Git version control and agile development practice: project experience sharing

Introduction:

In today's software development industry, version control and agile development have Become an indispensable tool and method. As the most popular distributed version control system at present, Git effectively solves the problem of multi-person collaborative development, while agile development emphasizes rapid response to changes, continuous delivery and team collaboration. This article will share my experience in applying Git version control and agile development in project practice.

1. The importance of version control

In the software development process, it often requires multiple people to collaborate on development, handle multiple branches, and trace back historical versions. Traditional version control systems such as CVS and SVN have many problems. Centralized management of code creates the risk of online conflicts and code loss. Git manages code through distributed management. Each developer can create his own branch locally for development and merge it with the trunk, which greatly reduces the probability of conflicts and the risk of code loss. Git also provides powerful branch management and historical backtracking functions to facilitate developers for version control and code management.

2. Application of Git in projects

1. Branch management:
   In agile development, we often encounter demand changes and parallel development, which requires reasonable Manage and switch branches easily. Git's branch management function is very powerful. We can create a new feature branch based on the trunk branch, develop and test on this branch, and then merge it with the trunk branch after completion. This can well ensure the independent work and collaborative development of team members.
2. Version management:
   Git can easily record every code change, save each version through the commit command, and can easily trace back historical versions. This is very helpful for version management in project development. It can quickly locate problems and restore erroneous operations, and also facilitates collaboration and communication between developers.
3. Conflict resolution:
   In multi-person collaborative development, it is easy for code conflicts to occur. Git provides conflict resolution tools and methods, which can easily merge conflicting code with your own code, resolve conflicts and retain their respective changes. Through Git's branch management and merging functions, code conflicts can be well solved and the coordination costs between developers can be reduced.

3. Practical experience in agile development

1. User stories:
   Agile development emphasizes the close cooperation between the team and users. User stories are an important tool in agile development. . During the project, we recorded user needs in the form of user stories, and then after multiple rounds of discussions and reviews, we split them into smaller story points and prioritized them. During each development iteration cycle, team members can plan and develop tasks based on user story points, and use Git for version control.
2. Continuous integration:
   Agile development focuses on continuous integration, quickly responding to changes and ensuring software quality through frequent integration of code, automated testing and deployment. After we submit the code to the Git repository, we use automated tools to build the code, unit test and integration test, and generate an executable version. Through Git and continuous integration, problems can be quickly discovered and solved, improving the quality and efficiency of software delivery.
3. Team collaboration:
   Agile development emphasizes collaboration and communication across the entire team, including code exchanges between developers and requirements discussions between team members and product leaders. Git provides a convenient collaboration tool for the team. Each developer can create his own branch for development, and conduct code review and merge through merge requests. Through Git's version control and team collaboration functions, the team's work efficiency and code quality can be improved.

Conclusion:

By applying Git version control and agile development methods in projects, we can better manage code, collaborate on development, and respond quickly to changes. Git provides powerful branch management and version control functions to help us deal with multi-person development, review historical versions, and resolve code conflicts. Agile development provides the values ​​and methods of rapid delivery, user needs priority and team collaboration. Through Git version control and agile development, we can develop software more efficiently and improve the quality and efficiency of project delivery.
