selenium 自动化测试工具（五）UnitTest介绍

# encoding = utf - 8
import unittest

# 被测试类
class myclass(object):
	@classmethod
	def sum(cls,a,b):
		return a + b   #将两个传入参数进行相加操作
	@classmethod
	def sub(cls, a, b):
		return a - b   #将两个传入参数进行相减操作

class mytest(unittest.TestCase):
	# @classmethod
	# def setUpClass(cls):
	# 	print('setUpClass方法')

	# @classmethod
	# def tearDownClass(cls):
	# 	print('tearDownClass方法')

	# def setUp(self):
	# 	self.a=3
	# 	self.b=1
	# 	print('setUp方法')
	# def tearDown(self):
	# 	print('tearDown方法')
	#具体的测试用例，一定要以test开头

	a = 3
	b = 1
	def test_2sum(self):
		self.assertEqual(myclass.sum(self.a,self.b), 4, 'test sum fail')
		print("test2sum")

	@unittest.skip('跳过这条用例')
	def test_1sub(self):
		#断言两数之差的结果是否是2
		self.assertEqual(myclass.sub(self.a,self.b),2,'test sub fail')
		print('test1sub')

class aa(unittest.TestCase):
	def testaa(self):
		# test=1/0
		print('testaa')

if __name__=='__main__':
	# unittest.main()

	#使用测试集合可以同时执行同一个 py文件中的测试用例
	# testCase=unittest.TestLoader().loadTestsFromTestCase(mytest)
	# testCase1 = unittest.TestLoader().loadTestsFromTestCase(aa)
	# 将多个测试类加载到集合中
	# suite=unittest.TestSuite([testCase,testCase1])
	# unittest.TextTestRunner().run(suite)

	# 1）获取TestSuite的实例对象
	suite = unittest.TestSuite()
	# 2）讲测试用例添加到测试容器中
	suite.addTest(mytest("test_1sub"))
	suite.addTest(aa('testaa'))
	suite.addTest(mytest("test_2sum"))
	# 3）创建TextTestRunner类的实例对象
	runner = unittest.TextTestRunner(verbosity=2)
	runner.run(suite)
