pytest + python project preliminary practice

Introduction: In use unittest framework, found two drawbacks:

1, unittest have to reopen the browser each test case is executed, can not be achieved disposable loading browser to perform all use cases (eg: Login - to "implement all use cases -" Exit);

2, unittest framework limitations, driver modules can span py.

To solve this problem, then went to study the pytest framework and made a preliminary practice, if badly written, but please enlighten!

 

Scene and steps:

1, log (need to enter a user name, password and click the login button; for login results after a successful login)

2, the new user (new user can log on later)

3, close the browser

 

A, pytest installation

1, the installation

Command: pip install -U pytest

 2, view the version

Command: pip show pytest

 

Second, write code

1, the project directory

case: storage of test cases

common: public file storage

page: page Business Package

 2, base.py files, basic operations of packaging

# -*- coding=utf-8 -*-
from selenium.webdriver.support.ui import WebDriverWait
from selenium import webdriver
from selenium.webdriver.support import expected_conditions as EC
from selenium.common.exceptions import TimeoutException



class Base(object):

    def __init__(self, driver):
        self.driver = driver

    def find(self, locator):
        """locator = ("id","kw")，查找某元素"""
        try:
            element = WebDriverWait(self.driver, 10, 1).until(lambda x: x.find_element(*locator))
            return element
        except TimeoutException as msg:
            print("元素不存在")

    def send(self, locator, text):
        """输入框传值，元素不存在时跳过执行"""
        try:
            self.find(locator).clear()
            self.find(locator).send_keys(text)
        except TimeoutException as msg:
            # print("元素不存在",msg)
            pass

    def click(self,locator):
        """点击事件"""
        self.find(locator).click()

3、login.py  文件，登录的业务代码

# -*- coding=utf-8 -*-
from selenium import webdriver
import time
from common.base import Base


class Login(Base):

    def login(self, username, password):
        """登录"""
        user = ('name', 'loginName')
        self.send(user, username)
        pwd = ('name', 'loginPassWord')
        self.send(pwd, password)
        submit = ('id', 'loginBtn')
        self.click(submit)
        time.sleep(2)
        content = ('id', 'title')
        res = self.find(content).text
        print('已成功登录', res)


if __name__ == '__main__':
    driver = webdriver.Chrome()
    url = ""
    driver.get(url)

4、adduser.py  文件  登录后添加用户的业务代码

# -*- coding=utf-8 -*-
from selenium import webdriver
import time
from common.base import Base
import time


class AddUser(Base):

    def add_user(self, user, phone, password, repassword):
        """登录后添加用户"""
        yonghu = ('id', 'uname')
        self.send(yonghu, user)
        shouji = ('id', 'uphone')
        self.send(shouji, phone)
        mima = ('id', 'password')
        self.send(mima, password)
        remima = ('id', 'password2')
        self.send(remima, repassword)
        time.sleep(1)
        button = ('id', 'savebtn2')
        self.click(button)


if __name__ == '__main__':
    driver = webdriver.Chrome()
    url = ""
    driver.get(url)

5、conftest.py  文件

# -*- coding=utf-8 -*-
import pytest
from selenium import webdriver
from page.login import Login
import time


@pytest.fixture(scope='session')
def driver():
    global _driver
    print('------------open browser------------')
    _driver = webdriver.Chrome()
    _driver.maximize_window()
    _driver.implicitly_wait(10)
    yield _driver
    print('------------close browser------------')
    _driver.quit()


@pytest.fixture(scope='session')
def login(driver):
    """登录"""
    url = "登录的url地址"
    driver.get(url)
    time.sleep(5)
    login_system = Login(driver)
    login_system.login("13166666666", "666666")
    yield
    driver.delete_all_cookies()

6、测试用例文件：test_user_one.py、test_user_two.py ，两个文件内容一样，只是模拟两个用例。

import pytest
from page.adduser import AddUser


class TestOne(object):

    def test_01(self, login, driver):
        url = "新增用户页面的url地址"
        driver.get(url)
        user = AddUser(driver)
        user.add_user('test', '13122222224', '666666', '666666')


if __name__ == '__main__':
    pytest.main(["-s", "test_user_one.py"])

 

三、运行测试用例

1、进入项目根目录

2、输入命令：

pytest case  (运行多个测试用例)

pytest  case/test_user_one.py (运行单个用例)
