Selenium2+python自动化之数据驱动（ddt）

环境准备

1.安装ddt模块，打开cmd输入pip install ddt在线安装

数据驱动原理

1.测试数据为多个字典的list类型

2.测试类前加修饰@ddt.ddt

3.case前加修饰@ddt.data()

4.运行后用例会自动加载成三个单独的用例

# coding:utf-8
import ddt
import unittest

# 测试数据
test_data1 = [{"username": "zhangsan", "pwd": "zhangsan"},
             {"username": "lisi", "pwd": "lisi"},
             {"username": "wangwu", "pwd": "wangwu"},
             ]
test_data2 = [{"username": "wukong", "pwd": "wukong"},
             {"username": "wuneng", "pwd": "woneng"},
             {"username": "wujing", "pwd": "wujing"},
             ]



@ddt.ddt
class Test(unittest.TestCase):
    def setUp(self):
        print("Start!")

    def tearDown(self):
        print("end!")

    @ddt.data(*test_data1)
    def test_ddt1(self, data):
        print(data)

    @ddt.data(*test_data2)
    def test_ddt2(self, data):
        print(data)


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

 selenium数据驱动案例

以登录的方法为例子：

从上一篇封装的excel方法里面读取数据，作为测试数据：http://www.cnblogs.com/lingzeng86/p/6793398.html（就是导入的excelunit包）

# coding:utf-8
import ddt
import time
import excelunit
import unittest
from selenium import webdriver

# 测试数据
data = excelunit.ExcelUtil("test.xlsx", "Sheet2")
testData = data.dict_data()
print testData


@ddt.ddt
class Bolg(unittest.TestCase):
    """登录博客"""
    def setUp(self):
        self.driver = webdriver.Chrome()
        url = "https://passport.cnblogs.com/user/signin"
        self.driver.get(url)
        self.driver.implicitly_wait(10)

    def login(self, username, psw):
        """登录方法,账号和密码参数化"""
        self.driver.find_element_by_id("input1").send_keys(username)
        self.driver.find_element_by_id("input2").send_keys(psw)
        self.driver.find_element_by_id("signin").click()
        time.sleep(3)

    def is_login_sucess(self):
        """判断是否获取到登录账户名称"""
        try:
            text = self.driver.find_element_by_id("lnk_current_user").text
            print text
            return True
        except:
            return False

    @ddt.data(*testData)
    def test_login(self, data):
        """登录案例参考"""
        print ("当前测试数据%s" % data)
        # 调用登录方法
        self.login(data["username"], data["password"])
        # 判断结果
        result = self.is_login_sucess()
        self.assertTrue(result)

    def tearDown(self):
        self.driver.quit()


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