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，这工作得很好。但在其他情况下，当我输入“nosetests”时，不会运行任何测试。如果我单独调用这些测试，它们就会运行，但我需要它们全部自动运行。这是不起作用的目录之一：

/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 /extwebserver 或其他子目录或父目录本身的测试。

编辑 这是输出：

Answer 1

来自 Daniel Arbuckle 的 Python 测试：初学者指南：

Nose 在名称以 test 和 Test 开头，或包含 '_'、的目录和模块中查找测试'.' 或 '-' 后跟 test 或 Test。这是默认设置，但实际上并不是全部。

鼻子单元测试框架的扩展介绍表明您可以看到通过运行以下命令，可以查看鼻子测试发现算法的详细输出：

nosetests -vv --collect-only

当我在目录上运行上述命令时，我注意到鼻子会跳过可执行文件。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 `manosetests）：

nosetests --exe

Answer 2

您可以在命令行中使用--exe来强制nose将可执行文件视为有效测试。如果您厌倦了每次都编写 --exe ，您可以添加以下行：

exe=真

在您的主目录中的 .noserc（对于 unix/linux）或nose.cfg（对于 windows）文件中。
