### Device Driver Test Tool and Suites: Mouse

Tool Description:

The Functional Verification Tests (FVTs) for the mouse exercise the Int86() DOS interface for mouse functions. A subset of the mouse functions that are implemented in these tests can be found in the "Microsoft Mouse Programmer' s Reference."

The tests are implemented with a special variation of the Device Driver Test Tool (DDTT) called DOSMOUSE, which uses much of the DDTT code. However , DOSMOUSE does not use the multi-thread capability. Specific mouse function code is included in the DOSMOUSE.EXE, not in a DLL as is it for the DDTT running in OS/2. These mouse tests run in a DOS window.

Each test is defined in a script file that can be modified using a text editor to create additional, specialized test cases. The test scripts give the user a repeatable set of tests that demonstrate mouse functions. Test cases log all information to a log file that clearly indicates the actual execution sequence for error-tracking purposes.
