httprunner3.x详细教程七(三种方式实现参数化数据驱动)

httprunner3.x支持三种格式的参数化数据,Parameters的入参说明如下:
- """ parse parameters and generate cartesian product.
- Args:
- parameters (Dict) parameters: parameter name and value mapping
- parameter value may be in three types:
- (1) data list, e.g. ["iOS/10.1", "iOS/10.2", "iOS/10.3"]
- (2) call built-in parameterize function, "${parameterize(account.csv)}"
- (3) call custom function in debugtalk.py, "${gen_app_version()}"
- Returns:
- list: cartesian product list
- Examples:
- >>> parameters = {
- "user_agent": ["iOS/10.1", "iOS/10.2", "iOS/10.3"],
- "username-password": "${parameterize(account.csv)}",
- "app_version": "${gen_app_version()}",
- }
- >>> parse_parameters(parameters)
- """
总结来说,支持三种入参,返回一个列表:
1、列表:["iOS/10.1", "iOS/10.2", "iOS/10.3"]
2、Parameterize类的回调,例如csv:${parameterize(account.csv)}
3、debugtalk.py的回调,${gen_app_version()}
在使用参数化之前,首先要导入pytest包,和httprunner的Parameters这个类

如果使用过pytest的参数化的小伙伴一定不会陌生,@pytest.mark.parametrize()会先将param作为一个动态参数,传递给param,然后由httprunner在进行参数化,httprunner在pytest的parametrize上封装了一层,增加了csv及debugtalk.py参数化的支持。
下面演示三种参数化如何设置:
第一种列表:
- #!/user/bin/env python

- if __name__ == "__main__":
- TestBaiduRequestTestCase().test_start()
结果:
- collecting ... collected 3 items
- demo_baidu_request_test.py::TestBaiduRequestTestCase::test_start[param0]
- demo_baidu_request_test.py::TestBaiduRequestTestCase::test_start[param1]
- demo_baidu_request_test.py::TestBaiduRequestTestCase::test_start[param2]
第二种debugtalk.py的回调函数:
在debugtalk.py中定义一个函数,返回列表:
- def get_username():
- return [
- {"username": "111111"},
- {"username": "222222"},
- {"username": "333333"},
- {"username": "444444"},
- {"username": "555555"},
- {"username": "666666"},
- ]
在demo_baidu_request_test.py文件调用:
- #!/user/bin/env python
- # -*- coding: utf-8 -*-

使用csv文件作为参数化输入时注意三点:
1,csv文件中的title要为变量名
2,csv映射的时候,参数名要以“-”分割,name和pwd使用的-进行分割
3,csv的路径要使用相对路径,不支持绝对路径不支持\\符号的路径
