Unit Testing is an important part of the application development life cycle for any platform. Visual Studio users no longer need to depend on 3rd<\/sup> party frameworks for unit tests on Windows Phone. The Windows Phone Unit Test framework delivered in CTP2 of Visual Studio Update 2 provides a consistent experience for developers to author, run and debug tests for Windows Phone 8 platform. This article walks you through the steps to start unit testing on Windows Phone.<\/p>\n

Prerequisites<\/strong><\/p>\n

    \n
  1. Visual Studio 2012 <\/li>\n
  2. Windows Phone SDK 8.0<\/a> <\/li>\n
  3. Visual Studio 2012 Update 2 CTP 2<\/a> <\/li>\n<\/ol>\n

    Note: You need a 64 bit Windows 8 physical machine (with Hyper-V enabled) to run unit tests on Windows Phone Emulator.<\/p>\n

    One Framework \u2013 Multiple Platforms<\/strong><\/p>\n

    You can now write Unit Tests for Windows Phone in C# by creating a new \u201cWindows Phone Unit Test App\u201d project under Visual C#\/Windows Phone. Tests are executed on the target device by installing the Unit Test app on the phone.<\/p>\n

    Whether you are writing classic unit tests, Windows Store unit tests, or Windows Phone unit tests \u2013 Visual Studio automatically adds all the necessary references and you are ready to start writing tests using the familiar MS Test framework. You no longer need to learn multiple frameworks to author unit tests for different platforms.<\/p>\n

    Running Tests from Visual Studio<\/strong><\/p>\n

    The Phone UT framework is designed as an adapter on top of the extensible Visual Studio 2012 unit testing platform (similar to other adapters like nUnit, xUnit). With this, the whole Visual Studio Test Driven Development experience is now extended to Windows Phone. Tests are discovered and displayed in the familiar Test Explorer window. Right from within the IDE, users can group\/filter tests using traits, turn on continuous test runner to view test results after each build, and debug or run selected (or failed) set of tests.<\/p>\n\n\n\n

    \n Figure 4:Set Target Device <\/em>\n <\/p>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

    Visual Studio uses the target device set on the Run palette to install the unit test app, run tests, and return results. Supported targets include Emulators (only available when Hyper-V is enabled) and Windows Phone 8 devices physically connected to the machine. Developers can author, run, and debug tests on any of the target devices without leaving the IDE. While unit tests are running on the device, a ‘Tests Running’ screen will be shown.<\/p>\n

    **Running Tests from Command Line **<\/p>\n

    As I mentioned earlier, since Phone UT is designed as an adapter to unit testing platform, you can use vstest.console.exe<\/a> to execute unit tests from command line. You can also choose to export the results to Visual Studio Test Results File using \/Logger:trx<\/strong>.<\/p>\n

    By default Emulator WVGA 512MB is the target device to execute tests, use run settings<\/a> to change target device (Sample run settings attached).<\/p>\n
