Playwright

Playwright end-to-end test rules from eslint-plugin-playwright, applied to TypeScript test files driven by the @playwright/test runner. Guard Playwright-specific patterns, locator usage, web-first assertions, focused/slowed tests. That would otherwise compile and run silently.

Source: eslint-plugin-playwright (MIT).

• playwright/expect-expect: Require every Playwright test body to contain at least one expect(...) call.
• playwright/max-expects: Limit the assertion count inside a single Playwright test body.
• playwright/no-conditional-expect: Reject expect(...) calls under if/try/catch or other conditional branches in Playwright tests.
• playwright/no-conditional-in-test: Reject conditional logic (if/switch/ternary) inside Playwright test bodies.
• playwright/no-duplicate-hooks: Reject duplicate Playwright setup/teardown hook calls (test.beforeEach/test.afterEach/etc.) in the same test.describe.
• playwright/no-duplicate-slow: Reject repeated test.slow() calls inside the same test, the first call already marks the test slow.
• playwright/no-element-handle: Reject the legacy ElementHandle-style Playwright API (page.$, page.$$).
• playwright/no-eval: Reject page.$eval and page.$$eval.
• playwright/no-focused-test: Reject test.only, test.describe.only, and similar focused Playwright tests.
• playwright/no-force-option: Reject Playwright { force: true } options on actionable commands (click, fill, …).
• playwright/no-get-by-title: Reject getByTitle(...) locators.
• playwright/no-hooks: Reject Playwright test.beforeEach/test.afterEach/etc. Hooks.
• playwright/no-nested-step: Reject nested test.step(...) calls.
• playwright/no-networkidle: Reject the networkidle load-state in page.waitForLoadState and navigation options.
• playwright/no-nth-methods: Reject .first(), .last(), and .nth(...) on locators.
• playwright/no-page-pause: Reject page.pause() debugging calls.
• playwright/no-skipped-test: Reject test.skip, test.describe.skip, and the conditional test.skip() annotation.
• playwright/no-slowed-test: Reject test.slow() marks on Playwright tests.
• playwright/no-standalone-expect: Reject expect(...) calls outside the body of a Playwright test or lifecycle hook.
• playwright/no-wait-for-navigation: Reject page.waitForNavigation.
• playwright/no-wait-for-selector: Reject page.waitForSelector.
• playwright/no-wait-for-timeout: Reject page.waitForTimeout(ms) sleeps.
• playwright/prefer-locator: Prefer locator-based Playwright APIs (page.locator(sel).click()) over page-level convenience methods (page.click(selector)).
• playwright/prefer-to-have-count: Prefer expect(locator).toHaveCount(n) over asserting on await locator.count().
• playwright/prefer-to-have-length: Prefer expect(value).toHaveLength(n) over asserting on value.length directly.
• playwright/prefer-web-first-assertions: Prefer Playwright web-first assertions (expect(locator).toBeVisible(), .toHaveText(...)) over composed manual waits.
• playwright/require-to-pass-timeout: Require an explicit timeout option on expect(...).toPass(...).
• playwright/require-to-throw-message: Require a message argument on expect(...).toThrow(...).
• playwright/valid-describe-callback: Validate the shape of Playwright test.describe callbacks.
• playwright/valid-expect: Validate expect(...) arity and matcher chaining: exactly one argument, terminated by a matcher call, and async matchers properly awaited.
• playwright/valid-title: Require non-empty static Playwright test and describe titles.
