UnitTest框架管理测试用例——python自动化测试

UnitTest框架

UnitTest是Python自带一个单元测试框架，常用它来做单元测试。

注意:对于测试来说，UnitTest框架的作用是自动化脚本(用例代码)执行框架————(使用UnitTest框架来管理运行多个测试用例的)

为什么使用UnitTest框架

能够组织多个用例去执行
提供丰富的断言方法(让程序代码判断代替人工自动的判断预期结果与实际结果是否相符)
能够生成测试报告

UnitTest框架的组成

TestCase(最核心的模块)

TestCase(测试用例)，每一个TestCase(测试用例)都是一个代码文件，在这个代码文件中来书写真正的用例代码。

TestSuite

TestSuite(测试套件)，TestSuite用来管理，组装(打包)多个TestCase(测试用例)的。

TestRunner

TestRunner(测试执行，测试运行),TestRunner用来执行TestSuite(测试套件)的。

TestLoader

TestLoader(测试加载)，TestLoader用来管理，组装(打包)多个TestCase(测试用例)的,TestLoader是对TestSuit(测试套件)功能的补充。

Fixture

Fixture(测试夹层),Fixture是书写在TestCase(测试用例)的代码中，是一个代码结构，可以在每个方法执行前后都会执行的内容。

在这里插入图片描述

如上图,蓝色的方框就是一个方法(函数),该方法在执行前后都会执行Fixture的内容。

测试结果的查看

在这里插入图片描述

如上图紫色方框所示，四个点表示四个测试用例(测试方法)全部通过。

.表示测试用例通过。
F 表示测试用例未通过。
E 表示测试用例代码有问题。

TestCase(测试用例)的书写

TestSuite(测试套件)与TestRunner(测试运行)的书写

TestLoader(测试加载)的书写

Fixture(测试夹具)的书写

Fixture是一种代码结构，在某些特定情况下会自动执行。

方法级别

所谓方法级别，即在每个测试方法(测试用例)执行前后都会自动调用的结构。

在这里插入图片描述

类级别

所谓类级别，即在每个类开始前和结束后，各执行一次(不管该类中有多少方法，都只执行一次)。

在这里插入图片描述

模块级别

所谓模块级别，即在每个代码文件执行前后都会自动调用的结构。

UnitTest 断言

断言:让程序代替人工自动地判断预期结果和实际结果是否相符。

断言的结果:

True————该测试用例通过。
False————代码抛出异常,该测试用例不通过。

为什么学习断言

提高测试效率。
实现自动化测试(让脚本在无人看守的情况下自动运行)。

断言的常用方法

注意:在测试类中使用断言方法时，必须使用self.断言方法这种形式。

在这里插入图片描述

如上图所示，重点掌握以下方法:

assertEqual(预期结果,实际结果)，函数作用:判断预期结果与实际结果是否相等，如果相等，则测试用例通过，如果不相等，则测试用例不通过，抛出异常。
assertIn(预期结果,实际结果)，函数作用:判断预期结果是否包含在实际结果当中，如果包含，则测试用例通过，如果不包含，则测试用例不通过，抛出异常。其中实际结果不一定是个容器，例如:("admin","aabbadmindd")——————前面这种情况，也叫包含。

参数化

参数化:在测试方法中,使用变量来代替具体的测试数据，然后使用传参的方法将数据传递给参数。

工作中的场景:

测试数据一般放在json文件当中。
使用代码读取json文件，获取我们想要的测试数据。
最终测试数据必须以下形式—>[(),(),()……]或者[[],[],[]……]

安装插件

unittest框架本身是不支持参数化的，要想支持参数化，需要安装插件。

安装命令:pip install parameterized

参数化的使用

在这里插入图片描述

如上图红框,要想在unittest框架中使用参数化，除了测试用例要有形参外,还要引入相关插件import parameterized,并且在参数化的测试用例上添加@parameterized.expand(测试数据的变量名)装饰器。

跳过

跳过:对于一些未完成或者不满足测试条件的测试方法和测试类，不想执行，可以选择跳过。

使用方法(通过装饰器来完成):

@unittest.skip('跳过的原因'),将该装饰器放在对应的方法或类上面,系统执行时可以直接跳过它们。
@unittest.skipIf(判断条件,'跳过的原因'),根据判断条件是否成立，来决定是否跳过，若判断条件成立，则跳过，反之则不跳过。

测试报告

Unit Test框架自带的TestRunner测试运行模块一次只能生成单个测试类的测试报告，要想生成多个测试类的综合(通过TestSuite打包)测试报告，则需要使用第三方的模块来生成第三方的测试报告。

生成第三方的测试报告

获取第三方的 测试运行模块 ，将其放在项目代码的目录当中。
导包 unittest以及第三方测试运行模块。
使用套件对象，加载对象去添加测试用例。
实例化 第三方的运行对象 并运行套件对象。

第三方测试运行模块的使用

我这里使用的是HTMLTestRunner.py文件和HTMLTestRunnerCN.py文件,两者区别在前者能够生成英文版的测试报告，后者能够生成中文版的测试报告。

首先引入第三方测试运行模块。
实例函数 HTMLTestRunner()共有四个参数，参数1:stream=? 必填，测试报告的文件对象(用open通过wb形式打开的)，参数2:verbosity=? 可选，报告的详细程度，默认1 简略，2 详细，参数3:title=? 可选,测试报告的标题，参数4:description=? 可选，描述信息，如python版本，pycharm版本。
通过.run(TestSuite对象)来运行测试用例。
中文测试报告模块的实例化函数为HTMLTestReporterCN(),其参数与 HTMLTestRunner()的参数类似,只是在末尾多了一个可选参数:tester=? 可选，记录测试人的信息。

第三方测试运行模块具体文件

文件名:HTMLTestRunner.py(生成英文测试报告)
