+# Lab 03
+
+## Testing
+
+### Choosing Test Framework
+
+I chose pytest as test framework for some reasons:
+
+- It supports different kind of tests
+- It has simple syntax
+- It supports powerfull fixtures
+- It has rich plugin architecture
+
+### Tests Structure
+
+File `test_endpoints.py` consists of 3 test functions:
+
+- `test_root()` verifies status code, structure, and fields of request to `/`
+- `test_health()` verifies status code, structure and fields of request to `/health`
+- `test_404()` verifies status code of request to not existing path
+
+### Tests Terminal Output
+
+```bash
+$ pytest tests/
+========================= test session starts =========================
+platform win32 -- Python 3.14.0, pytest-9.0.2, pluggy-1.6.0
+rootdir: C:\DevOps\app_python
+plugins: anyio-4.12.1
+collected 3 items
+
+tests\test_endpoints.py ...                                      [100%]
+
+========================== 3 passed in 0.54s ==========================
+```
+
+## Actions Workflow
+
+### Workflow Trigger Strategy
+
+Workflow triggers on opening (or reopening) pull requests to master, since we need to check code before merging.
+
+### Action Choice
+
+I chose official GitHub and Docker actions, since they are trustworthy.
+
+### Docker Tagging Strategy
+
+Fro tagging I have used current date, since it is enough for version tracking.
+
+### Proofs
+
+Link to successful workflow: <https://github.com/KOSMOGOR/DevOps-Core-Course/actions/runs/21801589090>
+
+Screenshot:
+
+![Workflow](./screenshots/lab03/successful-actions-workflow.png)
+
+## Continious Integration
+
+### Successful working badge
+
+![badge](/docs/screenshots/lab03/successful-actions-badge.png)
+
+### Caching Implemantation
+
+Caching was implemented using `cache: pip`
+
+### Best Practices
+
+I used practices like:
+
+- Optimize pipeline stages - I optimized pipeline stages
+- Use failures to improve processes - tasks can fail due to not compliting some requirements
+- Use secrets - I used GitHub secrets for tokens in workflow
+
+### Snyk Integration Results
+
+Snyk found vulnarability in package `python-multipart` and suggested upgrading it, and I have done it.
