From 4c9058a27c683c573d77dbc6ddd943f714af6504 Mon Sep 17 00:00:00 2001 From: naoNao89 <90588855+naoNao89@users.noreply.github.com> Date: Thu, 30 Oct 2025 23:04:38 +0700 Subject: [PATCH 1/7] stty: Add 101 unit tests and 16 integration tests to improve coverage Add comprehensive test coverage for stty: Unit tests (src/uu/stty/src/stty.rs): - Flag struct methods and builder pattern (7 tests) - Control character parsing and formatting (19 tests) - All combination settings expansion (26 tests) - Termios modification functions (13 tests) - String-to-flag/combo/baud parsing (19 tests) - TermiosFlag trait implementations (5 tests) - Helper and utility functions (10 tests) - Trait implementations (2 tests) Integration tests (tests/by-util/test_stty.rs): - Help and version output validation (2 tests) - Invalid argument handling (3 tests) - Control character overflow validation (2 tests) - Grouped flag removal validation (1 test) - File argument error handling (1 test) - Conflicting print modes (1 test) - Additional TTY-dependent tests (6 tests, ignored in CI) Unit test coverage improved from 0% to 43.76% (207/473 lines). Integration tests validate argument parsing and error handling.

Integration tests validate actual command behavior. Coverage improved from 0% to 43.76% (207/473 lines).
