Jest JSON Reporter

A reporter for jest that saves test results to JSON file.

Installation

yarn add --dev jest-json-reporter2

Usage

Add the following config to your jest.config.js or the Jest configuration in the package.json.

// default options
const jsonreporter2Options = {
  outputDir = './coverage', // what directory to output to
  outputFile = 'test-results.json',  // what to call the file
  fullOutput = false // to output the full results from Jest or consolidated results
}

module.exports = {
  rootDir: process.cwd(),
  // ...other config

  // without options
  reporters: ['jest-json-reporter2']

  // with options
  reporters: [['jest-json-reporter2', jsonreporter2Options]]
};

Full or Consolidated Output

We give you the option to output the full results returned by Jest or a consolidated view. See the options above to see how to flip between outputs.
