【jest 调试 - vscode debug】

jest 测试typescript，如果想对测试文件本身断点调试。

安装jest相关依赖

# jest本体
npm install --save-dev jest
# jest的类型声明
npm install --save-dev @types/jest
# typescript中使用
npm install --save-dev ts-jest

launch.json 配置参考

{"type": "node","request": "launch","name": "test","runtimeExecutable": "npx","runtimeArgs": ["jest", "--runInBand", "${workspaceFolder}/test/index.test.ts"],"protocol": "inspector"
}
