BrowserContext
An abstraction layer unique to the Playwright framework, situated between a Browser instance and a Page. Each BrowserContext maintains its own isolated Cookie store, LocalStorage, and network rules, enabling complete state isolation between individual test cases.
Timeline (last 90 days)
Playwright's architecture is divided into three layers: Browser (browser process), BrowserContext (isolated environment), and Page (tab).
BrowserContext supports loading previously saved login states via the storageState parameter, bypassing the need to log in again for each test.
Playwright introduces a BrowserContext mechanism for context isolation, allowing states such as cookies, cache, and login status to be independent between different tests.
Playwright recommends that each test case exclusively uses one BrowserContext, which is destroyed after use to ensure state isolation between test cases.
2020年微软推出Playwright，支持多浏览器并引入BrowserContext概念实现轻量级隔离
EgoLite为每个Space创建BrowserContext时以COW（Copy-on-Write）方式引用主Profile的登录态数据，实现继承但隔离的效果
