递归单元测试发现 [英] Recursive unittest discover

问题描述

我有一个包含tests"目录的包，我在其中存储了我的单元测试.我的包裹看起来像:

<预><代码>.├── 执照├── 模型│ └── __init__.py├── README.md├──需求.txt├── tc.py├── 测试│ ├── db│ │ └── test_employee.py│ └── test_tc.py└── 待办事项.txt

从我的包目录中，我希望能够找到 tests/test_tc.py 和 tests/db/test_employee.py.我不想安装第三方库(nose 等)，也不想手动构建 TestSuite 来运行它.

当然有办法告诉 unittestdiscover 在找到测试后不要停止查找吗?python -m unittest discover -s tests 会找到 tests/test_tc.py 而 python -m unittest discover -s tests/db 会找到 tests/test_tc.py代码>tests/db/test_employee.py.没有办法同时找到吗?

解决方案

在做一些挖掘时，似乎只要更深的模块仍然可导入，它们就会通过 python -m unittest discover<被发现/代码>.那么，解决方案是简单地向每个目录添加一个 __init__.py 文件以将它们打包.

<预><代码>.├── 执照├── 模型│ └── __init__.py├── README.md├──需求.txt├── tc.py├── 测试│ ├── db│ │ ├── __init__.py # NEW│ │ └── test_employee.py│ ├── __init__.py # NEW│ └── test_tc.py└── 待办事项.txt

只要每个目录都有一个__init__.py，python -m unittestdiscover就可以导入相关的test_*模块.>

I have a package with a directory "tests" in which I'm storing my unit tests. My package looks like:

.
├── LICENSE
├── models
│   └── __init__.py
├── README.md
├── requirements.txt
├── tc.py
├── tests
│   ├── db
│   │   └── test_employee.py
│   └── test_tc.py
└── todo.txt

From my package directory, I want to be able to find both tests/test_tc.py and tests/db/test_employee.py. I'd prefer not to have to install a third-party library (nose or etc) or have to manually build a TestSuite to run this in.

Surely there's a way to tell unittest discover not to stop looking once it's found a test? python -m unittest discover -s tests will find tests/test_tc.py and python -m unittest discover -s tests/db will find tests/db/test_employee.py. Isn't there a way to find both?

解决方案

In doing a bit of digging, it seems that as long as deeper modules remain importable, they'll be discovered via python -m unittest discover. The solution, then, was simply to add a __init__.py file to each directory to make them packages.

.
├── LICENSE
├── models
│   └── __init__.py
├── README.md
├── requirements.txt
├── tc.py
├── tests
│   ├── db
│   │   ├── __init__.py       # NEW
│   │   └── test_employee.py
│   ├── __init__.py           # NEW
│   └── test_tc.py
└── todo.txt

So long as each directory has an __init__.py, python -m unittest discover can import the relevant test_* module.
