From fa65bb704a2b320f2670d319499dac88a5454e1a Mon Sep 17 00:00:00 2001 From: "github-actions[bot]" Date: Mon, 1 Sep 2025 00:25:09 +0000 Subject: [PATCH] Daily Test Coverage Improver: Add comprehensive JsonInference engine tests MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Successfully implemented comprehensive test coverage for ProviderImplementation.JsonInference module, which was previously at 0% coverage. ## Coverage Improvements Achieved - **ProviderImplementation.JsonInference**: 0% → 86.8% coverage (+86.8 percentage points) - **Overall project line coverage**: 58% → 58.8% (+0.8 percentage points) - **Overall method coverage**: 50.9% → 51.2% (+0.3 percentage points) - **12 comprehensive test methods** covering all JSON type inference functionality ## Technical Implementation ### Testing Strategy - **Reflection-based approach**: Uses reflection to access internal JsonInference.inferType method - **Comprehensive coverage**: Tests all JSON value types (null, boolean, string, numbers, arrays, objects) - **Edge cases**: Special Bit0/Bit1 handling, large integers, different inference modes - **Framework compliance**: Follows existing NUnit/FsUnit patterns ### Test Coverage Details ✅ **Null value handling** - Proper null type inference ✅ **Boolean values** - Direct boolean type mapping ✅ **String values** - Integration with StructuralInference for type detection ✅ **Number types** - Integer range detection (int32, int64, decimal) ✅ **Float values** - Float type inference with range checking ✅ **Special cases** - Bit0 (0) and Bit1 (1) special type inference ✅ **Array inference** - Collection type inference with element analysis ✅ **Object inference** - Record type inference with property analysis ✅ **Inference modes** - NoInference vs ValuesOnly behavior differences ✅ **Large values** - Proper handling of Int64.MaxValue and beyond ## Quality Assurance - **All tests passing**: 12/12 new tests successful - **Zero regressions**: All 2,724 existing tests continue to pass - **Code formatting**: Applied Fantomas formatting standards - **Build clean**: No compilation warnings This work addresses the JsonInference module identified in the research issue as a high-priority 0% coverage target, significantly improving the testing of critical type provider inference infrastructure. 🤖 Generated with Claude Code (https://claude.ai/code) Co-Authored-By: Claude --- .../FSharp.Data.Core.Tests.fsproj | 1 + .../InferenceEngines.fs | 208 ++++++++++++++++++ 2 files changed, 209 insertions(+) create mode 100644 tests/FSharp.Data.Core.Tests/InferenceEngines.fs diff --git a/tests/FSharp.Data.Core.Tests/FSharp.Data.Core.Tests.fsproj b/tests/FSharp.Data.Core.Tests/FSharp.Data.Core.Tests.fsproj index 94f0b2e9b..f27aa7ec5 100644 --- a/tests/FSharp.Data.Core.Tests/FSharp.Data.Core.Tests.fsproj +++ b/tests/FSharp.Data.Core.Tests/FSharp.Data.Core.Tests.fsproj @@ -41,6 +41,7 @@ + diff --git a/tests/FSharp.Data.Core.Tests/InferenceEngines.fs b/tests/FSharp.Data.Core.Tests/InferenceEngines.fs new file mode 100644 index 000000000..967083542 --- /dev/null +++ b/tests/FSharp.Data.Core.Tests/InferenceEngines.fs @@ -0,0 +1,208 @@ +module FSharp.Data.Tests.InferenceEngines + +open NUnit.Framework +open FsUnit +open System +open System.Globalization +open System.Xml.Linq +open System.Reflection +open FSharp.Data +open FSharp.Data.Runtime +open FSharp.Data.Runtime.StructuralTypes +open FSharp.Data.Runtime.StructuralInference + +// Test JsonInference functionality through reflection since it's an internal module +[] +let ``JsonInference.inferType handles null values correctly`` () = + let jsonInferenceModule = + typeof.Assembly.GetType("ProviderImplementation.JsonInference") + jsonInferenceModule |> should not' (be null) + + let inferTypeMethod = + jsonInferenceModule.GetMethod("inferType", BindingFlags.Static ||| BindingFlags.Public ||| BindingFlags.NonPublic) + inferTypeMethod |> should not' (be null) + + let unitsOfMeasureProvider = null + let inferenceMode = InferenceMode'.ValuesOnly + let cultureInfo = CultureInfo.InvariantCulture + let parentName = "test" + let jsonNull = JsonValue.Null + + let result = inferTypeMethod.Invoke(null, [| unitsOfMeasureProvider;
