Issue description or question

I can't start wallabyjs on a create-react-app at all. Can you explain what I'm doing wrong

output when I start:

Wallaby.js configuration file

config directly pulled from https://wallabyjs.com/docs/integration/react-jsx.html

module.exports = function(wallaby) {
  // Babel, jest-cli and some other modules may be located under
  // react-scripts/node_modules, so need to let node.js know about it
  var path = require('path')
  process.env.NODE_PATH +=
    path.delimiter +
    path.join(__dirname, 'node_modules') +
    path.delimiter +
    path.join(__dirname, 'node_modules/react-scripts/node_modules')
  require('module').Module._initPaths()

  return {
    files: [
      'src/**/*.+(js|jsx|json|snap|css|less|sass|scss|jpg|jpeg|gif|png|svg)',
      '!src/**/*.test.js?(x)'
    ],

    tests: ['src/**/*.test.js?(x)'],

    env: {
      type: 'node',
      runner: 'node'
    },

    compilers: {
      '**/*.js?(x)': wallaby.compilers.babel({
        babel: require('babel-core'),
        presets: ['react-app']
      })
    },

    setup: wallaby => {
      const jestConfig = require('react-scripts/scripts/utils/createJestConfig')(
        p => require.resolve('react-scripts/' + p)
      )
      Object.keys(jestConfig.transform || {}).forEach(
        k => ~k.indexOf('^.+\\.(js|jsx') && void delete jestConfig.transform[k]
      )
      delete jestConfig.testEnvironment
      wallaby.testFramework.configure(jestConfig)
    },

    testFramework: 'jest'
  }
}

Code editor or IDE name and version

Hmm, it doesn't look like wallaby specific issue. Does npm test work for you?

[ArtemGovorov]

Just tried a freshly generated CRA (1.5.2) project on Windows 10 with the config above, and it is working for me.

I'm closing the issue because there's been no activity on it recently. If it is still a valid issue for you, please provide the info requested above.

@ThakurKarthik Does npm test work for you? If yes, please create a sample repo demonstrating the issue. we are happy to take a look.
