| 3 | # FERP Extended Grep Test Suite |
| 4 | # Tests edge cases, corner cases, and obscure grep behaviors |
| 5 | # |
| 6 | # This test suite covers: |
| 7 | # 1. Multiple pattern flags (-e, -f) |
| 8 | # 2. Backreferences in BRE |
| 9 | # 3. Null-data mode (-z) |
| 10 | # 4. Binary file handling |
| 11 | # 5. Recursive directory options |
| 12 | # 6. Context edge cases |
| 13 | # 7. Output format options (-T, -Z, --label) |
| 14 | # 8. Regex edge cases (empty matches, unicode, long patterns) |
| 15 | # 9. BRE vs ERE differences |
| 16 | # 10. Error handling scenarios |
| 17 | # 11. Unusual input (long lines, mixed line endings, etc.) |
| 18 | # 12. Flag interaction edge cases |
| 19 | # 13. PCRE-specific features (-P) |
| 20 | # |
| 21 | # Usage: ./extended_grep_test.sh [--verbose] [--stop-on-fail] [--filter PATTERN] |
