The Driver Test Manager (DTM) is a test automation framework provided by Microsoft in the Windows Driver Kit (WDK). The primary purpose of the DTM is to provide automated scheduling and execution of the driver tests that hardware vendors are required to pass in order to qualify to use the Microsoft Designed for Windows Logo. Recent releases DTM have been release as WLK (Windows Logo Kit), the releases have been separated from the WDK releases. The DTM is a version of the same test automation framework that Microsoft uses to test its Windows operating system. Internally the product is referred to as Windows Test Technologies (WTT). The external version has been modified to meet the needs of hardware organizations and to remove features which have no application outside of Microsoft. In addition to the ability to automate the Logo tests, the DTM enables users to automate driver tests which they have created themselves. These tests can be mixed and matched with the Logo tests provided by Microsoft to create a custom test pass enabling organizations to use the DTM to validate drivers in any way they see fit.
