 ### Run E2E Tests
 
-After starting a dev server or a preview server, you can run e2e tests in another terminal:
-
-```bash
-# open Cypress GUI
-pnpm cy:open:dev
-pnpm cy:open:build
-# or, run tests in command line
-pnpm cy:run:dev
-pnpm cy:run:build
-```
-
-If you don't want to start a server and run tests in two different terminals, you can make use of the following commands:
-
 ```bash
 # run e2e tests in dev mode
 pnpm e2e:dev

 ### 运行 E2E 测试
 
-在启动开发服务器或预览服务器后，你可以在另一个终端中运行 e2e 测试：
-
-```bash
-# 启动 Cypress 图形界面
-pnpm cy:open:dev
-pnpm cy:open:build
-# 或者，直接在命令行中运行测试
-pnpm cy:run:dev
-pnpm cy:run:build
-```
-
-如果你不想在两个不同终端内启动服务器和运行测试，你可以使用如下命令：
-
 ```bash
 # 在开发模式下运行 e2e 测试
 pnpm e2e:dev
