jest-runner-standard

Standard Style runner for Jest.

Motivation

I liked the idea of the jest-runner-eslint, and thought it would be great to have one like that for standard. I also wanted to add a nice error messaging that will give you some context about where in the code you made a mistake.

Show case

Not only we run them on file changes, alongside with related jest tests, but also we have this beautiful jest-like visualisation of the failure :-)

Usage

Make sure you have standard already installed.

npm install --save-dev jest-runner-standard

In your jest.config.js, assuming you want to run both your tests and linting:

module.exports = {
  projects: [
    {
      'runner': 'jest-runner-standard',
      'testMatch': ['<rootDir>/**/*.js'],
      'displayName': 'standard linting'
    },
    {
      'displayName': 'test'
    }
  ]
}

run

jest --watch

Profit!

Configuration

(Changed in 0.0.12) By default we don't fix standard errors. I would recommend using a IDE shortcut for that, or running a separate console command for that (standard --fix). Unfortunately having them done automatically on file-save tend to be a bit confusing to IDEs/Editors, for changing files you have your cursor in :-( But, if you want to try and see if the workflow suits you, run jest with STANDARD_AUTOFIX=true

Examples
