參數化和數據驅動的概念這個肯定要知道的，參數化的思想是代碼用例寫好了后，不需要改代碼，只需維護測試數據就可以了，并且根據不同的測試數據生成多個用例 python里面用unittest框架 ~~~ import unittest import ddt # 測試數據 datas = [ {"user": "admin", "psw": "123", "result": "true"}, {"user": "admin1", "psw": "1234", "result": "true"}, {"user": "admin2", "psw": "1234", "result": "true"}, {"user": "admin3", "psw": "1234", "result": "true"}, {"user": "admin4", "psw": "1234", "result": "true"}, {"user": "admin5", "psw": "1234", "result": "true"}, {"user": "admin6", "psw": "1234", "result": "true"}, {"user": "admin7", "psw": "1234", "result": "true"}, {"user": "admin8", "psw": "1234", "result": "true"}, {"user": "admin9", "psw": "1234", "result": "true"}, {"user": "admin10", "psw": "1234", "result": "true"}, {"user": "admin11", "psw": "1234", "result": "true"}] @ddt.ddt class Test(unittest.TestCase): @ddt.data(*datas) def test_(self, d): """上海-悠悠：{0}""" print("測試數據：%s" % d) if __name__ == "__main__": unittest.main() ~~~ unittest框架還有一個paramunittest也可以實現 ~~~ import unittest import paramunittest import time # python3.6 # 作者：上海-悠悠 @paramunittest.parametrized( {"user": "admin", "psw": "123", "result": "true"}, {"user": "admin1", "psw": "1234", "result": "true"}, {"user": "admin2", "psw": "1234", "result": "true"}, {"user": "admin3", "psw": "1234", "result": "true"}, {"user": "admin4", "psw": "1234", "result": "true"}, {"user": "admin5", "psw": "1234", "result": "true"}, {"user": "admin6", "psw": "1234", "result": "true"}, {"user": "admin7", "psw": "1234", "result": "true"}, {"user": "admin8", "psw": "1234", "result": "true"}, {"user": "admin9", "psw": "1234", "result": "true"}, {"user": "admin10", "psw": "1234", "result": "true"}, {"user": "admin11", "psw": "1234", "result": "true"}, ) class TestDemo(unittest.TestCase): def setParameters(self, user, psw, result): '''這里注意了，user, psw, result三個參數和前面定義的字典一一對應''' self.user = user self.user = psw self.result = result def testcase(self): print("開始執行用例：--------------") time.sleep(0.5) print("輸入用戶名：%s" % self.user) print("輸入密碼：%s" % self.user) print("期望結果：%s " % self.result) time.sleep(0.5) self.assertTrue(self.result == "true") if __name__ == "__main__": unittest.main(verbosity=2) ~~~ 如果用的是pytest框架，也能實現參數化 ~~~ # content of test_canshu1.py # coding:utf-8 import pytest @pytest.mark.parametrize("test_input,expected", [ ("3+5", 8), ("2+4", 6), ("6 * 9", 42), ]) def test_eval(test_input, expected): assert eval(test_input) == expected if __name__ == "__main__": pytest.main(["-s", "test_canshu1.py"]) ~~~ pytest里面還有一個更加強大的功能，獲得多個參數化參數的所有組合，可以堆疊參數化裝飾器 ~~~ import pytest @pytest.mark.parametrize("x", [0, 1]) @pytest.mark.parametrize("y", [2, 3]) def test_foo(x, y): print("測試數據組合：x->%s, y->%s" % (x, y)) if __name__ == "__main__": pytest.main(["-s", "test_canshu1.py"]) ~~~
