Httprunner3.x参数化示例

框架作者没有对pytest格式的测试用例做一个参数化的官方demo,这里补充一下.

如果要对断言做关联参数化,框架本身是不支持的,需要改源码:这里-优化断言正则匹配
部分

只参数化请求报文内容的话,则不需要修改源码.

使用环境变量.env-作用域: 整个项目

import sys
from pathlib import Path
import pytest
sys.path.insert(0, str(Path(__file__).parent.parent))


from httprunner import HttpRunner, Config, Step, RunRequest, RunTestCase
from httprunner import Parameters


class TestCaseBattle(HttpRunner):

    config = (
        Config("battle: login")
        .base_url("http://xxx.xx.xx.225:12356")
        .verify(False)
    )

    teststeps = [

        Step(
            RunRequest("post form data")
            .with_variables(**{"res":"please select One Equipment"})
            .post("/login")
            .with_data({"username":"${ENV(username)}","password":"${ENV(password)}"}) #调用env变量
            .validate()
            .assert_equal("status_code", 200)
            .assert_regex_match("body", "${res}")
        ),
    ]


if __name__ == "__main__":
    TestCaseBattle().test_start()

---

在config使用variables关键字和在step使用with_variables定义变量

import sys
from pathlib import Path
import pytest
sys.path.insert(0, str(Path(__file__).parent.parent))


from httprunner import HttpRunner, Config, Step, RunRequest, RunTestCase
from httprunner import Parameters


class TestCaseBattle(HttpRunner):

    config = (
        Config("battle: login")
        .variables(
            **{
                "username": "gsky",
                "password": "gsky",
            }
        )
        .base_url("http://xxx.xx.xx.225:12356")
        .verify(False)
    )

    teststeps = [

        Step(
            RunRequest("post form data")
            .with_variables(**{"res":"please select One Equipment"})
            .post("/login")
            .with_data({"username":"$username","password":"$password"})
            .validate()
            .assert_equal("status_code", 200)
            .assert_regex_match("body", "${res}")
        ),
    ]


if __name__ == "__main__":
    TestCaseBattle().test_start()

使用Parameters参数化

独立参数

代码

    @pytest.mark.parametrize(
        "param", Parameters({"equipmentid": ["10001","10002","10003"]})
    )
    def test_start(self, param):
        super().test_start(param)

关联参数-直接枚举

代码

    @pytest.mark.parametrize(
        "param",
        Parameters(
            {"enemyid-equipmentid-res": [
                   ["20001", "10002","You win Level 1"],
                   ["20001", "10001","Your and your enemy all dead!!!"],
                   ["", "10002","Error 9904: Your kill yourself!!"],
                   ["20004", "","Error 9905: Your fight your enemy by nothing!And you are  died!"],
                ]}
        ),
    )
    def test_start(self,param):
        super().test_start(param)

关联参数-生成笛卡尔积

各个参数会以笛卡尔积的方式组合.
下面会组合成四条测试用例
['gsky','gsky'],['gsky','gsky123'],['gsky123','gsky],['gsky123','gsky123]

import sys
from pathlib import Path
import pytest
sys.path.insert(0, str(Path(__file__).parent.parent))


from httprunner import HttpRunner, Config, Step, RunRequest, RunTestCase
from httprunner import Parameters


class TestCaseBattle(HttpRunner):
   
    @pytest.mark.parametrize(
        "param",
        Parameters(
            {"username":["gsky","gsky123"],"password":["gsky","gsky123"]}
        ),
    )
    def test_start(self,param):
        super().test_start(param)
        
    config = (
        Config("battle: login")
        .base_url("http://xxx.xx.xx.225:12356")
        .verify(False)
    )

    teststeps = [

        Step(
            RunRequest("post form data")
            .with_variables(**{"res":"please select One Equipment"})
            .post("/login")
            .with_data({"username":"$username","password":"$password"})
            .validate()
            .assert_equal("status_code", 200)
            .assert_regex_match("body", "${res}")
        ),
    ]


if __name__ == "__main__":
    TestCaseBattle().test_start()

使用csv文件枚举所有场景

使用csv文件参数化.对于项目来说,应该支持:

1. 在测试用例里写入csv文件绝对路径
2. 从环境变量里,拿到csv文件的绝对路径,测试用例里只写环境变量的name
   最好的实践是第二种方式.

不建议在测试文件中使用csv文件的相对路径,使用相对路径的话修改起来非常麻烦, 因此,框架改动后也就不支持这种方式.

对于csv文件参数化,需要修改源码.
loader.py中,csv_file = os.path.join(project_meta.RootDir, *csv_file.split("/"))注释掉,改为从.env文件中获取csv文件路径

        # make compatible with Windows/Linux  
        # csv_file = os.path.join(project_meta.RootDir, *csv_file.split("/"))
        try:
            temp = os.getenv(csv_file)
        except IOError:
            print('.evn文件中的环境变量account_path不存在')
        else:
            csv_file = temp

csv文件:

代码

import sys
from pathlib import Path
import pytest
sys.path.insert(0, str(Path(__file__).parent.parent))

from httprunner import HttpRunner, Config, Step, RunRequest, RunTestCase
from httprunner import Parameters


class TestCaseBattle(HttpRunner):
    
    @pytest.mark.parametrize(
        "param",
        Parameters(
            {"username-password-res":"${P(battle_cases/account.csv)}"}
        ),
    )
    def test_start(self,param):
        super().test_start(param)

    config = (
        Config("battle: login")
		.base_url("http://xx.xx.xx.xx:12356")
        .verify(False)
    )

    teststeps = [

        Step(
            RunRequest("post form data")
            .post("/login")
            .with_data({"username":"$username","password":"$password"})
            .validate()
            .assert_equal("status_code", 200)
            .assert_regex_match("body", "${res}")

        ),
    ]


if __name__ == "__main__":
    TestCaseBattle().test_start()

执行结果
