利用coverage统计Python代码覆盖率

coverage联合nosetests做单测覆盖率：

nosetests --with-coverage --cover-html

命令1 ：

coverage help

命令2：启动命令，后面参数为原程序启动参数 Python es_proxyapp.py 8999 coverage run es_proxyapp.py 8999 coverage run start.py args1 args2... 

命令3：显示覆盖率报告 coverage report coverage report -m coverage report -m my_program1.py  my_program2.py

命令4：生成HTML覆盖率报告 coverage html -d coverage_html
