Enhance tests (#185) * Initial attempt to create unit tests for DATA class (tnc). * Completed initial set of tests. * Adding pytest to install packages. * Corrects issue #173 fix I didn't look carefully enough at `helpers.check_callsign` to see that it returns a list. The first element of the list is `True`/`False`. * Making check_callsign evaluation more consistent. * Update .gitignore this is more a test commit to see if GitHub Client for MacOS is working, * mkfifo test prototype First partially working prototype for testing the full tnc with mkfifo named pipes. * single tnc test file moved to a single file for running tnc tests * fixed typo * Added parameters to tests. Make other minor tweaks and documentation. * Clean up two existing tests. Adapted both tests to pytest and maintained compatibility with existing ctest method. Tweaked CMakeLists.txt . * Adding pure python highsnr_stdio_P_P_multi test. Intended to replace highsnr_stdio_P_P_multi which uses POSIX shell. * Adding pure python highsnr_stdio_P_P_datac0 test. Intended to replace highsnr_stdio_P_P_datac0 which uses POSIX shell. * Parameterize recent tests. Renamed datac0 to datacx after including all data codecs in test. * Parameterize mode as well. Add ability to run tests from main directory as well as within test/. * Add list of tests and brief descriptions. * Add more native python tests conversions. * Update README with new tests. * Tweak README again. * Rename test to be findable by pytest. * Rename test for ctest. * Update correct file this time. * Minor test tweaks. * Add modem test proof-of-concept. * Adjustment to ARQ short test. * Various refactorings. Type hints, trailing backslash, range usage, etc. * Ignore unknown arguments in argparse. * Minor cleanups. * Update test/README.md. * Update test_pa to quiet pylint. * Give up trying to suppress structlog output. * Correct module comments. * Remove excess trailing spaces. * Remove excess newlines. * Various refactorings. Type hints, trailing backslash, range usage, etc. * mkfifo test prototype First partially working prototype for testing the full tnc with mkfifo named pipes. * Update test_tnc and tweak IRS/ISS. * Correct test_modem to detect failures. * Trying to be less dependent on env variables. * Add IRS/ISS tests to ctests * Pin codec2 revision to v1.0.3. * Correcting git mistake. * Pin codec2 revision to master. This should be a specific release, that implements freedv_set_tuning_range. Co-authored-by: DJ2LS <75909252+DJ2LS@users.noreply.github.com>
