From 52e2e929ef5462672b65d2111274600bb72429bb Mon Sep 17 00:00:00 2001 From: Daily Test Coverage Improver Date: Sun, 31 Aug 2025 21:56:45 +0000 Subject: [PATCH] Add comprehensive test coverage for JSON Runtime Helpers and BaseTypes.HtmlDocument MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This commit significantly improves test coverage for two previously untested areas: **JSON Runtime Helpers (FSharp.Data.Json.Core)** - Added 5 comprehensive test methods targeting the private Helpers module - Tests exercise edge cases for inRangeDecimal, inRangeFloat, isIntegerDecimal, and isIntegerFloat functions - Coverage includes boundary value testing for Int32/Int64 ranges - Tests integer detection for both decimal and float values - Added floating-point precision and special value handling (NaN, infinity) **BaseTypes.HtmlDocument (FSharp.Data.Html.Core)** - Created new test file with 16 comprehensive test methods - Tests all HtmlDocument class methods: Create, Html property, GetTable, GetList, GetDefinitionList - Coverage includes error handling, malformed HTML parsing, multiple elements - Tests both includeLayoutTables true/false scenarios - Added exception testing for missing elements **Test Framework Integration** - All tests use NUnit framework with FsUnit assertions - Tests follow existing project patterns and conventions - Added appropriate compiler warnings suppression for BaseTypes methods - All tests pass successfully with proper F# type safety **Coverage Impact** - Baseline: 42.6% overall line coverage - Target areas previously had 0% coverage - New tests provide comprehensive edge case and error condition coverage 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- .../BaseTypesHtmlDocument.fs | 258 ++++++++++++++++++ .../FSharp.Data.Core.Tests.fsproj | 1 + .../FSharp.Data.Core.Tests/JsonConversions.fs | 94 +++++++ 3 files changed, 353 insertions(+) create mode 100644 tests/FSharp.Data.Core.Tests/BaseTypesHtmlDocument.fs diff --git a/tests/FSharp.Data.Core.Tests/BaseTypesHtmlDocument.fs b/tests/FSharp.Data.Core.Tests/BaseTypesHtmlDocument.fs new file mode 100644 index 000000000..e2ee8c458 --- /dev/null +++ b/tests/FSharp.Data.Core.Tests/BaseTypesHtmlDocument.fs @@ -0,0 +1,258 @@ +module FSharp.Data.Tests.BaseTypesHtmlDocument + +open System.IO +open NUnit.Framework +open FsUnit +open FSharp.Data +open FSharp.Data.Runtime.BaseTypes + +#nowarn "10001" // Suppress "intended for use in generated code only" warnings + +[] +let ``HtmlDocument.Create successfully parses HTML with tables`` () = + let htmlContent = """ + + + + + +
