coverage聯合nosetests做單測覆寫率：

nosetests --with-coverage --cover-html

指令1 ：

coverage help

指令2：啟動指令，後面參數為原程式啟動參數 Python es_proxyapp.py 8999 coverage run es_proxyapp.py 8999 coverage run start.py args1 args2... 

指令3：顯示覆寫率報告 coverage report coverage report -m coverage report -m my_program1.py  my_program2.py

指令4：生成HTML覆寫率報告 coverage html -d coverage_html
