CICD详解

CICD定义

• Continuous Integration (CI) 持续集成
• Continuous Delivery (CD) 持续交付
• Continuous Deployment (CD) 持续部署

DevOps定义

DevOps（Development和Operations的组合词）是一组过程、方法与系统的统称，用于促进开发（应用程序/软件工程）、技术运营和质量保障（QA）部门之间的沟通、协作与整合。

DevOps的基础核心是CICD。

CICD的基础核心是自动化。

CI/CD is an essential part of DevOps methodology, which aims to foster collaboration between development and operations teams. Both CI/CD and DevOps focus on automating processes of code integration, thereby speeding up the processes by which an idea (like a new feature, a request for enhancement, or a bug fix) goes from development to deployment in a production environment where it can provide value to the user.

Continuous testing

In continuous testing, various types of tests are performed within the CI/CD pipeline. These can include:

• Unit testing, which checks that individual units of code work as expected

• Integration testing, which verifies how different modules or services within an application work together

• Regression testing, which is performed after a bug is fixed to ensure that specific bug won't occur again
