From 8b32a877cc2df1d5abfbce5a6b30f55ea7499c65 Mon Sep 17 00:00:00 2001 From: johndoe6345789 Date: Wed, 21 Jan 2026 03:06:27 +0000 Subject: [PATCH] feat: Add comprehensive test migration tooling MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add AST-based migration framework for converting TypeScript tests to JSON: New files: - scripts/migrate-tests/converter.ts (350+ lines) * AST parser for .test.ts files * Extracts describe/it/expect blocks * Maps 30+ Jest/Vitest matchers to JSON types * Returns structured ConversionResult - scripts/migrate-tests/migrator.ts (250+ lines) * Batch discovery and migration orchestrator * Glob-based .test.ts file discovery * Automatic output directory creation * Dry-run mode for safe preview * Pretty-printed progress reporting * Package name mapping (frontends → packages) - scripts/migrate-tests/validator.ts (300+ lines) * JSON schema validation using AJV * Semantic checks (unique IDs, assertions) * Unused import warnings * Directory-wide validation support * Structured ValidationResult output - scripts/migrate-tests/index.ts * Unified export module - scripts/migrate-tests/README.md * Comprehensive usage guide * Conversion process documentation * Matcher mapping reference * Workflow recommendations * Troubleshooting guide Features: * 80/20 conversion (handles ~80% of tests cleanly) * Fallback for complex tests requiring manual adjustment * Dry-run mode to preview changes * Verbose logging for troubleshooting * Validates against tests_schema.json Matcher Support: * Basic: equals, deepEquals, notEquals, truthy, falsy * Numeric: greaterThan, lessThan, greaterThanOrEqual, lessThanOrEqual * Type: null, notNull, undefined, notUndefined, instanceOf * Collection: contains, matches, hasProperty, hasLength * DOM: toBeVisible, toBeInTheDocument, toHaveTextContent, toHaveAttribute, toHaveClass, toBeDisabled, toBeEnabled, toHaveValue * Control: throws, notThrows, custom This completes Phase 3 Task 4 of the JSON interpreter everywhere implementation.
