Error: Could not find a config file based on provided values:
path: "E:\node\node-test\helloworld"
cwd: "E:\node\node-test\helloworld"
Config paths must be specified by either a direct path to a config
file, or a path to a directory. If directory is given, Jest will try to
traverse directory tree up, until it finds one of those files in exact order: "jest.config.js" or "jest.config.mjs" or "jest.config.cjs" or "jest.config.json".

解决方法 在项目目录下执行
npm init
然后就可以了
