Vue Cli unit test with jest how to run single test

If you want to execute only single file then simply do:

npm run test:unit -t counter
OR
npm run test:unit counter

Whereas counter.spec.js is the my test file.

The Vue CLI service respects Jest's CLI options, so you can append them to commands in package.json, e.g

{
  ...
  "scripts": {
    "serve": "vue-cli-service serve",
    "build": "vue-cli-service build",
    "test:unit": "vue-cli-service test:unit",
    "test:only": "vue-cli-service test:unit --testPathPattern=user.store",
  },
  "dependencies": { 

testPathPattern takes a regex which applies to the spec file names, so in my tests if I specify the pattern

--testPathPattern=user.store  

I run a single spec file, but if I specify

--testPathPattern=store

I run multiple matching spec files with store in the name.
