横向拆分和纵向拆分
项目采用横向拆分还是纵向拆分会明显影响开发体验。纵向拆分就是微前端表现为单一
HTML
页面
，或一个团队独立负责单页应用。在这种情况下，开发体验与传统的单页应用
的开发体验非常相似，所有单页应用的工具和工作流在这里都适用。你可能还想创建一些
额外的工具用于特定条件下的微前端测试。比如，当一个
App shell
加载纵向拆分的微前端
时，你可能需要一个脚本或工具来测试应用在特定环境下的可用性，以确保微前端可以在
最新版本或者特定版本中正常运行。
测试阶段与普通的单页应用非常相似，我们可以配置单元测试、集成测试和端到端测试，
不需要额外的处理。因此，每个团队可以测试自己的模块以及模块之间的切换。但是，我
们要确保当前业务内的所有模块在
App shell
中加载时都是可用的。我曾经看到的一个很好
的解决方案是让维护
App shell
的团队对各模块进行端到端测试，以便覆盖所有模块。
横向拆分有不同的考虑因素。一个团队可能负责多个微前端，它们被一个或多个页面使
用。需要提供一些工具用于测试这些页面，让开发人员能够查看总体情况、潜在的依赖冲
突以及与其他团队负责的业务通信等。这些工具没有统一标准，许多公司需要开发定制化
的工具。需要注意的是，选择怎样的工具取决于环境和具体业务，因此，一家公司的工具
可能并不适合另一家公司。虽然也有一些现成的工具可以使用，但更多时候还是需要定制
一些工具来提供良好的开发体验。
横向拆分的另一个挑战是如何运行可靠的测试方案。我们需要确认单个业务的端到端测试 ...
