How do you verify front-end code in agentic LLM coding loops?
Large Language Modelsfront-endtestingagentic development
Agentic coding loops work well when the LLM can run tests to verify its work. For backend code, this is straightforward - write a test, run it, iterate. For front-end work, I haven't found a good workflow. I've tried Playwright MCP and Google Antigravity which has a Chrome integration with mixed results. How are you closing the loop on front-end verification?

Based on 2 community responses
Verifying front-end code in agentic LLM coding loops can be challenging due to the dynamic nature of front-end development. One approach is to leverage end-to-end testing frameworks like Playwright or Cypress, which can simulate user interactions and verify the correctness of the UI. Another strategy is to use visual testing tools like Percy or Applitools, which can capture and compare screenshots to detect visual regressions. Additionally, you can also explore using headless browsers like Puppeteer to automate testing and verification.
