… parsers Expand test coverage from 168 to 226 unit tests across multiple modules: - TSS extended tests (10): spanning all zones, exact boundaries for both strands, very small regions, zero TSS/promoter distances, and percentage calculation accuracy - TTS extended tests (8): entirely within zone, spanning TTS/downstream, negative strand downstream, exact boundaries, very large zones, and percentage accuracy for both strands - Rules extended tests (9): empty candidates, threshold failures with fallback, pctg_area filtering, multiple independent groups, three-candidate merging, no rules match fallback, and exact threshold boundaries - Overlap extended tests (9): find_search_start_index edge cases, region completely within exon, spanning multiple exons, single exon genes, beyond distance threshold, transcript/gene level processing, and negative strand first exon handling - Output extended tests (6): metadata with newlines/whitespace, special characters, exact header output verification, negative coordinates, merged transcripts format, and all strands handling - Parser BED extended tests (5): whitespace handling, very long lines, mixed valid/invalid lines, tab-only lines, and coordinate ordering - Parser GTF extended tests (7): overlapping genes, malformed attributes, CDS/UTR entries, quoted values with spaces, no exon entries, different sources, and max length tracking across chromosomes - Config comprehensive tests (6): whitespace in rules, all area combinations, extreme values, percentage ranges, report level default, and distance overflow prevention
Run cargo fmt to fix formatting issues that were causing CI to fail. The changes include proper line breaks in assert! macros, Candidate::new() calls, and writeln! macro chains. Co-Authored-By: Claude (claude-opus-4-5) <noreply@anthropic.com>
