 * This script, paired with test-e2e-local.js, is the full suite of
 * tooling needed for a successful local testing experience.
 * This script is an helper to clean up the environment fully
 * before running the test suite.
 *
 * You should use this when switching between branches.
 *
 * It will:
 *  - clean up node modules
 *  - clean up the build folder (derived data, gradlew clean)
 *  - clean up the pods folder for RNTester (pod install) (and Podfile.lock too)
 *  - kill all packagers
 *  - remove RNTestProject folder
 *
 * an improvements to consider:
 *   - an option to uninstall the apps (RNTester, RNTestProject) from emulators
