Post-Mortem: Surviving AI-Generated Playwright Tests in Production
Originally published on tamiz.pro . The promise of AI-assisted testing was speed. The reality, after six months of deploying AI-generated Playwright tests into a high-traffic production environment, is a nuanced landscape of high velocity and significant maintenance friction. While Large Language Models (LLMs) can generate a Playwright test script in seconds, the resulting code often lacks the…
The post-mortem analysis of deploying AI-generated Playwright tests in a high-traffic production environment reveals a complex landscape of both advantages and limitations. While Large Language Models (LLMs) can generate test scripts swiftly, the resulting code often lacks essential elements for reliable Continuous Integration (CI) and continuous deployment pipelines.
One notable finding is that AI excels at creating structural scaffolding but consistently struggles with state management, mitigating flakiness, and handling complex user flows without human intervention. The survival rate of these generated tests—defined as tests remaining stable and passing without manual refactoring—was initially low but improved significantly after implementing strict prompt engineering guardrails and post-generation linting.
