The test harness is written in Prolog itself. It consists of a test runner and a test result browser, as well as a report generator. This document does not contain the source code of the harness programs. A version of the source code of the harness programs can be found on the following web site:www.jekejeke.ch/idatab/doclet/blog/en/docs/05_run/07_compliance/harness/package.jsp
Further the source code is also bundled in the suprun.zip when downloading the Jekejeke Prolog runtime library from the web site.
