Software testing 10 rules

本文提供了软件测试领域的十大最佳实践,包括早期频繁测试、整合应用开发与测试周期、制定全面测试计划等内容,旨在帮助团队提高软件质量并降低开发成本。

1. Test early and test often.

2. Integrate the application development and testing life cycles. You'll get better results and you won't have to mediate between two armed camps in your IT shop.

3. Formalize a testing methodology; you'll test everything the same way and you'll get uniform results.

4. Develop a comprehensive test plan; it forms the basis for the testing methodology.

5. Use both static and dynamic testing.

6. Define your expected results.

7. Understand the business reason behind the application. You'll write a better application and better testing scripts.

8. Use multiple levels and types of testing (regression, systems, integration, stress and load).

9. Review and inspect the work, it will lower costs.

10. Don't let your programmers check their own work; they'll miss their own errors.

内容概要:本文档是一份关于交换路由配置的学习笔记,系统地介绍了网络设备的远程管理、交换机与路由器的核心配置技术。内容涵盖Telnet、SSH、Console三种远程控制方式的配置方法;详细讲解了VLAN划分原理及Access、Trunk、Hybrid端口的工作机制,以及端口镜像、端口汇聚、端口隔离等交换技术;深入解析了STP、MSTP、RSTP生成树协议的作用与配置步骤;在路由部分,涵盖了IP地址配置、DHCP服务部署(接口池与全局池)、NAT转换(静态与动态)、静态路由、RIP与OSPF动态路由协议的配置,并介绍了策略路由和ACL访问控制列表的应用;最后简要说明了华为防火墙的安全区域划分与基本安全策略配置。; 适合人群:具备一定网络基础知识,从事网络工程、运维或相关技术岗位1-3年的技术人员,以及准备参加HCIA/CCNA等认证考试的学习者。; 使用场景及目标:①掌握企业网络中常见的交换与路由配置技能,提升实际操作能力;②理解VLAN、STP、OSPF、NAT、ACL等核心技术原理并能独立完成中小型网络搭建与调试;③通过命令示例熟悉华为设备CLI配置逻辑,为项目实施和故障排查提供参考。; 阅读建议:此笔记以实用配置为主,建议结合模拟器(如eNSP或Packet Tracer)动手实践每一条命令,对照拓扑理解数据流向,重点关注VLAN间通信、路由选择机制、安全策略控制等关键环节,并注意不同设备型号间的命令差异。
