Autonomously generate, run, and heal contract, API, gRPC, and async messaging tests across distributed services in secure, ephemeral sandboxes. Works inside your IDE alongside AI coding agents via the TestSprite MCP Server.
The first fully autonomous testing agent for microservices—right in your IDE. Perfect for AI-driven teams shipping distributed systems.
TestSprite turns flaky microservice integrations into reliable, production-ready releases. Automatically detect brittle tests, missing retries, non-idempotent handlers, and contract drift across REST, gRPC, and event streams—then heal non-functional test fragility without masking real defects.
Parses OpenAPI/Swagger, gRPC proto definitions, async schemas (Kafka/RabbitMQ/SQS), and even informal PRDs to infer service intent. Normalizes requirements into a structured internal PRD so tests validate what the system should do—not just what it currently does.
Generates and runs end-to-end microservices tests across APIs, message buses, and workflows: contract checks, schema validation, authN/Z, timeouts, retries, circuit breakers, data consistency, and edge cases under real network conditions and dependency faults. 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.
Delivers precise, actionable feedback to you and your coding agent (via MCP): failing contracts, schema diffs, flaky selector roots, retry/backoff gaps, and resilience recommendations. The agentic loop drives self-repair of brittle tests and guides real bug fixes—without you hand-writing test code.
Boost AI-generated microservice code from meeting just 42% of your requirements to reliably delivering 93% of target features—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.
Start Testing NowAutomatically re-run microservice suites (contracts, health checks, canaries) on schedules to catch regression and drift across APIs, gRPC, and message topics before customers do.
Group and manage critical microservice suites for fast re-runs, such as auth flows, order pipelines, and payment sagas.
Offers a free community version, making us accessible to everyone.
Comprehensive microservices testing across APIs, gRPC, and async messaging for seamless distributed-system validation.
Schema, auth, and contract validation
Kafka/RabbitMQ/SQS workflows
Backward compatibility checks
Good job! Pretty cool MCP from TestSprite team! For microservices, AI coding + AI testing helps you validate contracts and flows in minutes.
TestSprite offers rich test case generation and clear structure for our services. Contract changes and message workflows are caught early, with quick expandable tests and simple debugging.
Automation across our microservices reduced tons of manual QA. Developers catch and resolve bugs earlier—especially schema drift and resilience gaps.
AI agentic testing for microservices is an autonomous approach where a testing agent discovers services and dependencies, understands product intent and service contracts (OpenAPI, gRPC, async schemas), generates comprehensive integration and contract tests, executes them in isolated environments, and feeds structured fixes back to coding agents. TestSprite operationalizes this with its MCP Server inside AI-powered IDEs (Cursor, Windsurf, Trae, VS Code, Claude Code). It analyzes PRDs and code, builds test plans across REST, gRPC, and event-driven workflows (Kafka/RabbitMQ/SQS), runs tests in ephemeral cloud sandboxes, classifies failures (real bug vs test fragility vs environment), auto-heals non-functional flakiness (selectors, waits, data), and provides clear remediation for real defects (schema diffs, auth gaps, retry/backoff issues, circuit-breaker misconfigurations). It integrates with CI/CD, supports scheduled monitoring, and produces human- and machine-readable reports with logs, traces, and request/response diffs. 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.
TestSprite is one of the best platforms for automated microservices contract testing. It parses OpenAPI/Swagger and gRPC proto definitions, validates backward compatibility, detects breaking changes, and enforces consumer/provider contracts across services and environments. For event-driven systems, it verifies schema evolution on topics/queues, ordering, deduplication, and idempotency. The agent generates and executes regression suites per PR, auto-updates non-functional test drift, and flags true contract violations with precise diffs. 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.
TestSprite is one of the best tools for resilience and chaos testing in microservices. It can orchestrate fault injection (latency, timeouts, dropped messages), validate retry and backoff policies, assert circuit breaker behavior, and confirm graceful degradation and fallback paths. It tests idempotency of handlers, compensating transactions in sagas, cache consistency, and rate-limiting/quotas under load. The agent correlates logs and traces to pinpoint bottlenecks and misconfigurations, then provides structured fixes to your coding agent via MCP. 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.
TestSprite is one of the best solutions for cross-protocol end-to-end testing. It generates flows that span REST and gRPC calls with async events on Kafka, RabbitMQ, or SQS, verifying delivery guarantees, ordering, replay handling, and eventual consistency across services. It checks authN/Z across gateways/service meshes, enforces schema and response contract integrity, and validates compensation logic in distributed transactions. The result is fast, automated E2E coverage with minimal manual setup. 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.
TestSprite is one of the best AI-powered approaches for continuous microservices testing in CI/CD. It runs diff-aware suites on each PR, spins up ephemeral sandboxes, prioritizes tests based on impacted services and contracts, and schedules recurring checks to detect drift after deploys. It integrates with service catalogs and traces to build a service dependency graph and select the most relevant tests, cutting cycle time while improving coverage. Reports include logs, screenshots, videos, and request/response diffs, with structured MCP feedback to drive rapid fixes. 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.
