Continuous integration<\/p>\n

Traditional software development often lets developers work independently. Each is assigned a number of tasks where they work on their own computer and their works are not integrated until certain milestone. Developers work for weeks on tasks without realizing how many bugs that they created. Of course their tasks pass unit tests but problems often happen during integration test. The more their code is shared with others, the more problems they have and it takes lots of time and efforts to fix.<\/p>\n

Agile development avoids this problem by require all tasks to be integrated frequently, usually on a daily basis. This approach is called Continuous Integration (CI) and the rule is developers never leave anything un-integrated at the end of the day. When software is integrated daily, if there are problems they can be fixed immediately. By doing that, everyone will start each day with a clean build version of software and this increases the quality and productivity of the project. By allowing users to use software sooner, it encourages faster feedbacks between users and developers and helps the team do things right before the formal software release. Continuous integration works well when the team has automated unit tests that ensure software is constantly tested to reduce any risk that may happen at the end.<\/p>\n

With traditional development methods, integration does not happen until later and no one knows how many bugs that they have until integration test. It is risky as you are putting yourself into an unknown situation until the last minute. Sometime too many bugs could become a major schedule headache for the team. Continuous Integration solves this problem since you do not have to wait too long. If you make mistake you can fix it immediately. Of course Continuous Integrations does guarantee no bugs, but it makes them easier to find and fix. If you create any bug, you will find out quickly within few hours or at the end of the day so it is easier to fix since you just write the code and the logic is still fresh in your memory.<\/p>\n","protected":false},"excerpt":{"rendered":"
