Test Suite Generation

Generate Restaurant Order Scenarios Automatically

Create comprehensive test suites that cover menu orders, customizations, and edge cases specific to quick service restaurants.

Generate Restaurant Order Scenarios Automatically illustration

Test Complex Menu Orders and Customizations

  • Test menu item variations ('no pickles', 'extra cheese', 'light ice')
  • Validate combo meal modifications and upsell suggestions
  • Ensure accurate capture of size changes, meal swaps, and dietary restrictions

Validate Order Modification and Correction Flows

  • Simulate customers changing their mind mid-order ('Actually, make that a large')
  • Test correction flows when orders are misheard or misunderstood
  • Validate cart modification scenarios (add, remove, change items)

Test in Real Drive-Thru Conditions

  • Simulate drive-thru environments (engine noise, wind, speaker distortion)
  • Test with background passengers, music, and multi-speaker scenarios
  • Validate order accuracy despite poor audio quality and interruptions

AI Voice Agent Testing

Comprehensive QSR Voice Agent Validation

Save hours by automating QSR voice agent testing across thousands of ordering scenarios to catch issues before they reach customers.

Validate Upsell and Promotional Offer Flows

  • Test upsell suggestions ('Would you like fries with that?') at appropriate moments
  • Validate promotional code application and combo meal recommendations
  • Ensure price accuracy for modified orders and special offers

Ensure Order and Payment Accuracy

  • Test order total calculations with modifications and promotions
  • Validate payment method capture and PCI-compliant handling
  • Ensure accurate order confirmation and readback to customers

Prevent Performance Degradation During Rush Hours

  • Monitor order accuracy degradation under concurrent call load
  • Identify latency spikes that slow down drive-thru and phone ordering
  • Catch breaking changes from menu updates or POS system modifications

Concurrency Load Testing

QSR Load Testing & Peak Volume Simulation

Simulate high-volume ordering scenarios to ensure your voice agents maintain performance during lunch rush, dinner rush, and promotional campaigns.

Realistic test scenarios

  • Simulate natural conversation patterns and customer behaviors
  • Generate diverse customer personas with communication styles
  • Create edge cases and challenging scenarios automatically

Multilingual testing

  • Generate test cases in multiple languages and regional variations
  • Test handling of code-switching and mixed language conversations
  • Validate pronunciation and understanding with different accents

Noise simulation

  • Simulate common background noises like traffic, crowds, or music
  • Validate agent performance with varying noise levels and types
  • Test noise cancellation and speech recognition in challenging conditions

Frequently Asked Questions

Answers to common questions teams ask when testing voice agents.

Yes. Hamming simulates realistic drive-thru environments including engine noise, wind, speaker distortion, and background passengers. We test how your voice agent performs under actual acoustic conditions to ensure order accuracy.

Hamming creates test scenarios covering common modifications ('no pickles', 'extra cheese', 'light ice') and validates that your voice agent captures, confirms, and processes them correctly. We test substitutions, additions, and complex combo modifications.

Absolutely. Hamming simulates realistic ordering scenarios that trigger POS integration, order creation, and payment processing. We validate data accuracy, handle error scenarios (POS downtime), and measure integration latency.

Hamming simulates lunch rush, dinner rush, and game day volumes with 50-100+ concurrent calls. We monitor order accuracy, latency, and system stability under heavy load to ensure your voice agent maintains performance when it matters most.

Yes. Hamming lets you create test scenarios for new promotions, limited-time offers, and seasonal menu items. We validate that pricing, availability, and upsell logic work correctly before customers interact with them.

Yes. We support testing in Spanish, French, and 65+ other languages. We validate that your voice agent handles bilingual customers and regional accents common in QSR environments.

We create test scenarios for allergy inquiries (gluten-free, nut allergies, dairy-free) and validate that your voice agent provides accurate ingredient information and handles substitution requests correctly.

Yes. We test voice agents across different franchise configurations to ensure consistent customer experience, accurate local menu items, and proper handling of location-specific promotions.
