Using Jest, "no such file or directory" for .env.example

Using Jest, "no such file or directory" for .env.example

• .env.example file exists at <project-root>
• jest tests run fine normally with NODE_ENV=test jest

I've tried adding rootDir in config to <project-root>, did not solve the issue.

I'm excited to get this working as I'm evaluating it for use for my team.

Wallaby config:

module.exports = function () {
  return {
    files: ['src/**/*.js', '!src/**/__tests__/*.js'],

    tests: ['src/**/__tests__/*.js'],

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

    testFramework: 'jest',
  };
};

Jest config:

{
    "setupFiles": [
      "<rootDir>/webpack/jest/jest.js"
    ],
    "collectCoverageFrom": [
      "src/**/*.{js,jsx}"
    ],
    "testPathIgnorePatterns": [
      "<rootDir>[/\\\\](build|docs|node_modules|scripts)[/\\\\]"
    ],
    "testEnvironment": "node",
    "testURL": "http://localhost",
    "testResultsProcessor": "./node_modules/jest-junit",
    "transform": {
      "^.+\\.(js|jsx)$": "babel-jest",
      "\\.(gql|graphql)$": "jest-transform-graphql",
      "\\.(jpg|jpeg|png|gif|eot|otf|webp|svg|ttf|woff|woff2|mp4|webm|wav|mp3|m4a|aac|oga)$": "<rootDir>/webpack/jest/file-transform.js"
    },
    "transformIgnorePatterns": [
      "[/\\\\]node_modules[/\\\\].+\\.(js|jsx)$"
    ],
    "moduleNameMapper": {
      "^.+\\.css$": "identity-obj-proxy",
      "^react-native$": "react-native-web"
    }
  }

We use setupFiles, the error was thrown from code in there.
