`npm run test` failed but `ng test` run successful-CodePudding

I don't know why ng test is run successful, and npm run test is failed

package.json

{
  "name": "fe-patient",
  "version": "0.0.1",
  "author": "Ionic Framework",
  "homepage": "https://ionicframework.com/",
  "scripts": {
    "commit": "git cz",
    "ng": "ng",
    "start": "ng serve",
    "build": "ng build",
    "test": "ng test",
    "lint": "ng lint",
    "e2e": "ng e2e"
  },
...

npm run test should do the same with ng test...

What i have tried and the issue still exists:

npm cache clean --force
rm -rf node_modules
rm -rf package-lock.json
npm install
npm run test

Angular 12 , npm 6.14.8, ionic 5

CodePudding user response：

Finally find the root cause...

Current we haven't written any UT (spec files), so we delete all the spec files.

ng test will show successful if there is 0 spec file,

npm run test will give an error if there is 0 spec file.

Update Better solution:

Update config in karma.conf.js will also work:

failOnEmptyTestSuite: false,
