• MEDIUM - Re-calculation overhead
• Issue: Some expensive operations not marked with #[Computed] attribute
• Fix: Use computed properties for expensive calculations

8.11-8.12 Missing Query Limits

• LOW - Potential large data sets
• Issue: Some queries lack limits (e.g., contract list, invoice list)
• Fix: Add consistent limits or pagination

Performance Strengths ✅

• ✅ Excellent database indexing - 20+ indexes on tickets, 13 on invoices, comprehensive coverage
• ✅ Good use of eager loading with with() in many places
• ✅ TeamPerformance widget shows proper caching pattern

• Issue: All tests use database (integration tests, not unit tests)
• Missing: 9 models without any tests
• Fix: Keep coverage, but true unit tests needed for business logic

Testing Antipatterns

10.8 Unit Tests Using Database - 100%

• HIGH - Not true unit tests
• Issue: ALL "unit tests" use RefreshDatabase trait
• Impact: Slow execution, brittle tests
• Fix: Use mocks/stubs for true unit testing

10.9 Weak Assertions

• MEDIUM - Low test value
• Examples:
  • Tests only check assertIsArray() without verifying content
  • Tests only check assertInstanceOf() without behavior
  • Tests only check fillable attributes exist
• Fix: Test behavior, not implementation

10.10 Missing Edge Case Tests

• HIGH - Incomplete coverage
• Missing tests for:
  • Negative amounts, null values
  • Invalid status transitions
  • Concurrent operations
  • Division by zero
  • Date boundaries
  • Very large values
  • Duplicate submissions
  • Race conditions
• Fix: Add edge case test suites

Summary Statistics

• Test/Code Ratio: 11.7% (121 tests for 1,036 files)
• Service Coverage: 3% (7/216)
• Controller Coverage: 4% (7/163)
• Livewire Coverage: 4% (5/120)
• Model Coverage: 91% (93/102)
• True Unit Tests: <1% (most use database)
