TDD (Test Driven Development) is getting more and more popular. But what can you do to take it to the next level? What if you could know if your tests are passing every time you save a file without taking your hands off the keyboard. This is what continuous testing gives you. In this session, we will cover how you can continuously test your PHP application. We will cover - Installation and configuration - Running the tests - Running static analysers - Executing tools that can make your life easier
