Test Infrastructure

Test Data Files

Tests use .kt files in testData/ directories with special directive comments:

// FILE: fileName.kt           - Split test into multiple files
// MODULE: moduleName          - Define module boundaries
// MODULE: name(dep1, dep2)    - Module with dependencies

// Common directives for language features and compiler options
// LANGUAGE: +Feature          - Enable language feature
// API_VERSION: 1.9            - Set API version
// WITH_STDLIB                 - Include stdlib in compilation

Test Generation

Tests are generated from abstract test runners. After adding test data:

1. Add test data file to appropriate testData/ directory
2. Run ./gradlew generateTests
3. New test methods appear in *Generated.java files in tests-gen/
