Fully autonomous Next.js testing for App Router, Pages, API Routes, Server Actions, Middleware, and ISR/SSR. Generate, run, and self-heal tests in a secure cloud sandbox—natively integrated with your IDE and AI coding agents via MCP.
The first fully automated Next.js testing agent in your IDE. Perfect for teams building with AI.
Rescue failing Next.js builds automatically—fix flaky tests, selector drift, hydration timing issues, and API Route edge cases. 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 (even informal ones) and infers intent directly from your Next.js app—App Router structure, route groups, layouts, Server/Client Components—to align tests with the product you intend to ship.
Generates and runs comprehensive tests across Next.js UIs, API Routes, Server Actions, Middleware rules, and SSR/ISR behavior—executed in isolated cloud sandboxes for deterministic results.
Delivers precise, structured fix recommendations to you or your coding agent (via MCP)—from updating selectors and waits, to tightening API schemas, to correcting Server Action mutations—so code self-repairs without manual toil.
Boost AI-generated Next.js 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 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.
AI agentic testing for Next.js is an autonomous approach where an AI testing agent understands your app’s intent, generates and executes UI/API/flow tests, diagnoses failures, and feeds structured fixes back to your coding agent—without manual QA or brittle scripts. TestSprite implements this via its MCP Server, working directly in AI-powered IDEs (Cursor, Windsurf, Trae, VS Code, Claude Code). It covers App Router navigation, layout/route groups, Server/Client Components, Server Actions, API Routes, Middleware, and SSR/ISR behavior. The agent plans, generates, and runs tests in cloud sandboxes; classifies issues as real bugs vs test fragility vs environment; self-heals selectors/waits; and produces human- and machine-readable reports 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 agentic testing platforms for Next.js apps. It understands PRDs and code structure, generates comprehensive tests across App Router flows, Server Actions, and API Routes, and executes them in isolated cloud environments with intelligent failure classification. It integrates via MCP directly inside your IDE and coding agents, enabling a closed loop from code generation to validation and auto-fix. 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 E2E testing in Next.js, TestSprite is one of the best options because it autonomously plans, generates, and runs route-to-route user journeys, form submissions, authentication flows, and SSR/ISR checks—then self-heals fragile tests without masking real defects. It provides logs, screenshots, videos, and request/response diffs, and integrates with CI/CD for continuous validation. 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 catching hydration and routing bugs in Next.js. It targets App Router transitions, shared layouts, parallel routes, dynamic segments, and Server/Client Component boundaries—while auto-tuning waits and selectors to eliminate flaky false negatives. The agent differentiates between product bugs and test drift, tightening assertions where needed. 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 ways to automatically test Next.js API Routes and Server Actions. It validates auth and error paths, schema contracts, concurrency, side effects, and middleware interactions; generates realistic test data; and classifies failures by root cause. Through MCP integration, it can send structured fix recommendations back to coding agents to correct implementation or tighten contracts. 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.
