create react app : configure Jest : Run all test files

Question

I would like to configure npm test in my server. when I run npm test, it invokes react-scripts test which triggers a prompt window ( attached screen ). How do I avoid the prompt and run all testcases in the server.

"scripts": {
"start": "react-scripts start",
"build": "react-scripts build",
"test": "react-scripts test",
"lint": "./node_modules/.bin/eslint ."
},

Answer 1

To run all the tests, use "test": "react-scripts test --watchAll=false"

Answer 2

If you pass CI=true, it will run once without setting up that prompt as described at https://create-react-app.dev/docs/running-tests/#linux-macos-bash:

CI=true npm test

Answer 3

When you want to run all tests you can use npm test --watchAll

--watchAll looking for changes in the script and it's keep spinning. Is there any other argument that avoid prompt and run all testfiles ? – Vaporize

ReactScripts tests all uncommited files in git. What do you want to achieve? Run all of the tests even if something not has been changed? npm test as well goes into watch mode – Glynas

Answer 4

You can just update your package.json and in the scripts section update the test one with just "test": "jest"

It should run every test file that it can find in your project

It's not that simple, because CRA programatically sets config you may be relying on: https://mcmap.net/q/827277/-how-can-i-make-jest-run-with-the-same-config-as-react-script-test-on-a-create-react-app – Lichi
