这篇文章主要为大家详细介绍了unittest+coverage单元测试代码覆盖操作的实例,具有一定的参考价值,感兴趣的小伙伴们可以参考一下

基于上一篇文章,这篇文章是关于使用coverage来实现代码覆盖的操作实例,源代码在上一篇已经给出相应链接。

本篇文章字用来实现代码覆盖的源代码,整个项目的测试框架如下:

就是在源代码的基础上加了一个CodeCover.py文件,执行该文件会在目录CoverageReport生成相应的覆盖报告。如下是CodeCover.py的源码:

#coding=utf8 
import os 
import time 
 
def findTestWithPath(): 
  current_dir=os.getcwd() 
  folderName=os.listdir(current_dir) 
  #print folderName 
  #获取到测试文件所在目录 
  TestSuit=[suite for suite in folderName if  not suite.find("TestSuit")] 
  #用来保存测试文件 
  testfile=[] 
  withPathFile=[] 
  for suite in TestSuit: 
      #获取测试目录下的所有测试文件 
      testfile=testfile+os.listdir(".\\"+suite) 
      for withPath in testfile: 
        withPath=current_dir+"\\"+suite+"\\"+withPath 
        withPathFile.append(withPath) 
  del testfile 
  #把testfile中的py文件挑选出来 
  withPathFile=[name for name in withPathFile if not "pyc" in name] 
  #print testfile 
  print withPathFile 
  return withPathFile 
 
def codeCoverage(): 
  now = time.strftime("%Y%m%d%H%M")  
  htmlReport=os.getcwd()+"\\"+"CoverageReport" 
  htmlCmd="coverage html -d " + htmlReport +"\\"+now 
  for pyfile in findTestWithPath():  
    runPyCmd="coverage run " + pyfile 
    if os.path.exists(htmlReport) :       
      os.system(runPyCmd) 
      os.system(htmlCmd) 
    else: 
      os.mkdir(htmlReport) 
      os.system(runPyCmd) 
      os.system(htmlCmd) 
       
 
if __name__=="__main__": 
  codeCoverage()
