This is Only Way to Debug AI Code That Works (Stop Wasting Time)

Описание: TestSprite MCP + Cursor Tutorial

Cursor 2.0 is wild. It built this full-stack fitness tracking app in minutes and I was convinced it was bug-free. Then I ran it through TestSprite MCP and it quietly uncovered issues I didn't even see coming.

Do you know you could be making a huge mistake by trusting AI-generated code for production? I've been making this mistake too.

When I pushed Cursor 2.0 to its limits by building this app from scratch, it ran perfectly — or so I thought. Cursor delivered a beautiful UI, the app architecture was right, and the logic was okay. But let me show you what I uncovered after running the code review using this AI testing MCP.

In this video, I walk you through building a complete fitness tracking app with Cursor 2.0, then testing it with TestSprite MCP to catch critical bugs before production — including authentication vulnerabilities, validation issues, and logic errors that could break your app.

Whether you're building with AI or just want to ensure production-ready code, this tutorial will show you the complete workflow from development to testing.

*TESTSPRITE MCP WORKFLOW DEMO*

Inside the video, you'll learn how to:

Build a Next.js app using Cursor's agent mode
Add visual enhancements with icons and styling
Run multiple Cursor agents for different tasks (mobile responsiveness, backend testing)
Sign up for TestSprite and create your account (free tier: 150 credits/month)
Install TestSprite MCP with one-click installation
Generate and configure API keys in TestSprite dashboard
Set up MCP server in Cursor settings
Prepare and upload PRD documents for testing
Configure frontend testing with login credentials and ports
Configure backend testing with API endpoints
Run comprehensive test suites that catch 8+ critical issues
Review detailed test reports with analysis, impact, and recommendations
Watch browser automation tests in action with screenshots
Access test recordings and previews in TestSprite dashboard
Debug and fix issues identified by TestSprite
Ensure code is production-ready before deployment

This is a complete, practical demonstration of how developers can combine Cursor 2.0's rapid development with TestSprite MCP's thorough testing to build production-quality applications.

CRITICAL ISSUES CAUGHT BY TESTSPRITE

TestSprite MCP uncovered serious bugs including:

Dashboard endpoint missing JWT authentication (allows unauthorized access)
Positive number validation problems
Weight calculation logic errors
Missing email format validation
Missing required attributes
Negative values accepted in workout forms
Submit button rendering issues
Edit workout response errors

Without TestSprite, these bugs would have made it to production.
