+# Test Infrastructure for LLM.lang
+
+This document describes the test infrastructure that ensures sample code compiles and runs correctly.
+
+## Overview
+
+The test suite verifies that:
+1. Example .llm files can be compiled successfully
+2. Example .llm files can be executed without crashes
+3. CLI tools (llmc and llmi) work correctly with example files
+4. The entire toolchain works end-to-end
+
+## Important Note
+
+**To run the tests successfully, you need to use the `--no-default-features` flag to avoid heavy ML dependencies (PyTorch, etc.) that require external system libraries.**
+
+```bash
+cargo test --no-default-features
+```
+
+This disables features like `rust-bert`, `faiss`, and other ML libraries that require system dependencies to be installed.
+
+## Test Structure
+
+### Unit Tests (`src/`)
+- Located within the source files using `#[cfg(test)]`
+- Test individual components like lexer, parser, runtime, etc.
+- Run with: `cargo test --no-default-features --lib`
+
+### Integration Tests (`tests/`)
+
+#### `sample_code_tests.rs`
+Tests the core compilation and execution functionality:
+- **`test_compile_simple_examples`**: Verifies simple examples compile
+- **`test_execute_simple_examples`**: Verifies simple examples execute
+- **`test_compile_debug_example`**: Tests more complex example compilation
+- **`test_execute_debug_example`**: Tests complex example execution
+- **`test_all_examples_parse`**: Ensures all examples are syntactically valid
+- **`test_minimal_example`**: Tests a basic inline example
+
+#### `cli_integration_tests.rs`
+Tests the CLI tools:
+- **`test_llmi_simple_examples`**: Tests the interpreter with examples
+- **`test_llmc_simple_examples`**: Tests the compiler with examples
+- **`test_run_example_script`**: Tests the convenience script
+
+## Example Files Tested
+
+### Simple Examples (Must Pass)
+- `examples/simple_hello.llm` - Basic hello world
+- `examples/simple_print.llm` - Simple print statement
+- `examples/test.llm` - Minimal test
+- `examples/test_lexer.llm` - Lexer test
+
+### Complex Examples (May Fail Due to Unimplemented Features)
+- `examples/debug_test.llm` - Variables, conditionals, loops
+- `examples/hello_world.llm` - Full feature demonstration
+- `examples/llm_features.llm` - Advanced language features
+
+## Running Tests
+
+### All Tests
+```bash
+cargo test --no-default-features
+```
+
+### Sample Code Tests Only
+```bash
+cargo test --no-default-features sample_code_tests
+```
+
+### CLI Integration Tests Only
+```bash
+cargo test --no-default-features cli_integration_tests
+```
+
+### With Output
+```bash
+cargo test --no-default-features -- --nocapture
+```
+
+## Test Configuration
+
+### Dependencies
+The tests run with minimal dependencies by using `--no-default-features` to avoid heavy ML libraries that require external system dependencies.
+
+### Timeouts and Limits
+- Memory limit: 1MB for simple tests, 2MB for complex tests
+- Time limit: 5-10 seconds for execution
+- Compilation should complete quickly
+
+### Error Handling
+- Simple examples are expected to compile and run successfully
+- Complex examples may fail due to unimplemented features (acceptable for now)
+- CLI tools should produce meaningful output even on failure
+
+## Adding New Tests
+
+### For New Example Files
+1. Add the file path to the appropriate test array
+2. Specify expected behavior (compile, execute, or both)
+3. Consider adding it to CLI integration tests
+
+### For New Features
+1. Create unit tests in the relevant source files
+2. Add integration tests if the feature affects end-to-end functionality
+3. Update this documentation
+
+## Test Results Interpretation
+
+### Success Indicators
+- ✓ Test passes completely
+- Output shows meaningful execution results
+- No crashes or panics
+
+### Expected Failures
+- Complex features not yet implemented
+- Advanced language constructs (parallel, vectors, NLP)
+- File I/O and system interactions
+
+### Actual Failures
+- Simple examples failing to compile
+- Crashes during execution
+- CLI tools not producing any output
+
+## Future Improvements
+
+1. **Output Verification**: Capture and verify actual program output
+2. **Performance Tests**: Add benchmarks for compilation and execution speed
+3. **Error Message Quality**: Verify error messages are helpful
+4. **Cross-platform Testing**: Test on different operating systems
+5. **Continuous Integration**: Set up automated testing
