Python生成JMeter测试脚本----HTTP信息头管理器和用户定义的变量

前言

之前的文章写了怎么用python生成JMeter脚本，生成了测试计划、线程组、Http监听器组件、响应断言、查看结果树、汇总报告、聚合报告、响应时间图。本篇内容接着讲怎么用python生成HTTP信息头管理器和用户定义的变量组件。

HTTP信息头管理器

信息头管理器的内容比较简单，主要包括了名称，注释和请求头参数。使用set方法设置好参数后，用get方法生成组件。

import xml.etree.ElementTree as ET
from base import Generalclass JMeterHeaderManager:def __init__(self):self.__name = 'HTTP信息头管理器'self.__comments = ''self.__headers = {}def get_name(self):return self.__namedef set_name(self, name):self.__name = namedef get_comments(self):return self.__commentsdef set_comments(self, comments):self.__comments = commentsdef get_headers(self):return self.__headersdef set_headers(self, headers):self.__headers = headersdef get(self, parent):header_manager_prop = ET.SubElement(parent, 'HeaderManager')header_manager_prop.set('guiclass', 'HeaderPanel')header_manager_prop.set('testclass', 'HeaderManager')header_manager_prop.set('testname', self.__name)if self.__comments != '':comments_prop = General.add_str_prop(self, header_manager_prop, 'TestPlan.comments', self.__comments)collection_prop = ET.SubElement(header_manager_prop, 'collectionProp')collection_prop.set('name', 'HeaderManager.headers')if self.__headers:for key, value in self.__headers.items():element_prop = ET.SubElement(collection_prop, 'elementProp')element_prop.set('name', '')element_prop.set('elementType', 'Header')header_value_prop = General.add_str_prop(self, element_prop, 'Header.name', key)header_value_prop = General.add_str_prop(self, element_prop, 'Header.value', value)hashtree = ET.SubElement(parent, 'hashTree')return header_manager_prop

用户定义的变量

用户定义的变量格式和信息头管理器一致，使用方法也一致，对于变量的描述，因为没有实际的用途，所以就不去实现了。

import xml.etree.ElementTree as ET
from base import Generalclass JMeterArguments:def __init__(self):self.__name = '用户定义的变量'self.__comments = ''self.__arguments = {}def get_name(self):return self.__namedef set_name(self, name):self.__name = namedef get_comments(self):return self.__commentsdef set_comments(self, comments):self.__comments = commentsdef get_arguments(self):return self.__argumentsdef set_arguments(self, arguments):self.__arguments = argumentsdef get(self, parent):arguments_prop = ET.SubElement(parent, 'Arguments')arguments_prop.set('guiclass', 'ArgumentsPanel')arguments_prop.set('testclass', 'Arguments')arguments_prop.set('testname', self.__name)arguments_prop.set('enabled', 'true')if self.__comments != '':comments_prop = General.add_str_prop(self, arguments_prop, 'TestPlan.comments', self.__comments)collection_prop = ET.SubElement(arguments_prop, 'collectionProp')collection_prop.set('name', 'Arguments.arguments')if self.__arguments:for key, value in self.__arguments.items():element_prop = ET.SubElement(collection_prop, 'elementProp')element_prop.set('name', key)element_prop.set('elementType', 'Argument')arguments_value_prop = General.add_str_prop(self, element_prop, 'Argument.name', key)arguments_value_prop = General.add_str_prop(self, element_prop, 'Argument.value', value)arguments_value_prop = General.add_str_prop(self, element_prop, 'Argument.desc', '')arguments_value_prop = General.add_str_prop(self, element_prop, 'Argument.metadata', '=')hashtree = ET.SubElement(parent, 'hashTree')return arguments_prop
