Selenium2+python自動化之數據驅動（ddt）

環境准備

1.安裝ddt模塊，打開cmd輸入pip install ddt在線安裝

數據驅動原理

1.測試數據為多個字典的list類型

2.測試類前加修飾@ddt.ddt

3.case前加修飾@ddt.data()

4.運行后用例會自動加載成三個單獨的用例

# coding:utf-8
import ddt
import unittest

# 測試數據
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)

 selenium數據驅動案例

以登錄的方法為例子：

從上一篇封裝的excel方法里面讀取數據，作為測試數據：http://www.cnblogs.com/lingzeng86/p/6793398.html（就是導入的excelunit包）

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

# 測試數據
data = excelunit.ExcelUtil("test.xlsx", "Sheet2")
testData = data.dict_data()
print testData


@ddt.ddt
class Bolg(unittest.TestCase):
    """登錄博客"""
    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):
        """登錄方法,賬號和密碼參數化"""
        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):
        """判斷是否獲取到登錄賬戶名稱"""
        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):
        """登錄案例參考"""
        print ("當前測試數據%s" % data)
        # 調用登錄方法
        self.login(data["username"], data["password"])
        # 判斷結果
        result = self.is_login_sucess()
        self.assertTrue(result)

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