    • Status: ✅ PASSED

  2. Confirmation Modal Shows Correct Data

    • Modal displays correct amount
    • Balance check happens before modal opens
    • No error modals for valid payments
    • Status: ✅ PASSED

  3. Success Modal Displays Properly

    • Payment saved to database
    • FromAccount balance updated
    • Success modal shows transaction details
    • Status: ✅ PASSED

    • ToAccount cleared (new recipient needed)
    • Status: ✅ PASSED

  6. Form Auto-Submission Prevention

    • Confirmation modal ignores submission while success modal open
    • Old form data not resubmitted
    • Log: [CONFIRM-MODAL] Ignored (success modal already open)
    • Status: ✅ PASSED

✅ Security Attack Tests (5 attacks blocked)

Attack 1: Negative Amount Injection

Livewire.find('pay-component-id').set('amount', -50);
  • Expected: Blocked
  • Result: ✅ BLOCKED
  • Log: [TRANSFER] Security: Invalid payment amount (must be positive number)
  • Code:
if (!is_numeric($amount) || $amount <= 0) {
    return $this->logAndReport('Security: Invalid payment amount...');
}

Attack 2: Zero Amount Injection

Livewire.find('pay-component-id').set('amount', 0);
  • Expected: Blocked
  • Result: ✅ BLOCKED
  • Log: [TRANSFER] Security: Invalid payment amount (must be positive number)
  • Same validation as Attack 1

Attack 3: Invalid ToAccountId Injection

Livewire.find('pay-component-id').set('toAccountId', -1);
  • Expected: Blocked
  • Result: ✅ BLOCKED
  • Log: [TRANSFER] Security: Invalid To account ID
  • Code:
if (!is_int($toAccountId) || $toAccountId <= 0) {
    return $this->logAndReport('Security: Invalid To account ID...');
}

Attack 4: Unauthorized Account Access

  • Scenario: User A logged in, attempt to send from User B's account
  • Expected: Blocked
  • Result: ✅ BLOCKED
  • Log: [TRANSFER] Unauthorized payment attempt: illegal access of From account
  • Protection: Backend ownership check via getAccountsInfo()
$accountsInfo = collect($transactionController->getAccountsInfo());
if (!$accountsInfo->contains('id', $fromAccountId)) {
    return $this->logAndReport('Unauthorized payment attempt: illegal access...');
}

Attack 5: Balance Limit Bypass via Modal Manipulation

// Try to bypass limit check by modifying modal state
Livewire.find('pay-component-id').set('isPaymentLimitErrorModalOpen', false);
// Then send payment exceeding limits
  • Expected: Blocked
  • Result: ✅ BLOCKED
  • Log: [TRANSFER] Security: Payment attempt with exceeded balance limits detected
  • Code:
$limitsOk = $this->checkBalanceLimits(...);
if (!$limitsOk) {
    return; // Execution stops regardless of modal state
}
