Some of the old software before 2010 may not be able to install/run normally on x64 or Windows 10 systems. Be aware of it before purchasing it.
Microsoft Visual Test, originally known as MS-Test, was an automated testing tool for Windows applications developed by Microsoft and later sold to Rational Software.
MS-Test was developed for internal use in Microsoft but became a commercial product at the beginning of 1992. MS-Test automated the process of testing Windows applications. It combined a Windows development language, Basic, with a testing-oriented API.
Version 2.0 in 1993 had provided support for Windows 3.1. In 1994 MS-Test version 3.0 advanced from 16-bit systems to 32-bit. With Version 4.0 in 1995, it was hosted within Visual Studio and renamed to Visual Test. It was able to support the testing of the new application control that arrived with Windows 95 and NT.
