django - 为什么鼻子会忽略覆盖率报告中的某些文件？

Question

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

但是，如果在它之后我运行coverage report它会显示：

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。
