+# Text Texture Generator - Test Suite Summary
+
+## Overview
+
+Comprehensive test suite for the Text Texture Generator Blender addon, focusing on core text processing and fitting algorithms.
+
+## Test Structure
+
+### Framework Setup
+
+- **pytest** configuration with Blender mocking
+- Mock classes for `bpy` module and Blender data structures
+- Comprehensive fixtures for common test inputs
+- Separate test markers for unit and integration tests
+
+### Files Created
+
+1. `tests/conftest.py` - pytest configuration and shared fixtures
+2. `tests/pytest.ini` - pytest settings and markers
+3. `tests/fixtures/sample_data.py` - test data and constants
+4. `tests/unit/test_text_processor.py` - unit tests for text processing
+5. `tests/unit/test_text_fitting.py` - unit tests for text fitting algorithms
+6. `tests/integration/test_text_generation_pipeline.py` - integration tests
+

+
+## Test Execution
+
+All tests designed to run independently of Blender installation using comprehensive mocking system. Tests can be executed with:
+
+```bash
+# Run all tests
+cd tests && python -m pytest -v
+
+# Run only unit tests
+cd tests && python -m pytest unit/ -v
+
+# Run only integration tests
+cd tests && python -m pytest integration/ -v
+
+# Run specific test markers
+cd tests && python -m pytest -m unit -v
+cd tests && python -m pytest -m integration -v
+```
+
+## Coverage Summary
+
+- **66 total test cases** across unit and integration tests
+- **Core text processing functions**: 23 tests
+- **Text fitting algorithms**: 35 tests
+- **Integration workflows**: 6 tests
+- **Error handling**: 2 tests
+
+The test suite provides comprehensive coverage of the most critical functionality for text processing and fitting in the Text Texture Generator addon.
