Stop AI from hallucinating E2E test selectors — code analysis + live browser exploration via Claude Agent SDK and 2 MCP servers

📰 Dev.to AI

Prevent AI hallucination in E2E test selectors by using Claude Agent SDK and MCP servers for code analysis and live browser exploration

advanced Published 29 Apr 2026

Action Steps

Configure Claude Agent SDK to analyze code and generate E2E tests
Run live browser exploration using 2 MCP servers to validate test selectors
Apply code analysis results to refine test selectors and prevent hallucination
Test and validate the generated E2E tests using Playwright
Compare the results with and without Claude Agent SDK to measure improvement

Who Needs to Know This

QA engineers and developers can benefit from this approach to improve the accuracy of E2E tests generated by LLMs, reducing false positives and test failures

Key Insight

💡 AI-generated E2E tests can be improved by combining code analysis and live browser exploration to prevent hallucination of test selectors
