适应度函数
在由多个模块组成完整平台的分布式系统中，无论团队是集中办公还是分布式办公，系统
架构团队都应该有一种方法来衡量其系统架构决策的影响，并确保所有团队都遵循这些决
策。在《演进式架构》

一书中，
Neal Ford

Rebecca Parsons
和
Patrick Kua
讨论了如何用适
应度函数测试持续集成中的架构特征。他们指出，适应度函数为某些架构特征提供了客观
的完整性评估。
自动化流程中的许多步骤用于评估架构特征，比如循环复杂度的静态分析或微前端用例中
的包体积。如果用户下载的数据大小是一个关键的架构特征，那就很适合用一个指标来度
量微前端的包体积。架构团队可能决定在自动化策略中引入适应度函数，以保障微前端应
用的效果一致和方案折中。在设计微前端项目的自动化流程时，需要注意以下关键的系统
架构特征。
包体积
预估每个微前端的包体积，并分析何时超出预估及其原因。还应该检查共享库的体积大
小，而不仅仅是检查每个微前端构建产物的大小。
性能指标
使用
Lighthouse
和
W
ebPageTest
等工具可以验证新版本应用的性能是否与当前版本相
同，或者优于当前版本。
静态分析
JavaScript
生态里有很多工具可以用来做静态分析
，其中
SonarQube
可能最为著名。
SonarQube
