react-native-google-analytics-bridge-mock

Mock for react-native-google-analytics-bridge, used for testing.

react-native-google-analytics-bridge is a great package to use Google Analytics from React Native apps.

We would like to mock react-native-google-analytics-bridge for developing and testing.

, but not to send tracking data at test. This package provides mocked classes "GoogleAnalytics" and "GoogleTagManager", that do nothing.

Installation

npm install --save react-native-google-analytics-bridge-mock

Usage

with mocha

Create a compiler that uses babel-register at the path you like. For example, create a file that contains below codes at test/lib/babel-register.js.

module.exports = require('babel-register')({
    plugins: ['react-native-google-analytics-bridge-mock/transform']
})

And then, you can test with:

mocha --compilers js:./test/lib/babel-register test

Or, you can use mocha.opts

 --compilers js:./test/lib/babel-register

with babel

You can mock at development phase. Create a .babelrc file in your project root.

{
  "presets": [
    "react-native"
  ],
  "env": {
    "development": {
      "plugins": [
        "react-native-google-analytics-bridge-mock/transform"
      ]
    }
  }
}

babel-presets-react-native is required when you use custom .babelrc at react-native.

You may need to reset bundle cache to enable settings. Run npm start -- --reset-cache.

How it works

react-native-google-analytics-bridge-mock/transform is a babel-plugin to transform the following code

import GoogleAnalytics from `react-native-google-analytics-bridge`

into

import GoogleAnalytics from `react-native-google-analytics-bridge-mock`

react-native-google-analytics-bridge-mock provides class definitions that has mocked methods provided by react-native-google-analytics-bridge.
