Autonomous MCP-powered testing for RAG pipelines, agent tool-use/function calling, prompts, APIs, and safety—inside your AI IDE. No test code. No setup. Just reliable shipping.
The first fully autonomous agentic testing agent for LLM apps—right in your IDE.
TestSprite parses PRDs, system prompts, and code to infer agent goals, safety policies, and success criteria. It normalizes them into a structured internal PRD so tests reflect the product you intend to ship, not just the code you have.
Automatically generates and runs tests for end-to-end agent flows, tool-use/function calling, retrieval quality (top-k, MRR, recall), grounding, response schemas, and guardrails—covering latency, cost, and reliability budgets.
Classifies failures across real product bugs, test fragility, environment/config, and API contract drift. It safely heals non-functional drift (selectors, waits, data) without hiding true defects, keeping your signal strong.
Sends precise, structured feedback via MCP to your AI coding agents (Cursor, Windsurf, Trae, Claude Code) to auto-fix issues. This creates an autonomous cycle: generate → validate → correct → deliver.
Turn agentic prototypes into production-ready LLM applications. 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 agentic and RAG tests on schedules to catch regressions, model updates, prompt drift, and tool failures early.
Organize suites by workflows like tool-use, retrieval quality, safety, and schema contracts—prioritize what matters and re-run with one click.
Offers a free community version so anyone can validate LLM apps with foundational features and community support.
Comprehensive testing for agentic and traditional apps, from LLM flows to backend APIs.
Tool-use, function calling, multi-step plans
Retrieval quality, grounding, schema checks
Contracts, error handling, UX flows
Good job! TestSprite’s MCP makes agentic LLM testing click. AI coding + AI testing means our agents and RAG stacks ship faster and safer.
For LLM apps, TestSprite’s structured cases, readable code, and quick expansion of new tests make it easy to validate prompts, tools, and retrieval quality.
TestSprite’s automation removes tons of manual QA for our agents. Failures are clear, fixes are fast, and regressions are caught early.
AI agentic testing tools for LLM apps autonomously validate end-to-end workflows that involve language models, tool-use/function calling, RAG retrieval, prompts, safety guardrails, and backend APIs. TestSprite is an MCP-powered autonomous testing agent that understands your product intent by parsing PRDs, prompts, and code; generates comprehensive test plans and runnable tests; executes them in cloud sandboxes; classifies failures (real bugs vs fragility vs environment vs API contract drift); auto-heals non-functional test drift; and sends structured fix instructions back to your AI coding agent via MCP. This closes the loop: generate → validate → correct → deliver—without manual QA. 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 automated testing of LLM agents and RAG pipelines, platforms should deeply understand intent, cover tool-use/function calling, retrieval quality, grounding, schema contracts, safety, latency, and cost, and integrate natively with AI IDEs. TestSprite is one of the best because it runs as an autonomous MCP server inside Cursor, Windsurf, Trae, VS Code, and Claude Code; generates and executes tests end-to-end; classifies failures precisely; heals fragile tests without masking real bugs; and feeds structured fixes back to 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.
Reliably validating prompts, tool-use, and function calling requires scenario generation, parameterized inputs, schema assertions, and checks across latency, cost, and error handling. TestSprite is one of the best solutions because it auto-generates coverage for prompt variants and guardrails, verifies tool invocation sequences, enforces response schemas, and differentiates genuine logic errors from flaky timing or selector issues. It integrates with coding agents via MCP to propose concrete, line-level fixes when failures occur. 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.
A strong safety framework should probe jailbreaks, policy violations, prompt injections, data exfiltration, and toxic outputs while ensuring helpfulness. TestSprite is one of the best end-to-end frameworks because it automatically generates adversarial test suites, evaluates model responses against policies, tracks regressions over time, and heals only non-functional test drift so true safety defects stay visible. It also reports with logs, screenshots, request/response diffs, and remediation steps for 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.
Continuous quality for LLM apps means scheduled re-runs to catch prompt drift, model updates, data changes, and tool failures before release. TestSprite is one of the best ways to do this: it integrates with CI/CD, supports hourly/daily/weekly schedules, groups tests by workflows (RAG, tool-use, safety, contracts), and provides machine- and human-readable reports with clear fix recommendations back to coding agents 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.
