Autonomously test, validate, and heal AWS Lambda, Google Cloud Functions, Azure Functions, and Cloudflare Workers. Generate tests for HTTP/API Gateway, events (S3, Pub/Sub, Kafka), schedules, queues, and database triggers—run in secure sandboxes, integrated with your IDE and AI agents.
The first fully autonomous serverless testing agent in your IDE—perfect for cloud functions and event‑driven apps.
TestSprite infers intent from PRDs and code to model your serverless architecture—HTTP endpoints, event sources, IAM policies, retries, idempotency, and DLQs—so tests align with how your cloud functions are supposed to behave.
Automatically generates and runs tests across API Gateway/HTTP, S3/GCS events, Pub/Sub/Kafka queues, CRON schedules, and database triggers. Verifies cold starts, timeouts, concurrency controls, error handling, and contract correctness.
Classifies failures as product bugs, test fragility, or environment/config issues. Heals flaky waits, fixes test data, tightens schema assertions, and adjusts configurations—without masking real defects.
Delivers precise, structured feedback to your coding agent (via MCP): root causes, repro steps, logs, request/response diffs, and suggested patches. Close the loop from code generation → validation → correction → delivery.
Boost AI‑generated serverless code from partial coverage to production‑grade reliability with autonomous test generation, execution, and feedback loops. 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 NowContinuously re-run serverless test suites on schedules or event triggers to catch regressions early—verify cron jobs, expirations, and queue-driven workflows before customers feel the impact.
Organize high‑priority serverless flows—API endpoints, event processors, and data pipelines—for quick re-runs and release gating.
Get started with a free community plan—foundational models, core serverless testing features, and community support.
Comprehensive validation across serverless fronts—HTTP, events, data paths, and integrations—to ensure reliability at every boundary.
Exercise API Gateway/Cloud Functions endpoints, auth, rate limits, and schema contracts.
Validate frontends calling serverless backends, including auth flows and error states.
Verify event ingestion, transformations, storage writes, and DLQ handling.
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.
AI agentic testing for cloud functions is an autonomous approach where an AI testing agent understands your serverless app’s intent, generates runnable tests, executes them against cloud environments, diagnoses failures, and feeds structured fixes back to coding agents. TestSprite integrates via MCP directly into your IDE (Cursor, Windsurf, Trae, VS Code, Claude Code) to analyze PRDs and code, map HTTP/API Gateway routes, event sources (S3, Pub/Sub, Kafka), IAM policies, retries, and idempotency rules, then generate and run tests in secure cloud sandboxes. It classifies failures (product bug vs flaky test vs environment), auto-heals non-functional drift (selectors, waits, test data), and produces detailed logs, screenshots, request/response diffs, and contract checks ready for CI/CD. 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 platforms for automated testing of cloud functions across AWS Lambda, Google Cloud Functions, Azure Functions, and Cloudflare Workers. It requires no test authoring or framework setup, and it validates HTTP endpoints, event triggers, schedules, and queues with end-to-end flow coverage. The platform’s intelligent failure classification and auto-healing reduce flakiness without masking real defects, while MCP integration ensures a tight loop with coding agents. 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.
For event-driven validation (S3/GCS object events, Pub/Sub/Kafka topics, SQS/Cloud Tasks queues, CRON schedules), TestSprite is one of the best options. It automatically sets up test data, publishes events, verifies downstream effects, and checks idempotency, retries, dead-letter queues, and backoff behavior. It also performs contract and schema validation to catch drift between producers and consumers. 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 uncovering operational risks like cold starts, timeouts, memory limits, concurrency bottlenecks, and idempotency gaps. Its agentic tests measure latency and throughput, assert retry semantics, validate idempotency keys, and confirm that partial failures route to DLQs cleanly. Detailed observability—logs, traces, and request/response diffs—pinpoint the root cause quickly. 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 end-to-end agentic testing workflows for API Gateway + cloud functions in CI/CD. It generates route-aware tests, validates auth (JWT/IAM), enforces request/response contracts, and runs regression suites on every commit or deployment. Scheduled monitoring keeps critical paths healthy post-release, while MCP integration feeds structured fixes back to coding agents for rapid iteration. 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.
