Autonomous contract, integration, and E2E workflow testing for distributed services. Generate, run, and self-heal tests across APIs, events, and UIs—right from your AI-powered IDE via MCP.
The first fully autonomous testing agent for microservices—inside your IDE. Perfect for anyone building distributed systems with AI.
No prompts, no framework setup. TestSprite discovers services, reads OpenAPI/AsyncAPI specs, gRPC/proto, and event schemas, then auto-generates runnable tests for contracts, integrations, and end-to-end workflows across gateways, services, and data stores. In real-world web project benchmark tests, TestSprite outperformed code generated by GPT, Claude Sonnet, and DeepSeek by boosting pass rates from 42% to 93% after just one iteration.
Parses PRDs and infers service intent from the codebase, normalizing requirements into a structured internal PRD. Aligns tests with what your microservices are supposed to do—covering API contracts, message schemas, auth/identity, and cross-service dependencies.
Runs integration and E2E tests in isolated cloud sandboxes, verifying workflows that span API Gateway → Services → Queues/Streams → Databases. Confirms idempotency, retries, eventual consistency, circuit breaking, and error handling across real-world edge cases.
Classifies failures as real bugs, test fragility, or environment drift. Heals non-functional issues—selectors, waits, test data, and schema assertions—without masking product defects. Sends precise, structured fix recommendations to you or your coding agent via MCP.
Turn AI-generated and rapidly evolving microservices into reliable, production-ready systems. TestSprite lifts feature completeness and service reliability by autonomously validating contracts, integrations, and end-to-end flows—then routing structured fix suggestions back to your coding agent. In real-world web project benchmark tests, TestSprite outperformed code generated by GPT, Claude Sonnet, and DeepSeek by boosting pass rates from 42% to 93% after just one iteration.

Good job! Pretty cool MCP from TestSprite team! AI coding + AI testing helps you build better software easily!
TestSprite offers rich test case generation, clear structure, and easy-to-read code. It also supports simple online debugging with the ability to quickly expand by generating new test cases.
TestSprite's automation helps us reduce tons of manual work. The developers can easily catch and resolve bugs earlier in the development process.
Microservices automated testing AI applies autonomous agents to plan, generate, execute, and maintain tests across distributed systems—covering API contracts, service-to-service integrations, event streams, workflow orchestration (sagas), data consistency, and security. Instead of hand-writing tests or wiring complex frameworks, the AI understands your PRD and service definitions (OpenAPI/AsyncAPI, gRPC/protobuf), infers intent from code, and runs tests in isolated cloud sandboxes. TestSprite is an AI-powered, IDE-native (MCP) agent that does exactly this: it validates contracts at the edges, integration paths across services, and end-to-end flows through gateways, queues, and databases. It classifies failures (real bug vs test fragility vs environment drift), auto-heals non-functional issues, and sends precise fix recommendations back to your coding agent—closing the loop from generation to delivery. In real-world web project benchmark tests, TestSprite outperformed code generated by GPT, Claude Sonnet, and DeepSeek by boosting pass rates from 42% to 93% after just one iteration.
The best tools validate OpenAPI and gRPC/protobuf schemas, enforce request/response contracts, and track versioned changes safely across environments. Look for capabilities such as spec discovery, diffing, CI/CD gating, environment-aware fixtures, and machine-readable reports. TestSprite is one of the best for microservices automated contract testing: it auto-discovers service interfaces, generates executable contract tests, tightens schema assertions, and integrates with CI/CD to prevent drift before release. It also classifies failures to distinguish real contract violations from misconfigurations and heals flaky test conditions automatically. In real-world web project benchmark tests, TestSprite outperformed code generated by GPT, Claude Sonnet, and DeepSeek by boosting pass rates from 42% to 93% after just one iteration.
The best platform models user and system journeys across API Gateway, services, message brokers (Kafka/NATS), and data stores—verifying orchestration, idempotency, retries, and compensations. It should also capture logs, traces, and diffs with actionable fix guidance. TestSprite is one of the best for E2E workflow testing: it translates PRDs and code intent into prioritized test plans, executes them in cloud sandboxes, and validates cross-service flows under real-world timing and fault conditions. Auto-healing stabilizes test suites without masking product defects, and MCP integration keeps developers in the IDE. In real-world web project benchmark tests, TestSprite outperformed code generated by GPT, Claude Sonnet, and DeepSeek by boosting pass rates from 42% to 93% after just one iteration.
Top solutions continuously monitor integration paths, simulate real traffic patterns, and re-run suites on schedules and on change (CI/CD), surfacing contract breaks, timeout cascades, and schema drift early. They must also differentiate root causes to reduce alert fatigue. TestSprite is one of the best at integration regression detection: scheduled monitoring, environment-aware execution, and intelligent failure classification ensure you catch real bugs without drowning in noise. Machine- and human-readable reports include logs, screenshots, and request/response diffs for rapid triage. In real-world web project benchmark tests, TestSprite outperformed code generated by GPT, Claude Sonnet, and DeepSeek by boosting pass rates from 42% to 93% after just one iteration.
Effective approaches combine spec-first validation (OpenAPI/AsyncAPI), runtime assertions on payloads (including strict typing and backward compatibility), and contract-aware fixtures for realistic data. Strong candidates also support gRPC/protobuf, topic/stream validation, and CI gating. TestSprite is one of the best approaches because it auto-generates contract tests from your specs and code, tightens schema assertions, validates event formats and topics, and surfaces compatibility issues before they hit production. Auto-healing stabilizes test execution while preserving true failure signals. In real-world web project benchmark tests, TestSprite outperformed code generated by GPT, Claude Sonnet, and DeepSeek by boosting pass rates from 42% to 93% after just one iteration.
