From 1d74d447b8034afaf973dea44d29f4b1f3134fe8 Mon Sep 17 00:00:00 2001 From: Simon Schrottner Date: Thu, 11 Sep 2025 08:46:28 +0200 Subject: [PATCH] feat: enhance evaluation context Gherkin tests with comprehensive spec coverage MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Expand contextMerging.feature to provide complete behavioral coverage of the 03-evaluation-context.md specification and rename to evaluation_context.feature to better reflect its comprehensive scope. ## Key Enhancements ### File Rename - Renamed contextMerging.feature → evaluation_context.feature - Better reflects comprehensive evaluation context coverage beyond just merging ### Unified Type-Aware Step Definitions - Standardized all context assertions to use unified pattern: `The merged context contains an entry with key "" and value "" of type ""` - Added explicit type validation to all existing context merging scenarios - Consolidated type checking into single, reusable step definition - Updated Given steps to include type specification for consistency ### Comprehensive Behavioral Coverage Added test scenarios for previously uncovered evaluation context requirements: **Context Field Requirements (3.1.x):** - 3.1.1: Optional targeting key field validation and optional nature - 3.1.2: Custom field type support (boolean, string, integer) - 3.1.3: Field access methods demonstrating retrieval capabilities - 3.1.4: Unique key enforcement through context precedence rules **Enhanced Context Merging (3.2.3):** - Added comprehensive tagging and specification references - Improved scenario descriptions for clarity - Maintained full precedence testing: API → Transaction → Client → Invocation → Before Hooks ### Implementation Optimizations - Maximized reuse of existing step definitions to minimize implementation overhead - Leveraged context merging precedence to demonstrate key uniqueness (3.1.4) - Used practical type mappings compatible with Java implementation: * number → integer for better type system compatibility * Focused on commonly implemented types (boolean, string, integer) - Removed redundant API availability tests in favor of behavioral validation ### Implicit Coverage Documentation Added comprehensive documentation explaining why certain specification requirements don't need dedicated test scenarios: **Context Paradigms (3.2.1.1, 3.2.2.1-2.4, 3.2.4.1-4.2):** - Dynamic/static paradigm method availability proven by successful context merging - Domain-specific context and change notifications are provider-level concerns - Architectural decisions don't require behavioral validation **Context Propagation (3.3.1.1, 3.3.1.2.1-2.3, 3.3.2.1):** - Transaction propagator management is API design, not behavior - Transaction context behavior already validated by @transaction merging tests - Implementation-specific propagation mechanisms vary by language/platform ### Enhanced Test Organization - Comprehensive tagging for selective test execution: * @context-fields, @context-merging, @context-precedence * @targeting-key, @custom-fields, @field-access, @unique-keys * Specification tags: @spec-3.1.1 through @spec-3.2.3 - Logical grouping of related scenarios - Clear separation between behavioral tests and implicit coverage ## Breaking Changes - File renamed: contextMerging.feature → evaluation_context.feature - Modified all existing context assertion steps to include type specification - Context paradigm and propagation scenarios removed (documented as implicit) - Requires step definition updates to handle `of type ""` parameter ## Testing Strategy The enhanced test suite validates core evaluation context behavior: 1. **Context Merging**: Precedence rules across all context levels 2. **Type Safety**: Explicit type validation for all context values 3. **Field Management**: Custom fields, targeting keys, and key uniqueness 4. **Practical Coverage**: Focus on implementable, testable behaviors This provides comprehensive validation of evaluation context functionality while eliminating redundant API availability tests and focusing on behavioral requirements that implementation teams actually need to validate. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- .../assets/gherkin/contextMerging.feature | 128 ----------- .../assets/gherkin/evaluation_context.feature | 200 ++++++++++++++++++ 2 files changed, 200 insertions(+), 128 deletions(-) delete mode 100644 specification/assets/gherkin/contextMerging.feature create mode 100644 specification/assets/gherkin/evaluation_context.feature diff --git a/specification/assets/gherkin/contextMerging.feature b/specification/assets/gherkin/contextMerging.feature deleted file mode 100644 index 7e84bffa..00000000 --- a/specification/assets/gherkin/contextMerging.feature +++ /dev/null @@ -1,128 +0,0 @@ -Feature: Context merging precedence -
