Testing WGSL Language Support and Tokenization in Monaco Editor

This test suite validates the tokenization and syntax highlighting functionality for WGSL (WebGPU Shading Language) in the Monaco Editor. It ensures proper parsing and display of WGSL code elements including keywords, operators, types, and language constructs.

Test Coverage Overview

The test suite provides comprehensive coverage of WGSL language features and syntax elements. Key areas tested include address spaces, attributes, block comments, boolean types, brackets, numeric constants, operators, predeclared types, reserved keywords, texture types, and basic shader structures.

  • Tests basic language constructs and tokenization
  • Validates syntax highlighting for all WGSL elements
  • Covers edge cases in parsing and token identification

Implementation Analysis

The implementation uses Monaco Editor’s tokenization framework to parse and highlight WGSL code. The test cases systematically verify token classification and coloring rules through detailed test vectors covering different syntax patterns and language features.

  • Token types include keywords, operators, identifiers, numbers, etc
  • Tests token boundaries and multi-token constructs
  • Validates proper nesting and scope handling

Technical Details

The test framework uses Monaco’s testTokenization utility to validate token classification. Each test case specifies input code and expected token sequences with their types and boundaries.

  • Uses ITestItem interface for test definitions
  • Validates token start indices and types
  • Tests proper handling of whitespace and delimiters

Best Practices Demonstrated

The test suite follows testing best practices including:

  • Comprehensive coverage of language features
  • Systematic organization of test cases
  • Clear separation of test categories
  • Detailed validation of tokenization rules
  • Edge case testing
