45. 数据驱动parametrize

参数化可以组装测试数据，在测试前定义好测试数据，并在测试用例中使用
# 单参数循环
@pytest.mark.parametrize("a",["b","c"])
def test_parametrize(a):
    print(a)

# 多参数循环
@pytest.mark.parametrize("a,b",[("c","d"),("e","f")])
def test_parametrize(a,b):
    print(a,b)

单参数循环

import pytest

# 单参数单次循环
@pytest.mark.parametrize("key",["value"])
def test_parametrize01(key):
    print(key)

if __name__=="__main__":
    pytest.main()

import pytest

# 单参数，多次循环
@pytest.mark.parametrize("key",["value1","value2","value3"])
def test_parametrize01(key):
    print(key)

if __name__=="__main__":
    pytest.main()

from time import sleep

import pytest

# 单参数，单次循环
# @pytest.mark.parametrize("key",["value"])
# def test_parametrize01(key):
#     print(key)

# 单参数，多次循环。数组里面有几组数据，循环几次
# @pytest.mark.parametrize("test", ['接口自动化', 'UI自动化', '性能测试'])
# def test_parametrize02(test):
#     assert test == "接口自动化"
from selenium.webdriver.common.by import By

from utils.read import read_yaml


@pytest.mark.parametrize("key", read_yaml()['skill'])
def test_baidu(driver, key):
    driver.get("https://www.baidu.com/")
    driver.find_element(By.ID, 'kw').send_keys(key)
    driver.find_element(By.ID, 'su').click()
    sleep(1)

多参数循环, 常用于登录、注册场景

from time import sleep

import allure
import pytest
from selenium.webdriver.common.by import By
from utils.read import read_yaml

heros = [("安琪拉", "我的小熊去哪里了"), ("后裔", "周日被我射熄火了")]

# 多参数多次循环
@pytest.mark.parametrize("hero,word", heros)
def test_parametrize02(hero, word):
    print("{}的台词是{}".format(hero, word))


@pytest.mark.parametrize("key,value", [["安琪拉", "拉"], ["后裔", "后"]])
def test_parametrize(key, value):
    assert value in key


# @pytest.mark.parametrize("data", read_yaml()['userinfos'])
# def test_login(driver, data):
#     driver.get("http://sellshop.5istudy.online/sell/user/login_page")
#     driver.find_element(By.ID, 'username').send_keys(data['username'])
#     driver.find_element(By.ID, 'password').send_keys(data['password'])
#     driver.find_element(By.CSS_SELECTOR, '#login > form > p.login.button > input[type=submit]').click()
#     sleep(2)

@pytest.mark.parametrize("username,password", read_yaml()['userinfo_list'])
def test_login(driver, username,password):
    driver.get("http://sellshop.5istudy.online/sell/user/login_page")
    driver.find_element(By.ID, 'username').send_keys(username)
    driver.find_element(By.ID, 'password').send_keys(password)
    driver.find_element(By.CSS_SELECTOR, '#login > form > p.login.button > input[type=submit]').click()
    if username == 'admin':
        text = driver.find_element(By.CSS_SELECTOR,"body > div > div > div > div > strong").text
        assert text == "用户不存在"
    sleep(2)

参数值为字典形式

# 参数值为字典形式
@pytest.mark.parametrize("hero",[{"name":"安琪拉"}])
def test_parametrize(hero):
    print(hero["name"])

import pytest


@pytest.mark.parametrize("data", [{"name": "安琪拉", "word": "火焰是我最喜欢的玩具"}])
def test_parametrize03(data):
    print(data["name"])
    print(data["word"])
