need to use in almost every application that they are developing.

If you are too in a way to build a cross-platform mobile application with including a bunch of uniques and common features then do not make any more delay to get in touch with us at Hire Xamarrin developer. We will feel glad to assist you with the best possible and effective services.
