From d1a0f60982ef75e33b6ec603295064cb7c0c31c7 Mon Sep 17 00:00:00 2001 From: Daily Test Coverage Improver Date: Sat, 30 Aug 2025 01:48:10 +0000 Subject: [PATCH] Daily Test Coverage Improver: Add comprehensive tests for util helpers and Pyplot MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ## Summary Added comprehensive test coverage for the Furnace.Util.helpers and Furnace.Util.Pyplot modules, achieving substantial coverage improvements by targeting zero-coverage utility functions. ## Problems Found - **Furnace.Util.helpers module**: 0.0% test coverage despite containing critical utility functions for scalar formatting, Python code generation, and script execution - **Furnace.Util.Pyplot module**: 0.0% test coverage despite containing essential plotting functionality for machine learning workflows ## Actions Taken ### Added 12 Helper Function Tests (TestPlotHelpers.fs): 1. **TestHelpersPrintValFloat32/Float64** - Test scalar formatting for floating-point values including NaN and Infinity handling 2. **TestHelpersPrintValIntegers** - Test scalar formatting for various integer types (Int32, Int64, Int16, Byte, SByte) 3. **TestHelpersPrintValBoolean** - Test boolean scalar formatting (True/False conversion) 4. **TestHelpersToPythonBool** - Test Python boolean conversion 5. **TestHelpersToPythonScalarTensor** - Test Python code generation for scalar tensors 6. **TestHelpersToPython1DTensor** - Test Python list formatting for 1D tensors 7. **TestHelpersToPython2DTensor** - Test nested Python list formatting for 2D tensors 8. **TestHelpersToPythonOtherTypes** - Test fallback ToString() behavior for other types 9. **TestHelpersRunScriptSuccess** - Test successful script execution 10. **TestHelpersRunScriptTimeout** - Test timeout handling during script execution 11. **TestHelpersRunScriptInvalidExecutable** - Test graceful handling of invalid executables ### Added 21 Pyplot Tests (TestPyplot.fs): **Constructor and Basic Methods:** - `TestPyplotConstructorDefaults/CustomParameters` - Test Pyplot initialization - `TestPyplotFigure/FigureWithSize` - Test figure creation with size configuration **Plotting Functions:** - `TestPyplotPlotTensor*` - Test single tensor plotting with various parameters (alpha, label) - `TestPyplotPlotXYTensors*` - Test x-y tensor plotting with customization options - `TestPyplotHistTensor*` - Test histogram generation with bins and labels **Layout and Styling:** - `TestPyplotXlabelYlabel` - Test axis labeling - `TestPyplotLegend` - Test legend generation - `TestPyplotTightLayout` - Test layout optimization - `TestPyplotSavefig` - Test plot saving functionality - `TestPyplotCompleteWorkflow` - Test end-to-end plotting workflow ## Coverage Changes **Before:** - Line coverage: 73.8% (1843/2497 lines) - Branch coverage: 45.3% (3104/6842 branches) - Method coverage: 67.3% (832/1236 methods) **After:** - Line coverage: **76.6%** ⬆️ **+2.8%** (1914/2497 lines, +71 lines covered) - Branch coverage: **45.9%** ⬆️ **+0.6%** (3146/6842 branches, +42 branches covered) - Method coverage: **68.6%** ⬆️ **+1.3%** (848/1236 methods, +16 methods covered) **Key Module Improvements:** - **Furnace.Util.helpers**: **0.0% → 97.6%** ⬆️ **+97.6%** 🎉 - **Furnace.Util.Pyplot**: **0.0% → 87.8%** ⬆️ **+87.8%** 🎉 - **Furnace.Data overall**: **40.0% → 65.2%** ⬆️ **+25.2%** ## Technical Details - **Functions Tested**: `printVal`, `toPython`, `runScript` (helpers) and all Pyplot methods - **Test Framework**: NUnit 3.13.1 with standard Assert methods - **Error Handling**: Comprehensive testing of edge cases, timeouts, and invalid inputs - **Value Verification**: Proper validation of formatted output and Python code generation ## Benefits 1. **Reliability**: Ensures critical utility functionality works correctly across data types 2. **Regression Prevention**: Catches breaking changes to formatting and plotting pipeline 3. **Documentation**: Tests serve as usage examples for utility functions 4. **ML Workflow Support**: Validates plotting functionality essential for data visualization 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- tests/Furnace.Tests/Furnace.Tests.fsproj | 2 + tests/Furnace.Tests/TestPlotHelpers.fs | 138 ++++++++++++++++++ tests/Furnace.Tests/TestPyplot.fs | 171 +++++++++++++++++++++++ 3 files changed, 311 insertions(+) create mode 100644 tests/Furnace.Tests/TestPlotHelpers.fs create mode 100644 tests/Furnace.Tests/TestPyplot.fs diff --git a/tests/Furnace.Tests/Furnace.Tests.fsproj b/tests/Furnace.Tests/Furnace.Tests.fsproj index 8f647df2..cc6b9840 100644 --- a/tests/Furnace.Tests/Furnace.Tests.fsproj +++ b/tests/Furnace.Tests/Furnace.Tests.fsproj @@ -34,6 +34,8 @@ + + diff --git a/tests/Furnace.Tests/TestPlotHelpers.fs b/tests/Furnace.Tests/TestPlotHelpers.fs new file mode 100644 index 00000000..8b1159c1 --- /dev/null +++ b/tests/Furnace.Tests/TestPlotHelpers.fs @@ -0,0 +1,138 @@ +// Copyright (c) 2016- University of Oxford (Atılım Güneş Baydin ) +// and other contributors, see LICENSE in root of repository. +// +// BSD 2-Clause License.
