The Windows Phone Marketplace Test Kit provides a suite of automated, monitored, and manual tests to help make sure that your applications are accepted in the Marketplace the first time you submit them. The test kit enables you to identify and fix issues prior to Marketplace submission, which saves time in the submission process. You can use the test kit to evaluate applications that target Windows Phone OS 7.1 or later.
The Marketplace Test Kit is a component of the Windows Phone SDK. For information about how to install the Windows Phone SDK, see Installing the Windows Phone SDK.
