End to end or acceptance tests are very important for every application. The code can work perfectly but user still can see blank screen on a site. How to avoid this? This training teaches how to drive browsers via Selenium WebDriver; how to test complex UIs, and deal with single page applications. We will also cover ATDD and BDD practices to write specification and tests before the actual code. As a primary tool for web testing we use Codeception which allows to write tests effectively in by implementing high-level API. Such tests are easy to write, read and maintain. We will also cover how to manage data inside a test.
