Pytest 参数化

Pytest中装饰器@pytest.mark.parametrize(‘参数名’, list)

方式1：
使用py文件存放测试数据。

login_data.py

def login_data_list():
	login_data_list = [
    	{'username': '', 'password': 'xxxx', 'expect': '账号为空'},
    	{'username': 'xxxx', 'password': '', 'expect': '密码为空'},
    	{'username': 'xxxx', 'password': 'xxxxx', 'expect': '无效的用户名或密码。'},
	]
	return login_data_list

test_login.py

import pytest
from page_objects.login import Login
from data.login_data import login_data_list
from page_locators.login_page import LoginPage


@pytest.mark.parametrize('test_data', login_data_list())
@pytest.mark.usefixtures('geturl')
def test_sing_in_failed(self, browser, test_data):     
   username = login['username']
   password = login['password']
   expected = login['expect']
   
   try:
      LoginPage.user_login(browser, username, password)
      actual = LoginPage(browser).error_text()
      assert actual == expect
      
   except Exception as e:
      raise e

方式2：
使用yaml存放测试数据，读取yaml文件数据

test_data.yaml

login_data1:
  username: 
  password: xxxxx

login_data2:
  username: xxxxx
  password:

@pytest.mark.parametrize('test_data', YamlUtil(os.getcwd() + '/test_data.yaml').read_yaml().values())
@pytest.mark.usefixtures('geturl')  
def test_sing_in_failed(self, browser, test_data):
    username = test_data['username']
    password = test_data['password']

    LoginPage.user_login(browser, username, password)

方式3：

与第2种方式类似，视实际情况使用。

test_data.yaml

- user: username1
  pwd: 'xxxxx'

- user: username2
  pwd: 'xxxxx'

- user: username3
  pwd: 'xxxxx'

@pytest.mark.parametrize('login', YamlUtil(os.getcwd() + '/test_data.yaml').read_yaml())
@pytest.mark.usefixtures('geturl')  
def test_sign_in_failed(self, browser, login):
    usr = login['user']
    pwd = login['pwd']
    LoginPage.user_login(browser, usr, pwd)
