An ESLint plugin that enforces best practices and catches common errors in Playwright test code.
ESLint Plugin Playwright is an ESLint plugin specifically designed for projects using the Playwright testing framework. It provides a curated set of linting rules that analyze Playwright test code to enforce best practices, prevent common errors like missing awaits or conditional expects, and promote the use of modern, reliable APIs. It solves the problem of maintaining high-quality, non-flaky test suites by catching issues early in the development cycle.
Developers and QA engineers writing and maintaining end-to-end test suites with Playwright, particularly teams looking to enforce consistent coding standards and prevent common pitfalls in their test code.
Developers choose this plugin because it offers targeted, framework-specific linting that generic ESLint rules cannot provide. Its unique value lies in its deep understanding of Playwright's API, allowing it to catch subtle errors and promote patterns that lead to more stable and efficient tests, directly improving test suite reliability.

Rules like `missing-playwright-await` automatically catch common asynchronous mistakes in Playwright API calls, preventing flaky tests before they run.
Rules such as `no-force-option` and `no-networkidle` actively discourage anti-patterns that lead to unreliable tests, as highlighted in the README's key features.
Rules like `consistent-spacing-between-blocks` and `prefer-hooks-on-top` enforce a uniform structure across test files, improving readability and maintenance.
Rules including `prefer-web-first-assertions` guide developers towards Playwright's recommended, more robust APIs, ensuring tests use up-to-date methods.
Setting up requires careful file targeting in ESLint configs (e.g., using the `files` field), which can be complex in projects with mixed test types or non-standard structures.
With over 40 rules, teams might face decision fatigue when customizing which rules to enable, potentially leading to configuration bloat and maintenance challenges.
As a community-driven project, it may have slower update cycles or less official support compared to plugins maintained directly by Playwright or larger organizations.
