为什么PyTest覆盖率报告中缺少我项目的大多数Django文件? [英] Why are most of my project's Django files missing from the PyTest Coverage report?
问题描述
我正在使用tox运行pytest-cov和pytest-django.我有一个非常简单的tox.ini文件，有限的omit文件.问题是，当我使用tox -e unit运行pytest时，得到的覆盖率报告有限:
I'm running pytest-cov and pytest-django using tox. I have a very simple tox.ini file with limited omit files. The problem is when I run pytest using tox -e unit, I get a limited Coverage report:

我在components下的所有Django应用程序都有许多应在报告中涵盖的文件，包括apps，serializers，signals，urls和views(标准Django结构). .有人知道我想念什么吗?我在tox.ini中拥有的所有内容似乎都完全按照我在pytest，pytest-django，pytest-cov和coverage的各种文档中阅读的内容进行，但是我必须缺少一些重要的内容！
All of my Django apps under components have many files that should be covered in the report, including apps, serializers, signals, urls, and views (the standard Django structure). Anyone have any idea what I'm missing? Everything I've got in the tox.ini seems to follow pretty much exactly what I've read in the various documentation for pytest, pytest-django, pytest-cov, and coverage, but I must be missing something important!
tox.ini
[tox]
; The only reason we'd want to `sdist` is if we distributed this as a Python package in PyPI, so let's skip it:
skipsdist = True
envlist =

lint

[testenv]

passenv = *

推荐答案
答案似乎很简单，也很明显，但是令人惊讶的是，很难找到答案. coverage将仅报告实际运行的代码.因此，如果您的测试未调用任何代码，并且在正常加载应用程序期间未运行该代码，则coverage将不会显示该代码的报告.不运行的代码不会导致错误:)
The answer seems quite trivial and obvious, but amazingly, it was quite difficult to come by. coverage will only report on code that is actually run. So if your tests don't call a bit of code and it doesn't get run during normal loading of the application, coverage will not show a report for that code. Code that doesn't run does not cause bugs :)
