Test Suite Generation

Generate Financial Transaction Scenarios Automatically

Create banking-specific test suites that cover transactions, fraud checks, and escalation workflows with production realism.

Generate Financial Transaction Scenarios Automatically illustration

Test End-to-End Transaction Processing

  • Test transfers, payments, and refund processes from initiation to confirmation
  • Validate amount confirmation, recipient verification, and transaction authorization
  • Validate secure DTMF handoffs and payment redirections during sensitive data entry

Validate Authentication and Data Security Flows

  • Test multi-factor authentication using PINs, OTPs, and security questions
  • Validate secure credential handling and encryption across sessions
  • Ensure secure handling of failed authentication attempts and secure session handling for sensitive customer data

Test Fraud Detection and Prevention Capabilities

  • Simulate fraud scenarios like social engineering or unauthorized access attempts
  • Test alert generation, transaction blocking, and escalation workflows
  • Confirm accurate handling and traceability of fraud-related interactions

AI Voice Agent Testing

Catch Hallucinations and Compliance Drift

Test across thousands of banking scenarios to validate transaction accuracy, compliance adherence, and model reliability across financial workflows.

Catch Hallucinations and Compliance Drift illustration

Ensure Financial Regulatory Compliance

  • Test compliance with PCI DSS, GDPR, and regional financial data laws
  • Validate required disclosures, consent collection, and opt-in/opt-out handling
  • Ensure compliant recording notices and customer authorization workflows

Test Account Management and Servicing

  • Test balance inquiries, transaction lookups, and account modifications
  • Validate address changes, card replacements, and service requests
  • Ensure accurate fee and interest rate disclosures

Red Team Financial Voice Agents

  • Simulate jailbreaks, data extraction, and prompt manipulation attempts
  • Test agent resilience under noise, code-switching, and cross-talk conditions
  • Validate safeguards that prevent sensitive data disclosure and policy violations

Operational Reliability Testing

Operational Reliability for Financial Voice Models

Continuously validate production voice agents for compliance, accuracy, and performance as prompts and models evolve.

Operational Reliability for Financial Voice Models illustration

Monitor Ongoing Compliance in Production

  • Monitor real-time compliance with data handling and privacy regulations
  • Track consent collection, opt-in/opt-out handling, and disclosure accuracy
  • Generate compliance reports and audit trails for regulatory review

Detect Model Drift and Performance Degradation

  • Monitor transaction accuracy, authentication success rates, and fraud detection performance
  • Detect prompt regressions that could cause compliance violations
  • Alert on unexpected changes in customer interaction patterns or response quality

Pre-Production Model Validation

  • Evaluate new model versions against live traffic patterns
  • Compare accuracy, latency, and compliance metrics across versions
  • Maintain workflow integrity for authentication, payments, and servicing
  • Identify regressions or compliance risks in production

Frequently Asked Questions

Answers to common questions teams ask when testing voice agents.

Yes. Hamming tests multi-factor authentication and data-handling flows to ensure secure account access and processing. We simulate PIN entry, OTP verification, security questions, and failed authentication scenarios.

Hamming validates that your voice agent never stores, displays, or transmits full card numbers inappropriately. We test secure payment collection, tokenization, DTMF handoffs, and PCI-compliant handling of cardholder data.

Absolutely. Hamming simulates suspicious transaction patterns and validates that your voice agent detects anomalies, triggers alerts, and follows proper verification protocols before approving high-risk transactions.

Select a testing platform that covers three key areas: security (authentication, PCI DSS compliance, fraud detection), regulatory adherence (GDPR, data privacy, disclosure handling), and operational reliability. Hamming automates all three with pre-built scenarios tailored to financial services workflows.

Setup takes about 10 minutes—we pull your agent configuration via API and auto-generate test scenarios specific to your workflows. You'll be running your first batch of tests in under 10 minutes.

Yes. We test the full range of account servicing: balance inquiries, transaction history lookups, fund transfers, bill payments, card replacements, and address changes. We validate that amounts and account details are captured accurately.

Hamming includes red teaming capabilities that simulate jailbreaks, data extraction attempts, and prompt manipulation. We test agent resilience under adversarial conditions and validate safeguards that prevent sensitive data disclosure.

Yes. Hamming runs batch testing with 10, 20, 50, or 100+ simultaneous test calls. This is critical for validating performance under peak conditions like market opens, end-of-month processing, or promotional campaigns.
