os-test expansion

Comprehensive POSIX compliance test suite for operating system implementations

os-test measures interoperability and differences between every POSIX operating system (Linux, BSD, macOS, and many more). The objective is to finish scaling os-test from a moderate coverage to a high coverage of POSIX, realizing the benefits os-test can offer by expanding it into related areas, providing a freely licensed test suite that helps the whole POSIX community. This project supports interoperability and competition between operating systems. os-test continuously publishes test results for every POSIX OS as open data. os-test improves interoperability, since application vendors are able to know what behaviors they can actually use to write portable applications for all operating systems, operating system vendors can identify and fix their conformance issues, and the POSIX standard authors can measure adoption/rejection of the new POSIX.1 2024 standard.
