django調試服務器的代碼覆蓋率

Question

我使用的coverage.py獲取我的django unittests的覆蓋率數據，但我似乎無法弄清楚如何在django調試服務器上運行覆蓋率。我想用運行Django的服務器：

coverage -x manage.py runserver 0.0.0.0:8080 

，並停止該服務器時，我應該使用覆蓋數據，我可以生成覆蓋報告獲得。但是在用CTRL-c關閉服務器時，我得到了

^CCoverage.py警告：沒有收集到數據。

如果無法使用此coverage.py腳本，則可以使用任何其他工具。

UPDATE：

隨着--noreload它似乎工作，但生成HTML覆蓋率報告時，我得到了下面的堆棧跟蹤：

traceback (most recent call last): 
    File "/usr/local/bin/coverage", line 8, in <module> 
    load_entry_point('coverage==3.5.1', 'console_scripts', 'coverage')()

    status = CoverageScript().command_line(argv) 
    File "/usr/local/lib/python2.6/dist-packages/coverage/cmdline.py", line 549, in command_line

    write_encoded(fname, html, 'ascii', 'xmlcharrefreplace') 
    File "/usr/local/lib/python2.6/dist-packages/coverage/backward.py", line 137, in write_encoded 
    f.write(text.decode('utf8')) 
    File "/usr/lib/python2.6/encodings/utf_8.py", line 16, in decode 
    return codecs.utf_8_decode(input, errors, True) 
UnicodeDecodeError: 'utf8' codec can't decode byte 0xdf in position 59130: invalid continuation byte

嗯，不知道該做出什麼。當我創建一個全新的Django項目，我得到一些覆蓋測量：

$ django-admin.py startproject mysite 
$ cd mysite 
$ coverage run manage.py runserver 
Validating models... 

0 errors found 
Django version 1.3, using settings 'mysite.settings' 
Development server is running at http://127.0.0.1:8000/ 
Quit the server with CTRL-BREAK. 
^C 
$ coverage report 
Name  Stmts Miss Cover 
------------------------------ 
__init__  0  0 100% 
manage  11  4 64% 
settings  24  0 100% 
------------------------------ 
TOTAL   35  4 89% 

什麼操作系統，Django和覆蓋版本，等？你的項目中還有什麼不尋常的東西？

單獨測量runserver可能不是您想要的，您只能測量監視文件更改並重新啓動服務器的代碼。支持覆蓋支持的Django測試運行人員可能更適合您的需求。

更新：

提供--noreload開關使覆蓋測量您的所有代碼。
