Attached is the quality assurance process for the tsinvest program suite, (ie., the tsinvest(1), tsinvestsim(1), tsshannoneffective(1), tsinvestdb(1), and csv2tsinvest(1) programs.) The programs have a substantial regression test suite (see the tests directory in the source tree, or the Tests page that describes how every line of code is exercised in the programs, and all available command line options.) The regression test suite exercises the programs in an envelope of corner solutions taken from market data, and fabricated using theoretical values where the program's results can be compared against theoretical expectations. The results compare favorably with the theoretical values. The regression suite also contains a fragment of the US equity market exchange tickers, which is used to exercise the tsinvest program, and the internal data structures dumped to a file. This file is then used by the tsinvestsim program to provide theoretically derived data to the tsinvest program, and the two results compared to gain confidence in the stochastic methods used. The two results compare favorably, as table I and III show on the Usage page. In addition, the tsshannoneffective program is a test facility that exercises certain complex functionality of the tsinvest program. Additionally, various static verifications were performed. A description, and the results, are attached for each program. As a support metric for the program suite, the collateral documentation for the program(s) is ninety six lines of collateral per one line of executable code. The process described is not comprehensive. However, it is probably minimally adequate for a useful and maintainable program. By no means can it be regarded as qualifying the program for mission critical applications.
The following is the McCabe and Halstead metrics for the program, tsinvest, as generated by "CodeCheck" from Abraxas Software, Inc., 7033 SW Macadam Ave., Portland, OR 97219, USA, telephone (503) 244-5253. The program has only 908 lines of executable code, and 325 lines of declarations, out of 8402 total lines, of which, 4043 lines are comments, (the rest are whitespace, punctuation, compiler directives, etc.) Over 99% of the lines of executable code is commented. The diagnostics from CodeCheck seem within reasonable bounds, (no errors or warnings were permitted, excepting as noted in tsinvest.c concerning line length of comments, size of functions, etc.) The lint product from Gimpel Software, 3207 Hogarth Lane, Collegeville, PA, 19426, USA, telephone (215) 584-4261, was used to verify the code statics, (no errors or warnings were permitted,) in addition to the lint on the ATT SysV, Rel. 4.2 system that was used for development, (again, no errors or warnings were permitted.) The GNU compiler, GCC, was used for cross development, with all warnings enabled. No errors or warnings were permitted. Memory allocation robustness, (memory boundary overruns and referencing of un-allocated areas,) was verified using Bruce Perens' "efence" library, c/o Pixar, 1001 West Cutting Blvd., Suite 200, Richmond, CA 94804, telephone (510) 215-3502, Bruce@Pixar.com. The sources were formated for consistency with the indent program, available via anonymous ftp from ftp://prep.ai.mit.edu/pub/gnu/ in /pub/gnu/indent.1.9.1.tar.gz.

The following is the McCabe and Halstead metrics for the program, tsinvestdb, as generated by "CodeCheck" from Abraxas Software, Inc., 7033 SW Macadam Ave., Portland, OR 97219, USA, telephone (503) 244-5253. The program has only 199 lines of executable code, and 75 lines of declarations, out of 1989 total lines, of which, 682 lines are comments, (the rest are whitespace, punctuation, compiler directives, etc.) Over 99% of the lines of executable code is commented. The diagnostics from CodeCheck seem within reasonable bounds, (no errors or warnings were permitted, excepting as noted in tsinvestdb.c concerning line length of comments, size of functions, etc.) The lint product from Gimpel Software, 3207 Hogarth Lane, Collegeville, PA, 19426, USA, telephone (215) 584-4261, was used to verify the code statics, (no errors or warnings were permitted,) in addition to the lint on the ATT SysV, Rel. 4.2 system that was used for development, (again, no errors or warnings were permitted.) The GNU compiler, GCC, was used for cross development, with all warnings enabled. No errors or warnings were permitted. Memory allocation robustness, (memory boundary overruns and referencing of un-allocated areas,) was verified using Bruce Perens' "efence" library, c/o Pixar, 1001 West Cutting Blvd., Suite 200, Richmond, CA 94804, telephone (510) 215-3502, Bruce@Pixar.com. The sources were formated for consistency with the indent program, available via anonymous ftp from ftp://prep.ai.mit.edu/pub/gnu/ in /pub/gnu/indent.1.9.1.tar.gz.
