XOA是什么
XOA（Xena Open-Source Automation）是一个开源的测试自动化框架，追求“高效、易用、灵活”的跨操作系统的开发框架。能与Xena现有解决方案无缝配合，借助XOA可调用Xena（Z系列打流仪、E系列损伤仪）完成自动化测试任务。同时它提供了操作接口可将其他仪表/设备做并栈集成测试验证，统一整理输出测试报告。
XOA包含：
XOA CLI、XOA Python API、XOA Python TestSuite、XOA Converter
XOA CLI
XOA CLI 提供了一套简洁直观的基于文本语言的独立命令，用以控制和集成 Xena测试仪硬件，实现各种测试任务的自动化。
任何客户端平台/编程语言（如 Python、Tcl、Bash）都可与 XOA CLI 配合使用。
CLI 可在远程登录终端上使用，直接向 Xena 测试仪发送命令。
ValkyrieManager通过测试端口配置文件（.xpc ），可在 XOA CLI 环境之间无缝转换。
XOA Python API
XOA Python API与XOA CLI和XenaManager无缝集成
- 面向对象的高级抽象： XOA Python API采用面向对象的方法，提供了更高层次的抽象，加快了自动化脚本的开发。
- 集成开发环境自动完成，内置手册： XOA Python API 包含 IDE 自动完成以及类、函数和 API 内置手册等功能，可显著提高开发效率。
- 命令分组和响应自动匹配：该功能允许命令分组和响应自动匹配，从而优化了测试执行效率。
- 服务器到客户端推送通知订阅： XOA Python API 支持服务器到客户端的推送通知订阅，降低了用户代码的复杂性。
- 支持 Python 3.8 及更高版本： XOA Python API 兼容 Python 3.8 及更高版本，确保与现代 Python 环境兼容。

XOA Python Test Suite/测试套件
XOA Python 测试套件是一个测试框架，为开发人员和测试专家执行和集成 Xena 测试套件提供了定义明确的 API。
该框架以自动化方式处理各种任务，如测试资源管理、测试执行和发布测试结果。
每个 RFC 测试套件都被设计成独立的 "插件"，可根据需要有选择性地集成到项目中。
目前，XOA Python 测试套件包括
- RFC2544
- RFC2889
- RFC3918
XOA Converter
如果您希望将当前的 Xena 测试套件配置快速迁移到 XOA，现在使用 XOA 转换器工具比以往任何时候都更容易。
以前，Xena的测试套件应用程序仅与Windows兼容。但今后，所有现有和未来的测试套件都将并入 XOA Python 测试套件，从而消除 Windows 限制。
为了简化过渡，我们推出了 XOA 转换器。该工具允许用户将现有的Xena测试套件配置（Xena2544、Xena2889和Xena3918）从Xena窗口桌面应用程序无缝迁移到XOA Python测试套件中。有了 XOA 转换器，迁移过程变得轻松简单。
Source Code
GitHub 是我们托管 XOA 源代码的首选平台，因为它具有出色的版本控制和协作能力。它为管理代码变更提供了一个极佳的环境，确保项目的历史记录完备且易于访问。我们崇尚开放，鼓励每个人使用、分享、贡献和反馈我们的源代码。GitHub 允许进行无缝协作，并促进以社区为导向的方法，让每个人都能积极参与 XOA 的开发和改进。我们重视来自社区的意见和贡献，因为这能提高源代码的整体质量和创新性。
