#在unittest.TestCase中6个常用的断言方法

unittest.TestCase.assertEqual(a,b)#核实a==b
unittest.TestCase.assertNotEqual(a,b)#核实a!=b
unittest.TestCase.assertTrue(x)#核实x为True
unittest.TestCase.assertFalse(x)#核实x为False
unittest.TestCase.assertIn(item,list)#核实item在list中
unittest.TestCase.assertNotIn(item,list)#核实item不在list中

#setUp(),如果在TestCase类中包含setUp()方法，Python将先运行它，再运行其他以test开头的方法
#方法setUp()，让测试方法编写起来更容易，可在setUp()中，创建一系列实例并设置他们的属性，再在其他方法中使用这些实例
