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
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

Generating E2E tests with an LLM sounds great in a demo. You hand a Playwright test spec to Claude, ask it to produce TypeScript code, and the toy app passes. Plug it into a real codebase and the wheels come off immediately. The AI confidently generates await page.click('#login-button') for a project where the actual element is Sign in . Selectors are invented from common patterns ("most projects use #login-butto
