Continuous integration is the practice of frequently updating a code repository to prevent conflicts between multiple developers. It maximizes productivity and ensures that every developer receives the most up-to-date copy of the programming code available. While it cannot alleviate all conflicts, it saves time and money.
Continuous integration (CI) is the practice of maintaining a repository of programming code updated frequently with a developer’s changes. This helps ensure that multiple developers don’t create conflicting programming code with each other. Without continuous integration, conflicts that prevent code execution become quite common.
In a multi-developer environment, it becomes necessary to form a system that allows developers to work together. A central code system is referred to as a code base or code repository and serves as the starting point for all developer work. Each developer in the group can have a different task. One might need to improve the user interface while another might need to fix a problem in the code.
Developers can work on different aspects of the program, but there is a chance that conflicts will arise. These conflicts can lead to program instability or even application failure. This forces developers to spend more time determining which particular part of the code is causing the problem. This results in lost productivity and time as developers are forced to fix problems that could have been avoided.
Continuous integration is the solution to this problem. Continuous integration ensures that every change a developer makes is immediately updated in the code repository. When another developer accesses your code repository, they will receive a copy of the previous developer’s changes. This helps ensure that every developer receives the most up-to-date copy of the programming code available.
Continuous integration does not prevent integration problems. While continuous integration helps limit integration problems, these problems still arise in all multi-developer environments. Even with continuous integration, it still takes time for each individual developer to make code changes. This results in some changes being made to the repository without other developers realizing it.
While continuous integration cannot alleviate all conflicts that arise in a multi-developer environment, it is an effective solution that maximizes productivity. It allows multiple developers to work together and build applications in a reasonable amount of time. Without it, developers would be forced to spend hours trying to fix problems that arise from trying to integrate two different pieces of code. This saves developers time and saves businesses and consumers money.
