Question

我正在使用http://nedbatchelder.com/code/coverage/中的coverage.py获取我的django单元测试的覆盖率数据，但我似乎无法弄清楚如何在django调试服务器上运行覆盖。我想使用：

运行django服务器

coverage -x manage.py runserver 0.0.0.0:8080

当停止此服务器时，我应该获取覆盖数据，我可以使用它生成覆盖率报告。但是在使用CTRL-c关闭服务器时，我得到了

^ CCoverage.py警告：未收集任何数据。

如果无法使用此coverage.py脚本，我准备使用任何其他工具。

更新：

使用--noreload它似乎确实有效但在生成html覆盖率报告时我得到以下堆栈跟踪：

  File "/usr/local/bin/coverage", line 8, in <module>

嗯，不知道该怎么做。当我创建一个全新的Django项目时，我得到一些覆盖率测量：

$ 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%

什么操作系统，Django和覆盖版本等？您项目中还有其他不寻常之处吗？

单独测量runserver可能不是您想要的，您可能只测量监视文件更改的代码并重新启动服务器。具有覆盖支持的Django测试运行器可以更好地满足您的需求。

更新：

提供--noreload开关可以覆盖所有代码。

使用django调试服务器进行代码覆盖
