Frequently Asked Questions

Agent to Agent Testing Platform FAQ

What makes Agent to Agent Testing different from traditional QA?

Traditional QA is built for deterministic, rule-based software with predictable outputs. Agent to Agent Testing is designed for the dynamic, non-deterministic nature of AI. It uses other AI agents to simulate complex, multi-turn human conversations across various channels, testing for emergent behaviors, contextual understanding, and subtle failures like bias or tone-deviation that static tests cannot catch.

What types of AI agents can I test with this platform?

The platform is a unified solution designed to test a wide range of AI agents, including text-based chatbots, voice assistants, phone caller agents, and hybrid multimodal agents. It validates their behavior in simulated real-world environments for chat, voice, and phone interactions.

How does the platform ensure testing coverage for rare edge cases?

It employs a team of over 17 specialized AI agents dedicated to test generation. These agents are designed to think like adversarial testers, power users, and confused novices, autonomously creating diverse and unpredictable scenarios that probe for long-tail failures and complex interaction patterns far beyond a manual test plan's scope.

Can I integrate this testing into my existing CI/CD pipeline?

Yes, the platform seamlessly integrates with TestMu AI's HyperExecute for large-scale cloud execution. You can automatically generate test scenarios and run them at scale within your CI/CD workflow, receiving actionable feedback and risk reports in minutes to ensure quality with every code and model update.

PoYo API FAQ

How does the credit-based pricing work?

PoYo uses a flexible credit system where you purchase credits upfront. Each AI model has a cost per task denominated in credits (e.g., an image generation might cost 5 credits). You buy a pack of credits, use them for any model on the platform, and only pay for the tasks you successfully complete. There are no monthly subscriptions, and your purchased credits never expire, giving you complete control over your spending and usage.

Is there a way to test the models before integrating?

Absolutely. PoYo provides completely free playground access on each model's page. You can experiment with different models, fine-tune generation parameters like dimensions and style, and see live results without spending a single credit or providing a credit card. This allows you to debug, validate API behavior, and choose the perfect model for your needs before writing any integration code.

What happens if a generation task fails?

PoYo is built for developer peace of mind. If a task fails due to a platform or model error, you are not charged any credits. The system provides clear error codes and descriptions. Furthermore, you have full manual retry capabilities directly from your dashboard, giving you complete control over your workflow and ensuring you only pay for successful, high-quality outputs.

How do I receive the results from long-running tasks like video generation?

For tasks that take longer to process, such as video generation, PoYo utilizes an efficient asynchronous API. You have two robust options: you can poll the results using a simple query endpoint, or you can set up a webhook URL during task submission. The platform will then send an instant, real-time callback notification to your server the moment processing is complete, streamlining your application's workflow.
