    CI systems allow detecting integration errors as quick as possible because each integration is verified by an automated build. Another good thing about it is that with the help of CI tools developers can find errors sooner than later. It is well know fact that when some part of a code is not properly tested, developers may face with blocking issues right at the demo version. So, if you want every part of your code work nice with other parts of your system, CI system can be a wonderful solution of your problem.



      What is CI?

      First of all, let’s try to understand what is Continuous Integration (CI). According to Wikipedia CI is the practice of merging all developers working copies to a shared mainline several times a day.

      This method was firstly proposed by Grady Booch in 1991, though he did not prove that developers need integrating several times a day.

      However, five years later Kent Beck created Extreme Programming ( XP), where he advocated integrating more than once per day, perhaps even more than ten times per day.

      Benefits of using Continuous integration tools

      Now let’s look at the benefits you can get using CI. There are many advantages of CI systems, but in this article we decided to emphasize only four of them.

      • Reduced integration risk

      This is not a secret, that large products require many developers working on different parts of the code. If you have beginners in your team, the process of integration can become very risky. Though, if you have integration on a daily basis, it helps you to reduce integration risk.

      • Reduced deploying time

      Another advantage of CI system is that it helps to reduce deploying time, and most experienced developers know that the process of deploying projects is usually very difficult and time-consuming.

      • Better results

      Do you remember your first days at work? When you were afraid to break the code and that is why you  prefered to do nothing? This is how beginners feel or people who have just come to the project and do not know much about it. But this fear to break something  block their ability to work and create something new.

      To put it another way, people need to feel confident in order to work, they should not be afraid to break something  and get fired. That’s why developers need CI systems in order to help people to integrate easier to the project and feel more comfortable doing their job right away.

      • Easier life for QA team

      We think that you already know that this is task of QA team to fix everything that is broken in the process of project deploying. So, CI systems help isolate and trace bugs efficiently and the earlier bug is found the better it is for QA engineers.
