我正在对分配给我的项目进行测试。一切都是通过调用 tox 来触发的。默认测试使用nose运行，它添加了一个覆盖率报告，这是tox调用的命令：
django-admin test -s
和设置文件有这个鼻子的配置：
NOSE_ARGS = [
'--with-coverage',
'--cover-erase',
'--cover-package=app_name',
'--cover-inclusive'
]
这是使用 tox 流鼻涕时显示的报告：
Name Stmts Miss Cover

现在，如您所见，鼻子报告忽略了某些文件，但覆盖率显示了某些文件，例如app_name/services/account_service.py. 由于该文件包含功能代码，因此应在报告中显示。
有趣的是，据我所知，这两个库：nose 和 coverage 都从同一个报告文件生成它们的报告.coverage
我想这是一个默认的鼻子行为。我对鼻子不是很熟悉，所以也许有人可以告诉我为什么会发生这种行为差异。
