Python Unit Test - Test Report: HTMLTestRunner -1

Posted 2021-07-21 Rolei_zl

htmlTestRunner 

1）http://tungwaiyip.info/software/HTMLTestRunner.html -- 网站提供的版本支持python2.7

2）HTMLTestRunner is an extension to the Python standard library's unittest module. It generates easy to use HTML test reports. 
     HTMLTestRunner扩展了python标准的单元测试库，方便生成HTML格式的测试报告。

3）HTMLTestRunner python2 转 python3

>> 调用HTMLTestReport时
    fp = file('my_report.html', 'wb') ->     fp = file('my_report.html', 'w')

5）使用HTMLTestRunner

import unittest
import os
import HTMLTestRunner

def pyjiou(n):
    if(n%2 == 0):
        print("ou shu")
        return "ou shu"
    else:
        print("ji shu")
        return "ji shu" 

def py10(n):
    if(n < 10):
        print("less 10")
        return "less 10"
    else:
        print("big 10")
        return "big 10"
