playwright-docs

從官方文件中提煉出的 Playwright Test for JavaScript 與 TypeScript 的陷阱、意外預設與建議模式。

playwright-docs 是什麼?

這個技能旨在成為 Playwright Test 的權威指南,特別是針對 JavaScript 和 TypeScript 開發者。它從官方文檔中精煉出最容易被忽略或誤解的細節,例如自動等待規則、定位器的嚴格模式、非直覺的超時行為、模擬的盲點、快照更新模式、CI 配置以及已被移除的 API。技能的核心價值在於提供清晰、可追溯的指引,每個建議都附有官方文檔的連結,方便開發者驗證。支援的平台包括 Playwright Test 1.64.1 for Node.js 和 TypeScript,並明確排除了 Python、Java 和 .NET 的內容。使用方式非常結構化:先閱讀快速入門了解核心規則,再根據具體任務(如定位器、斷言、快照、網絡、CI 等)參考對應的詳細文件。此外,它還包含一個「舊模式」對照表,幫助開發者從 Puppeteer、Protractor、Testing Library 或舊版 Playwright 遷移。此技能尤其適合在編寫、審查、除錯或配置 Playwright 測試時使用,特別是在處理不穩定的測試、定位器問題、網絡模擬、認證、分片測試或元件測試等複雜場景。

說明文件

Playwright 測試 (JS/TS) 官方文檔精華

概述

此技能匯集了 Playwright 文檔中容易出錯的內容:自動等待規則、嚴格模式、非預期堆疊的超時、模擬盲點、快照更新模式、CI 設定以及已移除的 API。它排除了通用測試建議。每一項聲明都附有來源文檔的 URL,以便查驗。

涵蓋版本

適用於 Node.js 與 TypeScript 的 Playwright Test 1.64.1 (@playwright/test)。不包含 Python、Java 與 .NET 的內容。如果安裝的版本較舊,請在應用較新的 API 前,先查閱 references/version-changes.md 中的版本對照表。

導覽方式

  1. 閱讀下方的快速入門。它涵蓋了大多數測試中重要的規則。
  2. 根據任務的領域,從文末的表格中開啟對應的參考文件。
  3. 在審查舊程式碼或升級之前,請閱讀下方的「舊模式」一節以及 references/version-changes.md。
