Characteristic branches assist builders in agile groups be extra versatile with the event course of. It permits them to work on a brand new characteristic or repair an current challenge unbiased of the principle code line.
Most model management techniques immediately enable software program groups to make the most of branches. The naming system of every department depends upon the model management system you utilize.
A characteristic department permits steady deployment of bug fixes and new options with none interruption to the first code base.
On this article, we go over how an agile workforce makes use of characteristic branching methods for environment friendly software program growth.
Let’s get began.
Utilizing Characteristic Branching for Agile Growth
Branching permits builders to collaborate higher. Totally different branches don’t have an effect on one another’s progress. Even with short-lived branches, the code adjustments inside that department solely.

Since every growth workforce has its personal particular person branches, holding your codebase steady isn’t a difficulty. Alternatively, a number of builders engaged on the identical code create instability and launch delays.
In agile methodology, characteristic branches additionally embody characteristic flags. These are toggles that allow and disable options in a product.
This helps deploy code to the principle and develop department faster. It additionally helps activate the characteristic quick, making it a lot simpler to check and deploy it for the ultimate person.
Moreover, the builders and the branches created stay inactive for extended durations of time. No matter how lengthy it takes to develop the code, it by no means impacts the principle codebase.
If a check fails in a selected launch, the system admin reverts the characteristic flag. That enables the system to return to one of many earlier variations. In the meantime, the builders proceed to repair and arrange code higher.
Finest Practices of Characteristic Branching
Agile groups use the next greatest practices to make sure steady integration and success.
1. Give attention to Communication
Lack of communication is a significant challenge in growth. Nevertheless, the agile course of focuses on a tradition of communication and steady collaboration.
Moreover, creating a daily suggestions loop additionally helps guarantee all code goes by means of steady peer evaluation.
A extra sturdy peer evaluation course of means a extra environment friendly characteristic branching course of.
This minimizes merge conflicts, overlap points, and the probabilities of merging hell.
2. Maintain a Department Lifetime Restrict
A very good branching technique at all times has short-lived characteristic branches. A better variety of merge operations and speedy integration ensures lesser merge conflicts.
Whether or not you’re updating frameworks, tackling bug fixes, or including new options, your precedence must be a bug-less launch.
That mentioned, quite a lot of main releases nonetheless have bugs, extra so if you happen to merge early. There’s nothing improper with that if you happen to put characteristic flags in place so that you at all times have the choice to show the characteristic off.
Since every developer has their very own department to work on, it’s a good suggestion to restrict the whole variety of branches. This helps management and cut back the complexity of the code.
3. At all times Use Characteristic Flags
It’s necessary to reiterate the significance of characteristic flags as a part of the event lifecycle. An agile workforce at all times makes use of characteristic flags as a result of it helps them work quicker and with lesser threat.
With characteristic flags, each developer on the workforce merges their code with the supply code. The code nonetheless goes by means of a correct evaluation and testing. Nevertheless, there’s a better likelihood of it passing all checks, even when there are minor bugs current.
It’s as much as the backend workforce to unlock the characteristic each time it’s related. At instances, the end-user will get the choice to allow or disable a selected characteristic. A very good instance of this contains experimental options that you simply see in Android developer settings.
4. Identify Characteristic Branches with a System
It’s at all times greatest to have a correct naming conference if you’re creating a number of characteristic branches.
The first branches embody the grasp, growth, and high quality assurance branches. Nevertheless, it’s important to separate the supporting and short-term branches, together with the hotfix, experimental, and have branches.
Sticking to the suitable naming conventions permits groups to maintain observe of all of the branches.
Moreover, it helps preserve a extra environment friendly characteristic branching technique.
5. Scope Administration
Mission scope is essential to keep away from pointless useful resource wastage. At instances, a minor code change doesn’t require a separate characteristic department.
In case you create a characteristic department for each minor change, it results in greater prices, slower supply, and growth fatigue.
Be certain every characteristic department’s function is obvious and represents a significant change or addition to the code.
Different Branches in a Model Management Methods
Steady supply of long-lived characteristic branches additionally depends on various components. Earlier than we get into that, it’s important to find out about different department sorts.
- Grasp Department: The grasp or primary department is the present codebase in manufacturing that passes all of the workflow.
- Develop Department: That is the place all of the characteristic branches merge; at this level, automated checks begin operating and the code begins releasing by means of CI/CD pipelines.
- Hotfix Department: That is when a developer is making a direct change to the grasp department; hotfix branches are fast assist fixes that don’t have an effect on present growth.
- Launch Department: Launch branches are the ultimate stage the place characteristic branches find yourself. After verification, this department merges with the grasp department within the subsequent launch.
The grasp and develop branches are the first branches whereas the characteristic, hotfix, and launch branches are the supporting branches.
Advantages of Characteristic Branches
When using Git, builders write code on branches. The department is an extension of the principle code that’s editable with out inflicting adjustments to the bottom code.
When a number of builders and growth groups work with the identical code base, points crop up. Modifying, erasing, or including code with out overlap turns into troublesome, thus resulting in override of different builders’ adjustments.
On this case of 1 central code base, a characteristic department permits agile growth groups to create a brand new department from the grasp department. They then make any essential adjustments to that characteristic department with out affecting the principle code repository.
Every developer creates their very own characteristic department to repair the problem or check out the characteristic they want. Builders are likely to arrange a characteristic branching technique with automated testing if the majority of the duties contains bug fixes.
Nevertheless, each growth cycle requires code evaluations earlier than they transfer in the direction of merging. Merging is the method of incorporating a profitable characteristic department turn into the principle department.
Particular person branches add pull requests or merge requests after the evaluation. The characteristic department then merges with the principle department the place you final left the grasp department.
This method permits for a number of manufacturing environments and a number of adjustments whilst you reduce unknown dangers.
Characteristic Branching: Closing Ideas
Whereas agile characteristic branching is a wonderful method to make sure growth success, there are different methods too.
A launch branching technique works by making a growth department that merges into the principle department. Nevertheless, since many builders are engaged on the identical department, it’s tougher to handle.
There’s additionally process branching the place a venture breaks down into particular person duties. Job branches join points straight to the supply code. Since every challenge has a separate department and identify, it improves transparency.
No matter branching technique you utilize depends upon what sort of code and venture you’re working with.
