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

HttpRunner3.X开源接口测试框架学习（二）

 

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
 httprunner startproject demo    创建名为demo的httprunner项目
#自动生成的文件目录如下：       
created folder: demo/har                    #har接口录制导出文件，用于生成测试脚本
created folder: demo/reports                #测试报告存放目录                   
created folder: demo/testcases              #测试用例存放目录
created file: demo/testcases/demo_testcase_request.yml   #测试用例模板示例
created file: demo/testcases/demo_testcase_ref.yml       #测试用例模板示例
created file: demo/debugtalk.py             #debugtalk.py文件  #用于编写自定义函数
created file: demo/.env                     #全局环境变量定义文件
created file: demo/.gitignore           
  

示例创建baidutest项目：

C:\github>httprunner startproject baidutest
2020-08-11 14:32:19.860 | INFO     | httprunner.scaffold:create_scaffold:43 - Create new project: baidutest

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

HttpRunner3.X开源接口测试框架学习（二）

har2case命令详解：

$ har2case -h
usage: har2case har2case [-h] [-2y] [-2j] [--filter FILTER]
                         [--exclude EXCLUDE]
                         [har_source_file]
​
positional arguments:
  har_source_file       Specify HAR source file
​
optional arguments:
  -h, --help            show this help message and exit
  -2y, --to-yml, --to-yaml
                        Convert to YAML format, if not specified, convert to
                        pytest format by default.
  -2j, --to-json        Convert to JSON format, if not specified, convert to
                        pytest format by default.
  --filter FILTER       Specify filter keyword, only url include filter string
                        will be converted.
  --exclude EXCLUDE     Specify exclude keyword, url that includes exclude
                        string will be ignored, multiple keywords can be
                        joined with '|'

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

执行httprunner测试用例

使用hrun doctest_test.py 或者 pytest doctest_test.py 均可执行测试用例。
