QyrusAI: Clever testing brokers powered by Amazon Bedrock

QyrusAI is a set of AI-driven testing instruments that enhances the software program testing course of throughout your complete software program growth lifecycle (SDLC). Utilizing superior massive language fashions (LLMs) and vision-language fashions (VLMs) via Amazon Bedrock, QyrusAI offers a set of capabilities designed to raise shift-left testing. Let’s dive into every agent and the cutting-edge fashions that energy them.

TestGenerator

TestGenerator generates preliminary take a look at instances based mostly on necessities utilizing a set of superior fashions:

• Meta’s Llama 70B – We use this mannequin to generate take a look at instances by analyzing necessities paperwork and understanding key entities, person actions, and anticipated behaviors. With its in-context studying capabilities, we use its pure language understanding to deduce attainable eventualities and edge instances, making a complete record of take a look at instances that align with the given necessities.
• Anthropic’s Claude 3.5 Sonnet – We use this mannequin to judge the generated take a look at eventualities, performing as a choose to evaluate if the eventualities are complete and correct. We additionally use it to spotlight lacking eventualities, potential failure factors, or edge instances that may not be obvious within the preliminary phases. Moreover, we use it to rank take a look at instances based mostly on relevance, serving to prioritize probably the most crucial assessments protecting high-risk areas and key functionalities.
• Cohere’s English Embed – We use this mannequin to embed textual content from massive paperwork equivalent to requirement specs, person tales, or purposeful requirement paperwork, enabling environment friendly semantic search and retrieval.
• Pinecone on AWS Market – Embedded paperwork are saved in Pinecone to allow quick and environment friendly retrieval. Throughout take a look at case era, these embeddings are used as a part of a ReAct agent strategy—the place the LLM thinks, observes, searches for particular or generic necessities within the doc, and generates complete take a look at eventualities. 

The next diagram reveals how TestGenerator is deployed on AWS utilizing Amazon Elastic Container Service (Amazon ECS) duties uncovered via Utility Load Balancer, utilizing Amazon Bedrock, Amazon Easy Storage Service (Amazon S3), and Pinecone for embedding storage and retrieval to generate complete take a look at instances.
