前言:最近一直在其他博客论坛上写python的相关技术博客->https://blog.csdn.net/jackmengjin,计划还是在博客园上写一些关于安装、排错、爬坑等等一些零散的技术点,这样感觉好一点(轻微强迫症患者= =)。

 

操作:

1.什么是htmltestrunner?

在网上(包括在python官方文库)找不到htmltestrunner相关解释资料。其实htmltestrunner是一个第三方的unittest html报告库,关于unittest在python官方文库上很容易找到:,下面是截取的部分说明:

unittest 单元测试框架是受到 junit 的启发,与其他语言中的主流单元测试框架有着相似的风格。其支持测试自动化,配置共享和关机代码测试。支持将测试样例聚合到测试集中,并将测试与报告框架独立。

为了实现这些,unittest 通过面向对象的方式支持了一些重要的概念。

测试脚手架

test fixture 表示为了开展一项或多项测试所需要进行的准备工作,以及所有相关的清理操作。举个例子,这可能包含创建临时或代理的数据库、目录,再或者启动一个服务器进程。

测试用例

一个测试用例是一个独立的测试单元。它检查输入特定的数据时的响应。 unittest 提供一个基类: testcase ,用于新建测试用例。

测试套件

test suite 是一系列的测试用例,或测试套件,或两者皆有。它用于归档需要一起执行的测试。

测试运行器(test runner)

test runner 是一个用于执行和输出测试结果的组件。这个运行器可能使用图形接口、文本接口,或返回一个特定的值表示运行测试的结果。

unittest 模块提供了一系列创建和运行测试的工具。这一段落演示了这些工具的一小部分,但也足以满足大部分用户的需求。

这是一段简短的代码,来测试三种字符串方法:

import unittest

class teststringmethods(unittest.testcase):

    def test_upper(self):
        self.assertequal('foo'.upper(), 'foo')

    def test_isupper(self):
        self.asserttrue('foo'.isupper())
        self.assertfalse('foo'.isupper())

    def test_split(self):
        s = 'hello world'
        self.assertequal(s.split(), ['hello', 'world'])
        # check that s.split fails when the separator is not a string
        with self.assertraises(typeerror):
            s.split(2)

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

 

通过以上资料可以看到unittest能够输出txt格式的文本执行报告,但是文本报告太过简陋,是不是想要更加高大上的html报告?

但unittest自己可没有带html报告,我们只能求助于外部的库了——htmltestrunner.py。

2.下载htmltestrunner.py

为什么是下载htmltestrunner.py而不直接是htmltestrunner呢?

揭晓答案前我们先用常规手段下载htmltestrunner:

  • 通过pycharm下载htmltestrunner

python3.x安装HTMLTestRunner和使用

确保使用的是豆瓣源下载后,点击安装:

python3.x安装HTMLTestRunner和使用

果然报错...,为什么会报错呢?

python3.x安装HTMLTestRunner和使用

  • 通过pip下载htmltestrunner

这里我再尝试下使用pip下载:

python3.x安装HTMLTestRunner和使用

结果发现不管怎么尝试,都是不行:)

于是我查了下资料,得到了一个结论:原因其实就是htmltestrunner是python标准库的unittest模块的扩展,无法通过pip安装。

那么我们要怎么使用和下载htmltestrunner呢?

其实解决方法很简单,需要通过手动下载htmltestrunner.py文件,放在python目录lib文件夹下即可:

python3.x安装HTMLTestRunner和使用

由于当前python2.x绝大多数情况下不再使用,这里之将支持python3.x的htmltestrunner.py文件放上来:

"""
a testrunner for use with the python unit testing framework. it
generates a html report to show the result at a glance.

the simplest way to use this is to invoke its main method. e.g.

    import unittest
    import htmltestrunner

    ... define your tests ...

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


for more customization options, instantiates a htmltestrunner object.
htmltestrunner is a counterpart to unittest's texttestrunner. e.g.

    # output to a file
    fp = file('my_report.html', 'wb')
    runner = htmltestrunner.htmltestrunner(
                stream=fp,
                title='my unit test',
                description='this demonstrates the report output by htmltestrunner.'
                )

    # use an external stylesheet.
    # see the template_mixin class for more customizable options
    runner.stylesheet_tmpl = '<link rel="stylesheet" href="my_stylesheet.css" type="text/css">'

    # run the test
    runner.run(my_test_suite)

3.如何使用htmltestrunner?

首先先确定可以使用htmltestrunner:

python3.x安装HTMLTestRunner和使用

没报错?那继续,打开pycharm,把下面这块代码复制粘贴进去:

import unittest
import htmltestrunner
class testadd(unittest.testcase):
    def setup(self):
        pass
    def test_add1(self):
        self.assertequal(2 + 3 + 10,15)
    def test_add2(self):
        self.assertequal(10 + 150,160)
    def test_add3(self):
        #一处出错,查看测试结果
        self.assertequal(2 * 5 * 7, 40)
    def teardown(self):
        pass
def suite():
    suitetest=unittest.testsuite()
    suitetest.addtest(testadd("test_add1"))
    suitetest.addtest(testadd("test_add2"))
    suitetest.addtest(testadd("test_add3"))
    return suitetest
if __name__=="__main__":
   # 存放路径在e盘目录下
   filepath='e:\\pyresult.html'
   fp=open(filepath,'wb')
   #定义测试报告的标题与描述
   runner = htmltestrunner.htmltestrunner(stream=fp,title=u'我是风起怨江南的测试报告标题',description=u'我是风起怨江南的测试报告描述')
   runner.run(suite())
   fp.close()

运行,查看结果:

g:\helloworld\python\pycharm\jackmeng\scripts\python.exe g:/helloworld/python/pycharm/jackmeng/htmltestrunner_demo.py
<_io.textiowrapper name='<stderr>' mode='w' encoding='utf-8'> 
time elapsed=0:00:00.000948

python3.x安装HTMLTestRunner和使用

那么e盘下到底有没有生成html测试报告文件呢?

答案自然是生成了:

python3.x安装HTMLTestRunner和使用

点开看看测试报告:

测试结果自然不言而喻:完美!
