Good goal, except that unit tests are not panacea---our ultimate obligation is to give a stable behaviour to the end users and end-to-end testing is still needed. We would benefit from having tests at both levels. > Unit testing in C requires a separate testing harness that we ideally > would like to be TAP-style and to come with a non-restrictive license. > > Fortunately, there already exists a C TAP harness library[2] with an MIT > license (at least for the files included in this series). Yup. Consistency with our existing test framework would make it easier to adopt for all of us. Good goal.
