Introduction
Beginning in the early 1990s developers at Software Research began assembling tools that supported software test and analysis activities of various types. All of these tools were developed first in a Unix context, because prior to the late 1980s most software development was done in UNIX.

Windows 3.0, released in 1990, was a completely different (and in many ways not as friendly) development environment, but was quickly become ubiquitous -- as compared with Unix's moderate and rapidly decreasing market share.

• CAPBAK:
  The earliest innovative testing product effort was CAPBAK/Unix, which was based redirecting the input and output of the Unix system cu utility. (See Linux man page; cu(1) .)

  The idea was that if we could record [capture] and then inject the recording [playback] we would mechanize a common testing task -- what a human tester would do -- but capture the test in a permanent and unambiguous way. Hence the "CAPBAK" product name.

  Later, addressing the need for test tools for UNIX workstations, the UNIX CAPBAK/X system was developed. CAPBAK/X was based on using the "XTrap" capability that was included (but now well documented) in the MIT Xwindows display system. (See X Window System.) Xtrap intercepted from and interjected into the XWindows command/event loop; we obtained the Xtrap server extension documentation from DEC software engineers. (See: XTrap sample clients.)

• TCAT:
  In parallel with CAPBAK/Unix the team was building a C coverage analyzer, based on Edward Miller's prior experience in building test coverage analysis tools (TCAT's) for FORTRAN (US Army), Jovial/J73 (US Air Force), CMS-2Y (US Navy), and COBOL (technology partner Harry Sneed of SSS, GmbH, in Sauerlach, Germany).

  Ultimately, only TCAT for C/C++ and Java were ever released, but the system files contain instrumentor components for Ada, Cobol, Fortran 77, and Pascal. All of these shared architecture with a common "runtime" [data collection] component and common "cover" data display (including graphical displays) component.

Documentation Summary
Below is a complete list of surviving product documentation, with publication dates from 1996 through 1999. All of the documentation was done in Adobe's framemaker system, which allowed for production quality postscript (*.ps) files as well as PDF files.
