### Overview

The mouse Functional Verification Tests (FVTs) exercise the Int86() DOS interface for mouse functions. The tests are implemented with a special variation of the Device Driver Test Tool (called DOSMOUSE), which uses much of the Device Driver Test Tool code; however, DOSMOUSE does not use the multithread capability. Specific mouse function code is included in the DOSMOUSE.EXE, not in a DLL, as is it done for the DDTT running in OS/2.

These tests run in a DOS window. Each test is defined in a script file and these files 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, clearly indicating the actual execution sequence.
