This is to make sure same file gets covered by both unit/isolated tests and integration tests. * Add support for source maps. * Use code from dist always. * Use nyc to stop instrument. * Add integration test suite for production usage. * Use jest-cli. * Add support for running e2e tests. * Check gzipPath with fs.stat before serving Otherwise, serve package might throw issues other than ENOENT * Install chromedriver with npm install. * Install chrome on travis-ci. * Add --forceExit to Jest. * Run tests only on Node v6. That's because selenium-webdriver only supports Node 6 LTS. * Use chromedriver NPM module to install chromedriver. * Use wd as the webdriver client. * Run chromedriver before tests. * Run travis for both node 4 and 6 * Remove unwanted npm install script. * Move some common text utilities to next-test-utils * Add lint checks and testing in npm prepublish hook. * Use npm on travis-ci. We are having some caching issues with yarn and chromedriver. * Make tests work on windows.\n But chromedriver doesn't work. * Clean up dependencies. * Run chromedriver in background without any tools. * Fix a typo in the code. * Use ES6 features used in node4 inside the gulpfile. * Add some comments. * Add support for running in windows. * Stop chromedriver properly on windows. * Fix typos.
