    There are a lot of books and publications about the continuous integration in the world. But in my experience, it’s difficult to find information about how to open quality gates between automated tests and to continuous integration practice to in your current project. After reading several articles and even a couple of books, you will understand how to work with it. But what next? I will share with you practical tips and tricks on how to lift iron curtain to your automated tests before a continuous quality practice today.
