Run all Tests in Directory Using Nose

I need to be able to run all tests in the current directory by typing one line in the Linux shell. In some directories, this works fine. But in others, when I type "nosetests" no tests are run. The tests will run if I call for them individually but I need them to all run automatically. Here is one of the directories that won't work:

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

When I run "nosetests" in the parent directory, all tests in a certain subdirectory are run but no tests from /extwebserver or other subdirectories or the parent directory itself are run.

EDIT Here's the output:

From Python Testing: Beginner's Guide by Daniel Arbuckle:

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 shows that you can see a verbose output from nose's test discovery algorithm by running:

nosetests -vv --collect-only

When I ran the above on a directory, I noticed that Nose skips executable files. If that's your problem, you'll need to change the file mode to non-executable. On Mac OS X or Linux, this can be accomplished with:

chmod 644 file.py

or similar.

If you know that your modules/files are import-safe, then you can run Nose with the --exe option to "look for tests in python modules that are executable" (from `man nosetests):

nosetests --exe

You can use --exe in the command line to force nose to consider executables files as valid tests. If you get tired of writting --exe everytime, you can put the line:
