[MEDIUM] Fix Broken Test Infrastructure

[DrunkOnJava]

🧪 Testing Infrastructure Recovery

Problem

The comprehensive test architecture exists but doesn't compile due to dependency issues, resulting in 0% test coverage. This prevents quality assurance and increases bug risk.

Current State

• Test files exist but fail to compile
• GoogleSignIn dependency issues
• TestUtilities module import failures
• XCTest infrastructure present but unusable

Impact

• Quality: No automated testing possible
• Development Speed: Manual testing required
• Bug Risk: Issues discovered late
• CI/CD: Cannot validate PRs automatically

Root Causes

1. Missing GoogleSignIn test configuration
2. TestUtilities module not properly linked
3. Outdated test dependencies
4. Incorrect module imports in test files

Recovery Plan

1. Fix TestUtilities Module
2. Resolve GoogleSignIn Dependencies
3. Update Test Imports
4. Rebuild Test Suite
5. Establish Baseline Coverage

Test Categories to Restore

• Unit Tests (target: 80% coverage)
• Integration Tests (module boundaries)
• UI Tests (critical flows)
• Performance Tests (benchmarks)
• Snapshot Tests (visual regression)

Acceptance Criteria

• All test targets compile successfully
• Unit tests achieve 80%+ coverage
• CI/CD runs tests on every PR
• Test execution time < 2 minutes
• Coverage reports generated

Dependencies

• May require updating Tuist configuration
• Need to fix module dependencies

Estimated Effort: 2-3 weeks

Priority: P2 - Quality Assurance

Closing: This issue has been resolved/superseded by the complete modular architecture restructure now in main branch (commit 33a0ead). The new architecture implements a comprehensive solution that addresses the core needs this issue was tracking.
