ddt方法介绍

import unittest
from ddt import ddt,data,unpack
from src.utils.ReadExcel import ReadExcel


@ddt
class Testddt2(unittest.TestCase):
    def setUp(self):
        pass

    '''
    *的作用类似于将原始数据的最外层括号拿掉，例如我们的原始数据是：
    [['123456', 111], ['111', 'aaa'], ['123458', 'aaa'], ['123459', 'aaa']]
    加上*之后变成：
    ['123456', 111], ['111', 'aaa'], ['123458', 'aaa'], ['123459', 'aaa']
    然后可使用@unpack读取值，参数两位,运行结果：
        123456 111
        111 aaa
        123458 aaa
        123459 aaa
    '''
    #调用ReadExcel类中的get_data()方法获取数据

    @data(*ReadExcel().get_data())
    @unpack
    def test_1(self, username, password, message):
        print()
        print(username, password, message)

    '''
    不加*，不拆包时运行结果：
    [['123456', 111.0], ['111', 'aaa'], ['123458', 'aaa'], ['123459', 'aaa']]
    '''
    @data(ReadExcel().get_data())
    def test_2(self, value):
        print()
        print("---test_2---")
        print(value)
    '''
    不加*，使用@unpack时，运行结果：
    ['123456', 111.0] ['111', 'aaa'] ['123458', 'aaa'] ['123459', 'aaa']
    '''
    @data(ReadExcel().get_data())
    @unpack
    def test_3(self, value1, value2, value3, value4):
        print()
        print("---test_3---")
        print(value1, value2, value3, value4)
