Playwright Test(JS/TS)의 함정, 예상치 못한 기본 동작 및 권장 패턴을 공식 문서에서 추려냅니다. Playwright 테스트 작성, 리뷰, 디버깅 또는 구성 시 사용하세요.

playwright-docs란 무엇인가요?

이 스킬은 공식 Playwright 문서에서 실수하기 쉬운 핵심 내용을 정리한 지식 베이스입니다. 자동 대기 규칙, strict 모드, 예상과 다르게 동작하는 타임아웃, 모킹 시 놓치기 쉬운 부분, 스냅샷 업데이트 모드, CI 설정, 제거된 API 등이 포함되어 있습니다. 각 주장마다 출처가 되는 문서 URL이 함께 제공되어 언제든지 확인할 수 있습니다. Node.js 및 TypeScript 기반의 `@playwright/test` 1.64.1 버전을 기준으로 하며, Python, Java, .NET 내용은 제외됩니다. 이전 버전을 사용 중이라면 `references/version-changes.md`에서 변경 사항을 먼저 확인해야 합니다. 스킬은 크게 빠른 시작 가이드, 이전 패턴 표, 상세 참조 파일 세 가지로 구성되어 있습니다. 빠른 시작에서는 로케이터, 액션과 대기, 어서션, 설정 구조, 네트워크, CI, 스냅샷 등 가장 많이 사용되는 영역의 핵심 규칙을 다룹니다. 구체적인 작업 영역(로케이터 상세, 액션과 이벤트, 어서션, 스냅샷과 접근성, 설정, 타임아웃과 재시도, 픽스처와 인증, 네트워크와 모킹, API 테스트와 Clock, CI, 브라우저와 Docker, 디버깅과 리포팅, 컴포넌트 테스트와 마이그레이션, Codegen 및 에이전트 도구 등)은 tables에 연결된 13개의 참조 마크다운 파일로 분리되어 있어 필요할 때 열어볼 수 있습니다. 이 패턴을 통해 AI 에이전트는 전체 문서를 한 번에 읽지 않고도 현재 작업에 가장 관련 높은 정보를 빠르게 찾아 사용할 수 있습니다.

Playwright Test (JS/TS) - 공식 문서 기반

개요

이 스킬은 Playwright 문서에서 자주 실수하기 쉬운 내용들을 담고 있습니다: 자동 대기 규칙, strictness, 예상과 다르게 동작하는 타임아웃, 모킹의 사각지대, 스냅샷 업데이트 모드, CI 설정, 제거된 API 등. 일반적인 테스트 조언은 포함되지 않습니다. 모든 주장은 출처가 되는 문서 URL과 함께 제공되므로 확인할 수 있습니다.

적용 버전

Node.js 및 TypeScript 용 Playwright Test 1.64.1 (@playwright/test) 기준입니다. Python, Java, .NET 내용은 제외됩니다. 설치된 버전이 더 오래된 경우, 최신 API를 적용하기 전에 references/version-changes.md의 버전 표를 확인하세요.

탐색 방법

  1. 아래의 빠른 시작을 읽으세요. 대부분의 테스트에서 중요한 규칙들을 다룹니다.
  2. 작업 영역에 맞는 참조 파일 하나를 마지막 표에서 열어보세요.
  3. 기존 코드를 리뷰하거나 업그레이드하기 전에 아래 "이전 패턴"과 references/version-changes.md를 읽으세요.
