Jest preset

[egoist]

Basically this preset allows us to run jest with poi test --presets jest.

Anyone interested in this could look into the preset API, this preset might look like:

module.exports = options => {
  return poi => {
    poi.mode('test', () => {
      require('jest').run(['--config', JSON.stringify(jestConfig)])
    })
  }
}

Have to release this before v8.0.0

If you're working on a Vue project, test-vue-app will do the job for you, and the fact is that it works with other frameworks (most, like React, just add a .babelrc for React JSX) too.

@egoist If/when this preset exists and I am using vue, would you recommend sticking with test-vue-app or migrating to the poi preset?

[egoist]

@skiano test-vue-app would be easier cuz

1. you don't have to configure anything to use it
2. you don't need to use it with a specific build tool.

Maybe we can make test-vue-app become the poi in unit testing world 😄

@egoist that sounds great! I will just use that.

I love the idea of keeping the testing separate. If you want that to be like poi for testing , do you think it should be migrated to a different name? perhaps poi-test ?

[egoist]

@skiano that's for sure 😂

[egoist]

@skiano It's now renamed to tyu

@egoist thanks for the heads up!

@egoist would adding a babelrc file with the babel-preset-poi make jest work out of the box with poi?

[darcnite3000]

just to note that I recently tested adding the babel-preset and followed jest's babel 7 setup notes and it worked

.babelrc

{
  "presets": [
    "babel-preset-poi"
  ]
}

add jest

yarn add --dev jest babel-jest 'babel-core@^7.0.0-0' @babel/core regenerator-runtime

Yeah the official Jest doc has documented this: https://facebook.github.io/jest/docs/en/getting-started.html#using-babel
