unittest框架:
- 丰富的断言类型
- 自动化测试
- 测试报告
unittest框架的下载
在python3中unittest是内置模块
1.自定义的类必须继承TestCase,执行run函数,则会自动找以methodName指定的方法名并执行,默认名字为 runTest
from unittest import TestCase from case_set import CaseSet class MineCase(TestCase): def runTest(self): code = CaseSet().get_status_code() self.assertEqual(code, 200, '实际值是:{},预期值是:{}'.format(code, 200)) if __name__ == '__main__': MineCase().run()
2.每个用例在执行之前会执行setUp函数,在每个用例执行之后会执行tearDown函数
3.unittest中有很多断言可以用
-assertIn(a,b,msg):a如果不在b中报错
-assertIs(a, b, msg):a is not b报错
-assertEqual(a, b, msg): a不等于b报错
-assertNotEqual(a, b, msg): a等于b报错
-assertTrue(x, msg):表达式x为False,报错
-assertFalse(x, msg):表达式x为True,报错
- ...
4.unittest中执行脚本的另一种方式
- 在类中定义方法名以test为开头
- 执行unittest.main()
5. self._testMethodName:用例函数名 self._testMethodDoc:用力函数的描述注释
6. TestSuite:测试套件,可以理解为一个盒子,包含多个测试用例
使用步骤:
-实例化所有的用例
-创建一个盒子
-将用例放在盒子中
-使用执行器执行盒子中的用例
代码如下:
class MineCase1(TestCase): def test_case_001(self): self.assertTrue("Foo".isupper()) def test_case_002(self): self.assertTrue('foo'.islower()) if __name__ == '__main__': # 实例化用例 case1 = MineCase1(methodName="test_case_001") case2 = MineCase1(methodName="test_case_002") # 创建容器 suite = unittest.TestSuite() # 将用例放入容器中 suite.addTests([case1, case2]) # 使用执行器执行 runner = unittest.TextTestRunner() runner.run(suite)
7.makeSuite:在实例化suite的时候,同时完成收集用例
1 2 3 4 5 6 7 8 9 10 11 12 | class MineCase1(TestCase): def test_case_001( self ): self .assertTrue( "Foo" .isupper()) def test_case_002( self ): self .assertTrue( 'foo' .islower()) if __name__ = = '__main__' : suite = unittest.makeSuite(testCaseClass = MineCase1, prefix = "test" ) runner = unittest.TextTestRunner() runner.run(suite) |
8. suite = unittest.TestLoader().loadTestsFromModule(模块名字):发现一个模块中的所有继承TestCase且以test为开头的用例
suite = unittest.TestLoader().loadTestsFromTestCase(类名):发现指定类中中以test为开头的用例
9.suite = unittest.TestLoader().discover(start_dir='',
pattern='test*.py',
top_level_dir=None)
递归查找起始目录start_dir下,所有以test开头的模块中的继承TestCase且以test为开头的用例
注意:top_level_dir >= start_dir
10. verbosity:用来控制执行器用例输出详细程度
-0: 精简模式
-1:默认模式,输出用例执行结果
-2: 详细模式,输出用例来自哪个模块下以及执行结果 推荐
runner = unittest.TextTestRunner(verbosity=2)
11. setupClass & tearDownClass:在所有用例执行之前执行有且一次,在所有用例执行之后有且执行一次
代码
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 | class MineCase1(TestCase): @classmethod def setUpClass( cls ) - > None : print ( "用例执行之前,只执行一次" ) @classmethod def tearDownClass( cls ) - > None : print ( "用例执行之后,只执行一次" ) def setUp( self ) - > None : print ( "before用例执行之前" ) def tearDown( self ) - > None : print ( "after用例执行之后" ) def test_case_001( self ): self .assertTrue( "FOO" .isupper()) def test_case_002( self ): self .assertTrue( 'foo' .islower()) if __name__ = = '__main__' : suite = unittest.TestLoader().loadTestsFromTestCase(MineCase1) runner = unittest.TextTestRunner(verbosity = 2 ) runner.run(suite) |
打印结果
用例执行之前,只执行一次
before用例执行之前
after用例执行之后
before用例执行之前
after用例执行之后
用例执行之后,只执行一次
12. 跳过用例
-unittest.skip(reason)
-unittest.skipif(condition,reason)
代码:
class MineCase1(TestCase): @unittest.skip(reason="无条件跳过") def test_case_001(self): self.assertTrue("FOO".isupper()) @unittest.skipIf(condition=10 > 2, reason="跳过") def test_case_002(self): self.assertTrue('foo'.islower()) def test_case_003(self): self.assertTrue('foo'.islower()) if __name__ == '__main__': unittest.main(verbosity=2)
13. 将执行结果放入文本中:创建执行器指定stream文件流
代码
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 | class MineCase1(TestCase): def test_case_001( self ): self .assertTrue( "FOO" .isupper()) def test_case_002( self ): self .assertTrue( 'foo' .islower()) def test_case_003( self ): self .assertTrue( 'foo' .islower()) if __name__ = = '__main__' : suite = unittest.makeSuite(testCaseClass = MineCase1, prefix = "test" ) with open ( 'a.txt' , "w" , encoding = "utf-8" ) as fd: runner = unittest.TextTestRunner(verbosity = 2 , stream = fd) runner.run(suite) |
14. 生成测试报告:借助 HTMLTestRunner模块来实现
该 HTMLTestRunner为非官方,所以不能pip下载,文件代码,在项目中HTMLTestRunner.py中(适用于python3)
代码:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 | from HTMLTestRunner import HTMLTestRunner class MineCase1(TestCase): # @unittest.skip(reason="无条件跳过") def test_case_001( self ): self .assertTrue( "FOO" .isupper()) @unittest .skipIf(condition = 10 < 2 , reason = "跳过" ) def test_case_002( self ): self .assertTrue( 'foo' .islower()) def test_case_003( self ): self .assertTrue( 'foo' .islower()) if __name__ = = '__main__' : suite = unittest.makeSuite(testCaseClass = MineCase1, prefix = "test" ) with open ( 'a.html' , "wb" ) as fd: runner = HTMLTestRunner(stream = fd, verbosity = 2 , title = "自动化测试结果" , description = "ATA 测试结果" ) runner.run(suite) |
1 | HTMLTestRunner.py |

15.addCleanup
-
addCleanup可在case执行过程的任何地方进行添加清理函数,比如setUp,tearDown或者case中;
- 正常情况下不需要主动调用,每个case执行结束都会执行添加的清理函数,添加函数执行顺序(后进先出);
- 哪个用例添加的,只会在该用例中调用清理函数,其他的用力不会调用
- tearDown与addCleanup可以结合使用,两者并不冲突;相对来说addCleanup使用起来更加灵活,可以在用例运行中执行;
16.doCleanups
- 它负责调用addCleanup() 添加的所有清除函数;
- doCleanups() 一次将方法从清理函数的堆栈中弹出,因此可以随时调用它;
- setUp() 引发异常的情况下无条件调用此方法;
17.addClassCleanup
优先级在tearDownClass之后,也只会执行一次
18.doClassCleanups
执行之前添加所有添加的清理函数
