单元测试Unittest框架，一篇文章解释清楚（下）
简介单元测试Unittest框架，一篇文章解释清楚（下）
之前的文章我们讲了单元测试框架及用法，在测试用例中添加Fixture，今天我们来讲如何生成测试报告。
输出测试报告
UnitTest框架执行测试用例完成后会在控制台输出如上的结果，但实际测试过程中，我们需要输出测试报告，这个时候我们需要使用第三方模块。
1 HTMLTestRunner
HTMLTestRunner模块可以直接生成html格式的报告。
下载地址：http://tungwaiyip.info/software/HTMLTestRunner.html
下载后需要修改:
-
94行引入的名称要改，从 import StringIO修改成 import io
-
539行 self.outputBuffer = StringIO.StringIO()修改成self.outputBuffer=io.StringIO()
-
631行 print >>sys.stderr, ' Time Elapsed: %s' % (self.stopTime-self.startTime)修改成print (sys.stderr, ' Time Elapsed: %s' %(self.stopTime-self.startTime))
-
642行，if not rmap.has_key(cls): 修改成 if not cls in rmap:
-
766行的uo = o.decode('latin-1')，修改成 uo=o
-
772行，把 ue = e.decode('latin-1') 直接改成 ue = e
存放路径：将修改完成的模块存放在Python路径下Lib目录里即可。
run.py示例代码如下：
# -*- coding:utf-8 -*-
# @author: 给你一页白纸
import time
import unittest
import HTMLTestRunner
# 获取当前时间并指定时间格式，用于测试报告命名
now = time.strftime("%Y-%m-%d_%H_%M_%S")
# 测试报告存储路径
report_dir = './report/'
# 创建报告文件，并以写的形式打开文件，用于写入报告内容
fp = open(report_dir + now + "_report.html", 'wb')
# 初始化一个HTMLTestRunner实例对象，用来生成报告
runner = HTMLTestRunner.HTMLTestRunner(stream=fp,
title="App自动化测试报告",
description="测试用例情况")
# 定义测试用例路径
test_dir='./testcase'
# 加载测试用例
suite = unittest.defaultTestLoader.discover(test_dir, pattern='test_*.py')
# 执行测试用例
runner.run(suite)
fp.close()运行run.py，会看到report中生成了html文件，即为测试报告：
浏览器打开该文件，内容如下：
从报告内容中看出HTMLTestRunner.HTMLTestRunner()方法中参数所对应的内容，可以根据项目的实际需要指定参数内容。
2 美化版测试报告
在HTMLTestRunner基础上美化过的报告：
"""
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 BSTestRunner
... define your tests ...
if __name__ == '__main__':
BSTestRunner.main()
For more customization options, instantiates a BSTestRunner object.
BSTestRunner is a counterpart to unittest's TextTestRunner. E.g.
# output to a file
fp = file('my_report.html', 'wb')
runner = BSTestRunner.BSTestRunner(
stream=fp,
title='My unit test',
description='This demonstrates the report output by BSTestRunner.'
)
# 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)
