[Vuejs]-Vue-jest Failed to collect coverage from vue file

This is self answer. Well it was silly problem.

There are three problem

1. preset: '@vue/cli-plugin-unit-jest/presets/no-babel' in jest.config.js make transform option useless

   • removed

2. Jest 24 dosen’t support babel 6.

   • it should be
     babel-jest": "^23.6.0"

3. transform’s location was wrong

   • it should be like

  transform: {
    "^.+\\.js$": "<rootDir>/node_modules/babel-jest",
    ".*\\.(vue)$": "<rootDir>/node_modules/vue-jest"
  }

Now i fixed three problem. and working good.

I leave this answer because I want my shameful behavior to help others.
