More information
Most of the DirectDraw tests are in Fnddraw.exe. You can run Fnddraw.exe outside the Windows HCK Studio, and then select initial tests. On the Tests menu, click Select Tests.
The test titles that are listed in the DCT shell do not directly match the test names in Fnddraw.exe. In fact, the names in the DCT often refer to a group of Fnddraw tests. You can obtain the Fnddraw test names from the DCT log file.
You can pause many Fnddraw tests (especially Blt-related tests) to give you time to visually analyze the Blt results. Use the Pause key to pause and resume.
Use the Esc key to stop a test run. This might take a minute or two. Some tests are more responsive than others.
