作用:将字典进行解包,输出测试用例中的单个字段的值
def unpack(func):
func.unpack = True
return func
def create_test_method(method, value):
# todo 闭包函数作用是将测试方法和函数放到闭包中,进行数据锁定
def wrapper(self):
# todo unpack装饰器的实现
if hasattr(method, 'unpack'):
if isinstance(value, dict):
method(self, **value)
else:
method(self, *value)
else:
method(self, value)
return wrapper
test_datas=[ {'id':1,'title':'测试用例1'}, {'id':2,'title':'测试用例2'}, {'id':3,'title':'测试用例3'}, {'id':4,'title':'测试用例4'} ] from test_ddt import ddt,data,json_file,yaml_file,unpack import unittest @ddt class TestDemo(unittest.TestCase): @unpack @data(*test_datas) def test_demo(self,id,title): print('测试用例执行',id,title)
测试用例执行 1 测试用例1
测试用例执行 2 测试用例2
测试用例执行 3 测试用例3
测试用例执行 4 测试用例4
test_datas=[ {'id':1,'title':'测试用例1'}, {'id':2,'title':'测试用例2'}, {'id':3,'title':'测试用例3'}, {'id':4,'title':'测试用例4'} ] from test_ddt import ddt,data,json_file,yaml_file,unpack import unittest @ddt class TestDemo(unittest.TestCase): @data(*test_datas) def test_demo(self, item): print('测试用例执行', item)
测试用例执行 {‘id’: 1, ‘title’: ‘测试用例1’}
测试用例执行 {‘id’: 2, ‘title’: ‘测试用例2’}
测试用例执行 {‘id’: 3, ‘title’: ‘测试用例3’}
测试用例执行 {‘id’: 4, ‘title’: ‘测试用例4’}
作用:测试数据编写在json文件中,读取测试数据用于测试
def json_file(file_path): ''' :param file_path: json文件路径 :return: ''' def wrapper(func): try: with open(file_path, "r", encoding="utf-8") as f: datas = json.load(f) except: with open(file_path, "r", encoding="gbk") as f: datas = json.load(f) if not isinstance(datas, list): raise ValueError('json文件内的用例数据格式不符护规范') func.datas = datas return func return wrapper
from test_ddt import ddt,data,json_file,yaml_file,unpack import unittest @ddt class TestDemo(unittest.TestCase): # @unpack # @data(*test_datas) # def test_demo(self,id,title): # print('测试用例执行',id,title) # @data(*test_datas) # def test_demo(self, item): # print('测试用例执行', item) @json_file(r'D:\project_development\测试开发\day5_unittest框架用例参数化库ddt的使用\data.json') def test_demo1(self,item): print('测试用例执行',item)
