From dd61ad2388c7a7d5dabfc9cc8ca94c22bbc912e3 Mon Sep 17 00:00:00 2001 From: Claude Date: Fri, 27 Feb 2026 05:03:04 +0000 Subject: [PATCH] test: add 14 spec test files inspired by Oils coverage gaps Add comprehensive spec tests for bashkit behaviors not previously covered, inspired by the Oils (oilshell) test suite methodology. Each file links to the original Oils test for reference. New test files (high-value gaps): - word-split.test.sh: 39 tests for IFS, $@/$*, word elision (36 skipped) - quote.test.sh: 22 tests for quoting edge cases (11 skipped) - parse-errors.test.sh: 18 tests for parser error detection (11 skipped) - shell-grammar.test.sh: 22 tests for grammar edge cases (0 skipped) - empty-bodies.test.sh: 8 tests for empty loop/function bodies (5 skipped) - exit-status.test.sh: 17 tests for exit code propagation (9 skipped) - subshell.test.sh: 13 tests for subshell isolation (4 skipped) New test files (medium-value gaps): - nameref.test.sh: 14 tests for local -n / typeset -n (14 skipped) - var-op-test.test.sh: 19 tests for ${:-} ${:+} ${:=} ${:?} (14 skipped) - heredoc-edge.test.sh: 16 tests for heredoc edge cases (6 skipped) - unicode.test.sh: 17 tests for unicode handling (6 skipped) - alias.test.sh: 15 tests for alias expansion (15 skipped) - temp-binding.test.sh: 10 tests for FOO=bar cmd (0 skipped) - arith-dynamic.test.sh: 14 tests for dynamic arithmetic (5 skipped) Total: 244 new tests, 108 passing, 136 skipped with TODO markers. https://claude.ai/code/session_01PaZ7p23KzidUUWEP5DwDYN --- .../tests/spec_cases/bash/alias.test.sh |
