TestComplete samples (both built-in and additional) are located in the <Users>\Public\Public Documents\TestComplete 15 Samples folder.
Some file managers display the Public Documents folder as Documents.
Xamarin.Forms samples contain test projects that demonstrate how to test a Xamarin.Forms application. The sample application is the Xamarin.Forms version of the Orders application which has a table of purchase orders. You can view the list of existing orders, add new orders to the list, and modify or remove the existing ones.
These samples are a part of the additional sample package. To use them, download this package from support.smartbear.com/testcomplete/downloads/samples and install it.
After the installation is over, you can find the samples in the <TestComplete 15 Samples>\Mobile\Xamarin.Forms folder.
