React Native library testing with Travis CI

1. Create new RN project inside library folder

react-native init example

2. Copy scripts and example/scripts folders

3. Go to example folder and update package.json

  ...
  "scripts": {
    ...
    "preinstall": "node scripts/pre-install.js",
    "appium": "appium",
    "build:android": "scripts/build-android.sh",
    "build:ios": "scripts/build-ios.sh",
    "test:android": "appium-helper --platform android",
    "test:ios": "appium-helper --platform ios",
    "test": "jest",
    "test:local-e2e": "OS=both scripts/run-local-tests.sh",
    "run-emulator:android": "scripts/run-android-emulator.sh",
    "kill-emulator:android": "scripts/kill-android-emulator.sh"
    ...
  },
  "dependencies": {
    ...
    "your-rn-library": "file:../your-rn-library-latest.tgz"
  },
  "devDependencies": {
    "appium": "1.8.1",
    "babel-jest": "22.4.4",
    "babel-preset-env": "1.7.0",
    "babel-preset-react-native-stage-0": "1.0.1",
    "babel-preset-react-native": "4.0.0",
    "babel-preset-stage-0": "6.24.1",
    "jest": "22.4.4",
    "prop-types": "15.6.0",
    "react-test-renderer": "16.3.1",
    "tape-async": "2.1.1",
    "tipsi-appium-helper": "2.1.3",
    "webdriverio": "4.7.1"
  },
  "jest": {
    "preset": "react-native"
  }

4. Make testing app and add tests

5. In the root directory of your library, create a file named .travis.yml (see example)

• iOS build

- os: osx
  language: objective-c
  osx_image: xcode9.4

• Android build

  - os: linux
  language: android
  jdk: oraclejdk8
  sudo: required
  android:
    components:
      - platform-tools
      - tools
      - build-tools-26.0.3
      - android-21
      - android-26
      - sys-img-armeabi-v7a-android-21
      - extra-android-m2repository
      - extra-google-m2repository
      - extra-google-google_play_services

• If you need run test without RN

- language: node_js
  node_js:
    - "9"

6. Create .travis folder and copy files from this repo

7. Go to travis.org and add the repo that you want to use Travis with
