EB-8: Update test code for deprecated test annotations

Summary

This PR documents a critical blocker for ticket EB-8. After comprehensive investigation across all branches, I've determined that @MockBean and @SpyBean are NOT deprecated in Spring Boot 3.3.3. These annotations only become deprecated in Spring Boot 3.4.0+, and the replacement annotations do not exist in the current version.

Investigation Results

Comprehensive Search Performed

• ✅ Searched main branch (DevOps)
• ✅ Searched all test coverage branches
• ✅ Examined git history for annotation changes
• ✅ Checked build artifacts

Key Findings

Current State:

• Spring Boot Version: 3.3.3
• @MockBean Status: NOT deprecated ✅
• @SpyBean Status: NOT deprecated ✅

Required for Implementation:

• Spring Boot Version: 3.4.0+
• New annotations: @MockitoBean, @MockitoSpyBean (only available in 3.4+)
• Package: org.springframework.test.context.bean.override.mockito (doesn't exist in 3.3.3)

Annotation Locations Found

Branch	File	Annotation	Count
devin/1759413280-expand-test-coverage	src/test/java/com/example/bankapp/controller/BankControllerTest.java	@MockBean	1
devin/1759408856-mba-307-controller-tests	src/test/java/com/example/bankapp/controller/BankControllerTest.java	@MockBean	1

Blocker Status

This ticket is BLOCKED and cannot proceed until:

• ✅ EB-1: Spring Boot 3.4.9 Upgrade is completed

Why This Is Blocked

1. No Deprecation: The annotations to replace are not deprecated in Spring Boot 3.3.3
2. No Replacement: The new @MockitoBean and @MockitoSpyBean annotations don't exist in 3.3.3
3. Compilation Failure: Attempting to use the new annotations results in:

   package org.springframework.test.context.bean.override.mockito does not exist
   

4. Clean Migration Path: Waiting for 3.4+ upgrade ensures proper support

Documentation Added

This PR adds comprehensive blocker analysis documentation:

• File: EB-8-BLOCKER-ANALYSIS.md
• Contents:
  • Complete investigation methodology and results
  • Technical context on Spring Boot 3.4 bean override framework
  • Dependency chain visualization
  • Post-EB-1 action items

Recommendation

Immediate Actions:

1. Mark ticket EB-8 as BLOCKED
2. Add dependency on ticket EB-1 (Spring Boot 3.4.9 upgrade)
3. Revisit this ticket after EB-1 completion

Post-EB-1 Actions:

1. Verify Spring Boot version is 3.4.0+
2. Check for deprecation warnings
3. Perform annotation replacement
4. Estimated effort: ~30 minutes (2 story points)

Testing

• ✅ Current build compiles successfully with existing @MockBean annotations
• ✅ No deprecation warnings present in Spring Boot 3.3.3
• ✅ Documentation is comprehensive and actionable
