This blog assumes that you have a prior understanding of Coded UI Test for Windows Store Apps. If not, Please read the "Introduction" blog of Coded UI Test for Windows Store Apps. This blog explains how to launch a Windows Store Application using Coded UI test.
API Definition and Usage:
In Visual Studio 2013, Users will be able create and test Windows Store XAML Apps using Coded UI Test. In Similar fashion to other technology controls, we have added XamlWindow, XamlButton, XamlTextBox etc. to test Xaml Windows Store Apps. To Launch a Windows Store App, we will be using "XamlWindow.Launch()" API:
XamlWindow.Launch API takes a single argument which is "appPackageFamilyName" and returns an object of XamlWindow. This XamlWindow object represents the window of Windows Store App that gets launched.
XamlWindow Launch API takes a single argument which uniquely represents a specific Windows Store App. Package Family Name of a Windows Store App appended by its' App Id can uniquely represent a Windows Store App. These values are configured by the Application developers during App development. Coded UI Test recommends using Coded UI Test Builder for finding AppPackageFamilyName of a Windows Store App. Follow these steps to find the AppPackageFamilyName of a Windows Store App:
Automation Id of the tile represents the "AppPackageFamilyName". This is the argument for the Launch API.
We will be using "File Picker" SDK sample from MSDN. As you can see in below image, Coded UI Test builder shows the automation id of the tile i.e. "AppPackageFamilyName" of the App. "File Picker SDK sample" tile is located using Builder and the Automation Id property shows the "AppPackageFamilyName". XamlWindow.Launch will launch the app if this string is given as parameter. Note that the app need not be pinned in start menu for Coded UI Test to launch the Application. Once you find the AppPackageFamilyName, you can unpin it from the Start Menu if you wish to do so.
Example: Automation Id here is "Microsoft.SDKSamples.FilePicker.CS_8wekyb3d8bbwe!FilePickerSample".
Launch API Behaviour:
XamlWindow appWindow = XamlWindow.Launch("Microsoft.SDKSamples.FilePicker.CS_8wekyb3d8bbwe!FilePickerSample"); appWindow.CloseOnPlaybackCleanup = false;
1. Let us take a scenario where Coded UI Test launches the app afresh i.e. the app was not launched previously after the login. Application will be launched afresh. We will launch the app as below:
2. Now, Let us do some actions in the application manually and minimize it. Click on "3) Pick a folder" option and pick "Documents" folder. It should look like this:
3. If we launch the App again using the API, then it will just launch the minimized app in the same state as above screenshot. This is because the "Activated" event of the app does not bring the app to fresh state which is what the developer intended for this app.
4. If we close the app's window object using "Close()" API and call the Launch API again, it will launch the App afresh as in the first screenshot.
XamlWindow appWindow = XamlWindow.Launch("Microsoft.SDKSamples.FilePicker.CS_8wekyb3d8bbwe!FilePickerSample"); Playback.Wait(2000); appWindow.Close(); Playback.Wait(1000); XamlWindow.Launch("Microsoft.SDKSamples.FilePicker.CS_8wekyb3d8bbwe!FilePickerSample");
5. In some scenarios, an action in a store app can launch another store application like for example, opening a Mail client or a sharing app. The second app that was launched by some action might get closed immediately after its use and brought up again whenever it is required. In these cases, the XamlWindow object of the second app should have "AlwaysSearch" option to be set on it. Reason being that the second app might get automatically closed and reopened multiple times and so, the app window object can become stale causing issues. "AlwaysSearch" option tells the Coded UI test to search for the window again.
Mouse.Click(someButton); // Launches another appXamlWindow secondAppWindow = new XamlWindow();// Configure Search properties of the newly launched window here or use Coded UI Test Builder to capture these propertiessecondAppWindow.SearchConfigurations.Add(SearchConfiguration.AlwaysSearch);
I have a problem where my test code is able to launch the app if I install the app from Store but when I install the app from Build drop, than Xaml.Launch not able to launch the app. Is there settings I need to change for this method to work on not yet published versions of the app? Please advice.
