+# Week 10 Progress Report by Nikhil Bhatt
+
+**Project:** [Git backend for MusicBlocks](https://github.com/benikk/musicblocks-backend)  
+**Mentors:** [Walter Bender](https://github.com/walterbender), [Sumit Srivastava](https://github.com/sum2it)  
+**Reporting Period:** 2025-08-04 – 2025-08-10

+## This Week's Achievements
+
+###  Wrote Comprehensive Backend Tests with Jest
+This week, I focused heavily on **testing the backend** to ensure long-term stability and reliability.
+
+- Created **160 individual tests** ([view them here](https://github.com/BeNikk/musicblocks-backend/tree/main/tests)) covering core API functionality. 
+- Used **Jest** for the testing framework, along with **mocking controllers** to isolate logic from external dependencies.
+- Tests cover both **happy paths** and **edge cases**, ensuring robust API behavior.
+- This significantly improves our **confidence in future code changes** without fear of breaking existing features.
+
+###  Restructured and Improved APIs
+In parallel, I revisited some of our backend APIs for **better structuring and maintainability**.
+
+- Refactored route definitions for better **logical grouping**.
+- Improved **error handling** and **consistent response formats**.
+- Optimized certain request flows to reduce unnecessary API calls.
+
+---
+
+## Challenges & How I Solved Them
+
+- **Challenge:** Maintaining test isolation without hitting actual APIs or databases.  
+  **Solution:** Used Jest mocks and stubs for controllers, ensuring tests run quickly and independently.
+
+- **Challenge:** Some APIs had inconsistent parameter handling.  
+  **Solution:** Standardized parameter validation and request body structures.
+
+- **Challenge:** Structuring large test suites while keeping them readable.  
+  **Solution:** Organized tests by feature/module and used descriptive naming conventions.
+
+---
+
+## Key Learnings
+
+- Mastered advanced **Jest mocking** techniques for controller and service layer isolation.
+- Learned the importance of **test coverage as a safety net** for refactoring.
+- Refactoring APIs not only improves code quality but also helps onboarding new contributors.
+
+---
+
+## Next Week's Roadmap
+
+- Continue expanding test coverage to newly added backend features.
+- Start preparing **documentation** for the backend APIs.

+## Acknowledgments
+
+Thanks to my mentors and the Sugar Labs community for their support and feedback during the testing phase!  
+This week was a major milestone towards making the backend **production-ready**.  
+Looking forward to refining it even further next week.
