python - 使用 Nose 运行目录中的所有测试

Question

我需要能够通过在 Linux shell 中键入一行来运行当前目录中的所有测试。在某些目录中，这可以正常工作。但在其他情况下，当我输入“nosetests”时，不会运行任何测试。如果我单独调用它们，测试将运行，但我需要它们全部自动运行。以下是其中一个不起作用的目录:

/extwebserver
    __init__.py
    test_Detection.py
    test_Filesystem.py 
    test_Hardware.py
    ...

当我在父目录中运行“nosetests”时，某个子目录中的所有测试都会运行，但不会运行来自/extwebserver 或其他子目录或父目录本身的测试。

编辑 这是输出:

来自 Python Testing: Beginner's Guide丹尼尔·阿巴克尔:

Nose looks for tests in directories and modules whose names start with test and Test, or contain a '_', '.', or '-' followed by test or Test. That's the default, but it's not actually the whole story.

An Extended Introduction to the nose Unit Testing Framework表明您可以通过运行以下命令查看 Nose 的测试发现算法的详细输出:

nosetests -vv --collect-only

当我在一个目录上运行上述代码时，我注意到 Nose 跳过了可执行文件。如果这是您的问题，您需要将文件模式更改为不可执行。在 Mac OS X 或 Linux 上，这可以通过以下方式完成:

chmod 644 file.py

或类似的。

如果您知道您的模块/文件是导入安全的，那么您可以使用 --exe 选项运行 Nose 以“在可执行的 Python 模块中查找测试”(来自 `man Nose 测试):

nosetests --exe
