django - Pytest 不能与 Django 和 Docker 一起使用 - AssertionError : local ('/dev/console' ) is not a file

Question

我在 Docker 中运行一个 Django 应用程序，一切正常，但是当我尝试运行测试时，它失败了，错误非常模糊。
运行 docker-compose run djangoapp coverage run -m pytest 结果:

Creating djangoapp_run ... done                                                         ================================================= test session starts ==================================================

docker 组成:

version: '3'

services:
  djangoapp:
    build: .
    container_name: djangoapp
    ports:
      - '8000:80'
      - '1433:1433'
    volumes: 
      - ./djangoapp:/var/www/html/djangoapp
    environment:
      - PYTHONUNBUFFERED=0

Answer 1

pytest递归遍历，docker 中的默认工作目录是 / .将这些组合起来......设置直接正确工作!

...
    environment:
      - PYTHONUNBUFFERED=0
    working_dir: /var/www/html/djangoapp
