示波器需要多少模拟通道？ 您在使用示波器时面临的最大挑战是什么？
随着软件开发在造车行业中占有越来越重要的地位，敏捷开发的思想在造车领域中也逐渐地被重视起来，随之而来的是整车厂对自动化测试需求越来越强烈。本文结合在自动化测试方面的丰富经验，简单介绍一下实施自动化测试可能需要具备的技能及具体实践流程。


自动化测试城门-Python



要实现完全的自动化测试，我们首先要做的是先实现半自动化测试，即编写自动化测试脚本。俗话说Life is short，I use Python，Python作为一种简单易上手的高级编程语言，凭借其“无所不包”的库，成为测试脚本开发的不二之选。这里简单介绍一下，测试脚本开发常用的一些Python标准库。


城门士卒-os库


在编写测试脚本时，不可避免地会遇到对文件路径的获取及编辑，os库里的path函数可以方便地实现这些操作，如绝对路径获取os.path.abspath()、路径拼接os.path.join()、路径存在判断os.path.exist()等；如果你需要在Python中运行测试工具提供的命令，那么os库的system函数或popen函数可以让你方便地调用cmd(Windows)或shell(Linux)。


城门士卒-sys库


如果你所编写的测试脚本有跨平台运行的需求，那么你可以通过sys库的platform函数获取脚本的运行环境。根据运行环境的不同，编写不同的批处理命令；sys库中的argv函数，还可以为你的测试脚本提供简单的命令行接口，当你的脚本需要接收外部传递的参数时，你可以通过sys.argv[]方便地获取。而如果你需要编写更复杂更友好的命令行接口，你需要使用Python的另外一个标准库argparse来实现。


城门队长-re库


正则表达式是编写测试脚本的必备技能，因为有时我们会遇到复杂的文本处理，如在工程文件中查找需要修改的配置，并将其修改为我们所需要的内容。此时一般的查找替换函数就很难实现这个功能，我们只能借助强大的re库（正则表达式）来解决这个棘手的问题。re库提供的函数有：

re.compile():编译正则表达式，生成一个 Pattern 对象;

re.findall():搜索所有满足条件的字符串;re.match():从第一个字符开始匹配模式;

re.search():搜索第一个满足条件的字符串，查找到第一个停止;

re.sub():替换满足条件的字符串。


在使用re模块时，我们一般先用re.compile()将正则表达式编译生成为一个Pattern对象，然后再基于这个对象进行findall、match等操作，这样既可以提高代码的可读性，也可以提高代码的运行效率。

使用正则表达式进行查找替换是很方便的，但是在很多时候我们需要在匹配的字符串前后添加内容，并且保留匹配的内容，这时普通的查找替换是难以实现的。

如：希望将hour: minute格式后添加:00，形成hour: minute: seconds这种格式。此时可以采用如下方式来实现：

查找的正则表达式：

(\d:\d)

替换为：

\1\:00


这里，我们在替换的字符中使用\1，来引用正则表达式中第一个分组匹配到的内容，如果正则表达式中有多个分组，可以依次使用\2\3等进行引用，可以使用\0来引用整个正则表达式的内容。


小结



在掌握了Python基础语法和这三个标准库后，自动化测试的大门就为我们敞开了。但是想要编写一个可以驱动测试工具进行测试的脚本，我们还需要了解测试工具在headless模式 下的接口情况，如果工具提供的接口丰富，可以实现在headless模式[1]下对测试工程进行配置和执行等操作，那么我们的测试脚本开发工作将会顺利地进行。

但是如果工具提供的headless模式接口有限，无法满足测试脚本的需求，那么进入自动化测试大门后，等待我们的就是另一个棘手的问题：如何对工程文件进行解析与修改。考虑到大部分的工程文件都是XML格式的，因此后续我们就简单介绍一下如何通过Python解析和修改XML文件。

[1]：这里的headless模式是指在不使用工具GUI的情况下，以纯命令行的方式进行工具使用的模式。


自动化测试瓮城——XML文件



瓮城守备—XML解析



在Python的标准库中，有专门处理XML文件的库，无需安装第三方库就可以使用Python进行XML文件的解析，但是要想准确地从XML文件中解析出想要的信息，我们首先需要简单了解一下XML的文件结构。如下是一个简单的XML文档。

其中Harry Potter元素的结构如下图所示

在该XML文本中，根元素是，文档中的所有元素都被包含在里。元素有 4 个子元素：、< author>、<year>、<price>。每个子元素都包含一个文本内容，但只有子元素title和元素book拥有属性。</span></section><section style="white-space: normal;line-height: 2em;margin-left:

、双引号"、单引号'。如果使用Python的xml.dom.minidom库解析并使用writexml输出XML文件，该库会将这些实体引用转义为其实际字符进行保存。如果不对XML对象中的内容进行处理，导出的XML文件将会存在很多错误。</span></section><section style="white-space: normal;line-height: 2em;margin-left:

Job，Jenkins将Pipeline作为优先开发项目。这就意味着Pipeline在应用程序中是作为实体被设计和支持的，而不是通过在Jenkins中连接一堆任务而形成流水线。Pipeline类型的Job可以通过编程实现，可以实现更复杂构建逻辑和工作流，更重要的是在Pipeline中有专门的用于流水线编程的结构化DSL，其可以在工作空间中轻松地实现文件共享功能。同时Pipeline具有全新的Jenkins可视化界面
