Automate the UI testing of your app with Xamarin.UITest for Xamarin.Forms – A practical implementation

Introduction   Testing your apps must be a go-to if you plan to ship quality applications. You can unit-test your code for flaws in the logic side of the solution. That kind of tests are extended, and there is plenty of frameworks you can use. In essence, unit tests are more coupled to the language, but UI Tests are platform independent. Some scenarios you can find mobile UI tests useful: Verify bug regressions Prove that a bug has been resolved Check app UI behaviour in different screen sizes / OS versions Automate app navigation for screenshots Check for validations Xamarin.UITest is an automation library that can be used as...

Interact with Javascript from C# using Xamarin.Forms

In one of our projects, we needed to make a navigation from a page that only contains a WebView rendering a web page, but only the web page knew when that behavior must happened, there is no way to know from the app point of view when it should happen, so we needed to call a C# method from the Javascript code of a web page.   How did we did it?   Hopefully we found this: https://docs.microsoft.com/es-es/xamarin/xamarin-forms/app-fundamentals/custom-renderer/hybridwebview   The idea is: A Xamarin.Forms View that contains the Url of the web page to load, and the method we want to call from Javascript. A renderer for each platform that will make the magic on every platform. public class HybridWebView :...

Initial Steps with Xamarin.UITest for Hybrid Apps

Recently we have used Xamarin.UITest to validate the UI of an app developed with Cordova, and Test Cloud to run such on a lot of physical devices. Assuming you have already experience creating a Xamarin.UITest project, the very first thing you will need to play with is running an emulator or a physical device to deploy the app and run the tests. Such is done with this very simple piece of code: [code language="csharp"] public class AppInitializer { public static IApp StartApp(Platform platform, Xamarin.UITest.Configuration.AppDataMode mode = Xamarin.UITest.Configuration.AppDataMode.Auto) { if (platform == Platform.Android) { return ConfigureApp .Android .EnableLocalScreenshots() .ApkFile("../../../Apps/myapp.apk") .StartApp(mode); } return ConfigureApp .iOS .EnableLocalScreenshots() .AppBundle("../../../Apps/myapp.app") .StartApp(mode); } } [/code] Please take note we are going to test the UI of a multiplatform app developed with Cordova for iOS and Android, so we decided to have a single...

Continuous delivery for Xamarin.iOS projects with TeamCity, FAKE and HockeyApp

With this new post we are going to learn how to add continuous delivery to a Xamarin.iOS project. Main components are FAKE as build automation system, TeamCity as continuous integration and deployment server and HockeyApp as storage, distribution and notification service of our client deliveries.         The advantages of continuous delivery are huge, provides visibility to projects that make use of it and speed up their development process, apart from saving time turning the delivery management into an easy task. I suppose the reader of this article has some experience configuring projects and build configurations in TeamCity. These are the ingredients and cooking procedure: -A Mac/Mac Mini with OSX and Xamarin.iOS installed. (Check you have mono and curl in your PATH environment variable) -Install TeamCity Agent in OSX. (I suggest you to install it as a login item, to ensure it gets executed...

Linker experiences with Xamarin.iOS

We experienced some problems in one of our latest projects with Xamarin.iOS, the kind of problems that are normally accompanied by a big headache. While everything worked like a charm over iOS simulator, something started to crash when running the app over a physical device. It was a simple app consuming data from a web service and being displayed via Master Detail pages with standard views so, what could be wrong? Thanks to output log while debugging over device, we found that there were some errors - with their stack trace information - from System.Data.Services.Client assembly. That component calls some reflection methods and this is why it was failing, just take a look to the next image. If you have a...

Branding a Xamarin.Forms app on Android: Accent Color

Using Android Styles
The easiest way to apply our brand color is creating a custom Android theme.

For example: if we have a simple Entry, the result Android control is showing the default colors. A focused Entry control looks like:
