HttpRunner3.X开源接口测试框架学习(二)
debugtalk.py
每个项目应该并且只能有一个debugtalk.py文件。该文件具有多种功能。
作为项目的根路径锚,测试用例中的相对路径(例如引用测试用例或CSV文件)都基于此根路径
存储自定义python函数,在测试用例中调用的函数均在此文件中定义
HttpRunner框架中的变量
全局变量
全局变量在.env文件中定义,编写测试用例脚本时使用中${ENV(KEY)} 获取变量
pytest格式
用例级变量
在使用pytest格式编写测试用例时,variables用来定义变量,请注意如果全局环境变量与测试用例脚本中存在相同变量名,则优先使用用例级变量。即:测试用例变量>导出变量>测试套件配置变量>引用的测试用例配置变量
创建HttpRunner项目
httprunner框架提供了自动生成手脚架项目的功能,可以快速创建新项目。
#使用httprunner命令创建项目
httprunnerstartprojectdemo创建名为demo的httprunner项目
#自动生成的文件目录如下:
createdfolder:demo/har#har接口录制导出文件,用于生成测试脚本
createdfolder:demo/reports #测试报告存放目录
createdfolder:demo/testcases#测试用例存放目录
createdfile:demo/testcases/demo_testcase_request.yml#测试用例模板示例
createdfile:demo/testcases/demo_testcase_ref.yml#测试用例模板示例
createdfile:demo/debugtalk.py#debugtalk.py文件 #用于编写自定义函数
createdfile:demo/.env #全局环境变量定义文件
createdfile:demo/.gitignore
示例创建baidutest项目:

编写httprunner框架接口测试用例
httprunner提供了自动生成测试脚本的功能,利用har2case xxx.har命令可以将抓包工具导出的har文件转换为pytest格式测试用例(默认格式),也可以转换成yaml、json格式。
使用抓包工具录制业务:
如图使用charles工具录制导出har文件
har2case命令详解:
$har2case-h
usage:har2casehar2case[-h] [-2y] [-2j] [--filterFILTER]
[--excludeEXCLUDE]
[har_source_file]
positionalarguments:

pytestformatbydefault.

执行har2case doctest.har 命令后会在当前文件夹生成doctest_test.py测试用例文件
