How TCS built an agentic test orchestrator with Amazon Bedrock AgentCore

This article describes how TCS built an agentic test orchestrator using Amazon Bedrock AgentCore to automate software testing for BFSI clients, transforming requirements into executable tests with minimal manual effort.

• Specialized agents handle scenario design, Gherkin conversion, code generation, and test execution with project-specific context
• Multi-tenant architecture isolates each client's data, identity, and AWS KMS keys for financial services compliance
• Routes API tests to AWS Fargate and UI tests to Amazon ECS with EC2 for Selenium execution
• LangGraph workflow controls execution, failure classification, and safe automated corrections with bounded retries
• Achieved 88% effort reduction: from 200 hours to 24 hours for 100 test scenarios
• Integrates with Jira, BRDs, Swagger, GitLab, and captured UI flows as requirement inputs

The solution demonstrates how specialized agents, contextual retrieval, and isolated infrastructure enable AI-driven quality engineering at scale while preserving the governance and security controls required in regulated industries.
