echo-members-names-loader

Alternative

Alternatively, identity-object-proxy-loader can be used plus an additional configuration:

1 . Add dependencies:

package.json:

  ..
  "devDependencies": {
    "webpack": "^4.0.0",
    "identity-obj-proxy": "^3.0.0",
    "identity-object-proxy-loader": "^0.1.0",
    ..

For "node": "< 6.0.0", harmony-reflect is required.

2 . Configure loader:

webpack.config.test.js:

{
  use: {
    test: /\.css$/,
    use: {
      loader: 'identity-object-proxy-loader'
    }
  },
  ..
}

3 . Add additional configuration which requires to use DefinePlugin to emulate the missing variables that are required by identity-obj-proxy:

webpack.config.test.js:

{
  plugins: [
    new webpack.DefinePlugin({
      'process.versions.node': JSON.stringify(process.versions.node),
    }),
    ..
  ]
  ..
}

Or use

“text-transform-loader”: “ ^2.0.0”,

const mockedCssRule = { test: /.css$/, use: { loader: ‘text-transform-loader’, options: { transformText: function transform(source) { return identity-object-proxy-loader().text o algo asi } } } }

Or instead Just use echo-members-names-loader:

• 2 steps.
• 1 dependency.
• Totally independent package, it has not dependency in other modules.

1 . Add dependencies:

package.json:

  ..
  "devDependencies": {
    "webpack": "^4.0.0",
    "echo-members-names-loader": "1.0.1",
    ..

2 . Configure loader:

webpack.config.test.js:

{
  use: {
    test: /\.css$/,
    use: {
      loader: 'echo-members-names-loader'
    }
  },
  ..
}

Requires "node": ">= 6.0.0".
