Daily Test Coverage Improver: Comprehensive TextConversions test coverage
This commit significantly improves test coverage for the TextConversions module in FSharp.Data.Runtime.Utilities by adding 14 new comprehensive test methods. ## Problems Found - TextConversions had minimal test coverage with only 4 basic tests - Key conversion methods like AsInteger, AsInteger64, AsTimeSpan, AsGuid were untested - Missing values handling and currency adorner removal were not validated - Edge cases like scientific notation, special float values, and malformed input were uncovered - No validation of whitespace handling and format variations ## Actions Taken Added 14 new test methods covering: **Enhanced Boolean Conversions:** - Whitespace handling and trimming - Additional valid value formats (YES/NO, TRUE/FALSE variations) **New Integer & Integer64 Conversions:** - Positive and negative number parsing - Currency adorner removal ($, €, ¥, £, ₹) - Non-currency adorner handling (%, ‰, ‱) - Max/min value boundary testing - Invalid input validation **Enhanced Decimal Conversions:** - Various decimal formats (.5, 1000.00) - Percentage notation handling - Invalid format detection **New Float Conversions with Missing Values:** - Scientific notation (1.23e10, 1.23e-5, 1.23E+3) - Special values (Infinity, -Infinity, NaN) - Missing values array handling (NaN, NA, N/A, #N/A, :, -, TBA, TBD) - UseNoneForMissingValues flag behavior validation **Enhanced DateTime Conversions:** - Additional date format support - Microsoft JSON date format (/Date(timestamp)/) - Malformed date validation **Enhanced DateTimeOffset Conversions:** - Various timezone offset formats - Invalid input handling **New TimeSpan Conversions:** - Standard time formats (HH:MM:SS) - Days.Hours:Minutes:Seconds format - Whitespace handling - Invalid format detection **New Guid Conversions:** - Multiple GUID format support ({}, (), standard, no-dashes) - Case insensitivity validation - Whitespace trimming - Malformed GUID detection **New String Conversions:** - Option type behavior validation - Null/empty/whitespace handling **Edge Cases & Validation:** - Comprehensive currency symbol removal testing - Default missing values array validation - Whitespace and special character handling - Empty string and null input validation ## Test Results - **Total new tests added**: 14 test methods - **Total test count**: 2,268 → 2,282 tests (+14) - **All tests passing**: ✅ 2,282/2,282 - **Build status**: ✅ No compilation errors - **Code formatting**: ✅ Fantomas validation passed This improvement significantly strengthens the reliability of text conversion operations throughout the FSharp.Data library, providing comprehensive validation of data parsing and type conversion functionality. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
