初识unittest

unittest介绍：

　　unitest是python版本的junit测试框架，支持测试自动化、共享测试设置和关闭代码，测试用例组合管理及生成对应的测试报告

unittest四大功能：

test fixture

A test fixture represents the preparation needed to perform one or more tests, and any associate cleanup actions. This may involve, for example, creating temporary or proxy databases, directories, or starting a server process.

　　支持一个或多个的测试组件，以及清除测试动作，例如：创建或临时数据库链接，目录及启动服务器进程等操作。

test case

A test case is the smallest unit of testing. It checks for a specific response to a particular set of inputs. unittest provides a base class, TestCase, which may be used to create new test cases.

　　测试用例是测试的各个单元，检查了一个特定输入的响应，unittest提供了一个基类，TestCase用于创建新的测试用例。

test suite

A test suite is a collection of test cases, test suites, or both. It is used to aggregate tests that should be executed together.

　　一个测试套件是测试案例，测试套件，或两者的集合。它用于汇总应一起执行的测试。

test runner

A test runner is a component which orchestrates the execution of tests and provides the outcome to the user. The runner may use a graphical interface, a textual interface, or return a special value to indicate the results of executing the tests.

　　测试运行可以使用命令窗口或者界面运行特定的测试用例，返回对应的测试结果

unittest的第一个例子：

import unittest

class TestNumMethod(unittest.TestCase):

    def test_one(self):
        self.assertIn(2,[1,2,3])
        
    def test_two(self):
        self.assertEqual("1",1)

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