# CI Pipeline Failure Analysis
 
**Pipeline:** #12345
**Branch:** feature/new-checkout
**Commit:** abc1234
**Failed Job:** test-unit
**Duration:** 5m 32s
 
## Failure Summary
 
| Category | Count | Severity |
|----------|-------|----------|
| Test Failures | 3 | 🔴 Critical |
| PHPStan Errors | 0 | - |
| Infrastructure | 0 | - |
 
## Root Cause Analysis
 
### Primary Failure: Test Assertion Error
 
**Test:** `OrderTest::test_calculate_total_with_discount`
**File:** `tests/Unit/Domain/OrderTest.php:45`
 
**Error:**

 
**Analysis:**
The test expects an integer `90` but receives a float `90.0`. This is likely due to:
1. Changed calculation in `Order::calculateTotal()` now returns float
2. Test assertion uses strict comparison
 
**Suggested Fix:**

 
### Secondary Failure: Mock Configuration
 
**Test:** `PaymentServiceTest::test_process_payment`
**File:** `tests/Unit/Application/PaymentServiceTest.php:78`
 
**Error:**

 
**Analysis:**
Mock expectation not met. The `charge` method was never called, indicating:
1. Conditional logic preventing the call
2. Early return before reaching the charge
3. Exception thrown before charge
 
**Suggested Fix:**
Review the test setup and ensure conditions are met for `charge` to be called.
 
## Timeline
 

 
## Recommendations
 
1. **Immediate:** Fix type mismatch in OrderTest
2. **Short-term:** Add type declarations to prevent float/int confusion
3. **Long-term:** Use Money value object for financial calculations
 
## Related Changes
 
Recent commits that may have caused this failure:
- `abc1234` - Refactor calculateTotal to return float
- `def5678` - Update discount calculation logic
