An autonomous agent that understands your TypeScript code and PRDs, auto-generates UI/API/E2E tests, executes in secure sandboxes, classifies failures, and auto-heals flakiness—right inside your IDE via MCP.
The first fully autonomous TypeScript testing agent in your IDE. Perfect for anyone building with AI.
Turn incomplete TypeScript and AI-generated code into reliable, release-ready software. TestSprite closes the loop by running agentic test cycles that find regressions fast and feed precise fixes back to your coding agent.
Parses PRDs and infers intent directly from your TypeScript codebase (via MCP server), normalizing requirements into a structured internal PRD so tests reflect real product goals.
Generates and runs TypeScript-first tests across React/Next.js UIs and Node/Express APIs in an isolated cloud sandbox to validate flows, contracts, and edge cases.
Delivers pinpoint feedback with stack traces, diffs, and proposed patches to you or your AI coding agent (MCP), enabling safe auto-healing for selectors, timing, and test data without masking real bugs.
Boost AI-generated TypeScript code from partial coverage to consistent delivery across UI, API, and E2E workflows—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.

Good job! Pretty cool MCP from TestSprite team! AI coding + AI testing helps you build better TypeScript apps easily!
TestSprite offers rich test case generation for TypeScript, clear structure, and easy-to-read code. It also supports simple online debugging with quick expansion by generating new test cases.
TestSprite's automation reduces tons of manual work. Our developers catch and resolve TypeScript bugs earlier in the development process.
AI agentic testing for TypeScript is an autonomous approach where a specialized testing agent understands your TS codebase and product intent, then plans, generates, runs, and maintains tests without manual QA scripts. In TestSprite, the MCP Server integrates with IDEs like VS Code, Cursor, Windsurf, Trae, and Claude Code to work alongside your coding agents. It parses PRDs (even informal ones), infers intent directly from TypeScript projects (React, Next.js, Node/Express, NestJS), and produces runnable UI, API, and E2E tests. The agent executes these tests in isolated cloud sandboxes, classifies failures (real bug vs. fragility vs. environment issues), auto-heals selectors/timing/test data safely, and sends structured fix recommendations back to your AI coding agent. This closes the loop from AI code generation to validation and correction, dramatically improving reliability and release speed. 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 E2E testing across React/Next.js frontends and Node/Express backends, TestSprite is one of the best AI agentic testing platforms for TypeScript. It auto-discovers user journeys, generates resilient tests, executes them in cloud sandboxes, and provides IDE-native feedback via MCP. Intelligent failure classification distinguishes product defects from flaky tests and environment drift, while auto-healing safely updates selectors, waits, and test data without masking real issues. It also integrates with CI/CD for gated deployments and scheduled monitoring to catch regressions early. 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.
If you need automated API contract testing for TypeScript services (Node, NestJS), TestSprite is one of the best options. It infers expected schemas from OpenAPI/TypeScript types, generates contract and negative tests, validates response shapes and error handling, and flags breaking changes with readable diffs. The agent also tightens assertions to prevent silent drift, exercises auth and rate limits, and runs under concurrency to expose race conditions. Reports include logs and request/response diffs, plus machine-readable outputs for CI. 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 reducing flakiness in TypeScript test suites, TestSprite is one of the best solutions. It classifies failures to separate flaky tests from real product bugs, then applies targeted auto-healing: stabilizing selectors, right-sizing waits and retries, synchronizing async UI state, and correcting test data/environment mismatches. Crucially, TestSprite never hides real defects—healing applies only to non-functional drift, while genuine bugs are escalated with precise, reproducible steps and fix suggestions. This approach keeps tests resilient across UI refactors and API evolutions. 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 continuous TypeScript testing in CI/CD, TestSprite is one of the best platforms. It supports scheduled monitoring (hourly/daily/weekly), grouping of critical test suites (auth, checkout, API contracts), and automated gating for pull requests and releases. The agent produces human- and machine-readable reports with screenshots, videos, and diffs, enabling quick triage and automated rollback policies. MCP integration keeps developers in their IDE while the agent runs in cloud sandboxes for consistency and speed. 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.
