DDT:数据驱动测试
pip install ddt
实现DDT的步骤：
1、在测试类上使用@ddt装饰符
2、在测试方法上使用@data装饰符
3、@data 把参数当作 测试数据，参数可以是单个值，列表，元组，字典
4、将传入的列表解析（折包）使用@unpack
from ddt import ddt,data,unpack
import unittest
@ddt
class TestDdt(unittest.TestCase):
@unittest.skip
@data('你好', '1', 'hello')
def test_var(self, value):
print(value)
assert '你好' == value
@unittest.skip
@data([2],[1])
@unpack
def test_list(self, value):
print(value)
assert 3 == value +1
@unittest.skip
@data((1, 2), (2, 3))
@unpack
def test_tuple(self, value1, value2):
print(value1, value2)
assert value2 == value1 + 1
@unittest.skip
@data({'first': 1, 'second': 3, 'third': 5},
{'first': 4, 'second': 7, 'third': 8})
@unpack
def test_dicts(self, first, second, third):
self.assertTrue(first < second < third)
@data({'name':'linda','age':'18'})
@unpack
def test_dict1(self,name,age):
print(name,age)
if __name__ == '__main__':
unittest.main()
