+# Testing Infrastructure
+
+This directory contains the test suite for the Video Super-Resolution project.
+
+## Structure
+
+```
+tests/
+├── __init__.py
+├── conftest.py          # Shared pytest fixtures
+├── unit/                # Unit tests
+│   └── __init__.py
+├── integration/         # Integration tests
+│   └── __init__.py
+└── test_infrastructure_validation.py  # Validation tests
+```
+
+## Running Tests
+
+```bash
+# Run all tests
+poetry run pytest
+
+# Run with coverage
+poetry run pytest --cov
+
+# Run specific test markers
+poetry run pytest -m unit        # Run only unit tests
+poetry run pytest -m integration # Run only integration tests
+poetry run pytest -m "not slow"  # Skip slow tests
+
+# Run tests in verbose mode
+poetry run pytest -v
+
+# Run a specific test file
+poetry run pytest tests/test_infrastructure_validation.py
+```
+
+## Writing Tests
+
+1. Place unit tests in `tests/unit/`
+2. Place integration tests in `tests/integration/`
+3. Use the fixtures defined in `conftest.py`
+4. Mark tests appropriately with `@pytest.mark.unit`, `@pytest.mark.integration`, or `@pytest.mark.slow`
+
+## Coverage
+
+Coverage reports are generated automatically when running tests:
+- HTML report: `htmlcov/index.html`
+- XML report: `coverage.xml`
+- Terminal report: Shown after test run
+
+The project is configured to require 80% code coverage.
