charset=UTF-8 Content-Transfer-Encoding: 8bit Added comprehensive test coverage for all Platform.Numbers functionality: - **New MathTests.cs**: Complete test coverage for Math class - Factorial function tests with valid inputs (0-20) and boundary cases - Catalan number tests with valid inputs (0-36) and boundary cases - IsPowerOfTwo tests covering edge cases and comprehensive range - Generic type tests for all three Math methods - Tests for maximum constant values - **Enhanced BitTests.cs**: Added missing test coverage for Bit class - Complete test coverage for Bit.Count method (previously untested) - Tests for negative shift and limit parameters in Bit operations - Round-trip tests for PartialWrite/PartialRead operations - Tests with different numeric types (byte, ushort, uint, ulong) - **Bug Fix**: Fixed incorrect bounds check in Math.Factorial method - Changed from MaximumCatalanIndex to MaximumFactorialNumber - Ensures proper argument validation for factorial calculations **Test Coverage Results:** - Line Coverage: 98.76% (increased from 39.5%) - Branch Coverage: 90.9% (increased from 45.45%) - Total Tests: 76 (increased from 7) - All tests passing 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- csharp/Platform.Numbers.Tests/BitTests.cs | 117 +++++++++++++++++++++ csharp/Platform.Numbers.Tests/MathTests.cs | 111 +++++++++++++++++++ csharp/Platform.Numbers/Math.cs | 2 +- 3 files changed, 229 insertions(+), 1 deletion(-) create mode 100644 csharp/Platform.Numbers.Tests/MathTests.cs diff --git a/csharp/Platform.Numbers.Tests/BitTests.cs b/csharp/Platform.Numbers.Tests/BitTests.cs index 3a3079b..fc4a5ce 100644 --- a/csharp/Platform.Numbers.Tests/BitTests.cs +++ b/csharp/Platform.Numbers.Tests/BitTests.cs @@ -173,5 +173,122 @@ public static void BugWithLoadingConstantOf8Test() { Bit.PartialWrite(0, 1, 5, -5);
