如何仅从特定文件夹运行 Jest 测试而忽略其他文件夹测试？

Question

I have a node js project and it have 2 test folders. There are app & admin folder inside of src/ test /v1. I want script to run test from only app folder. I tried using jest app , jest app --testPathPattern=src/__test__/v1/app" but both didn't worked.

By default jest will try to run all tests recursively of the root directory (where package.json is)

To specify a specific folder via CLI:

jest --testPathPattern=src/test/v1/app

You can also setup package.json to have specific test commands for running tests for specific folders:

"scripts": {
   "test:app": "jest --testPathPattern=src/test/v1/app",
   "test:admin": "jest --testPathPattern=src/test/v1/admin",
},
