python-watching-testrunner

python-watching-testrunner provides automatic test execution on file changes.

Why

Because unit testing is even more fun

* when you don't have to switch out of your editor to get feedback from unit tests.
* the shorter the feedback period is till you get feedback from your tests.

I've seen the usefullness toying with rubys autotest command, so I pestered Felix to build something like this, and after using it for about a two years, I finally got around to packaging it.

In addition to that it's brain dead simple, has no dependencies and is _really_ small.

Usage

        % watching_testrunner --help
        Usage: watching_testrunner [options] command [arguments...]

        Options:
          -h, --help            show this help message and exit
          -b BASEPATH, --basepath=BASEPATH
                                base path to watch for changes
          -p WATCH_WILDCARD, --pattern=WATCH_WILDCARD
                                glob-style pattern for file names to watch

Examples

   watching_testrunner nosetessts $NOSETESTS_ARGUMENTS

This will run nosetests whenever any python file below the current directory changes

     watching_testrunner --basepath foo/bar --pattern="*" nosetessts $NOSETESTS_ARGUMENTS

This will run nosetests whenever any file below ./foo/bar changes.

  watching_testrunner --basepath path/to/js_tests --pattern="*.js" jasmine --console

 This will run jasmine --console whenever any js file below ./path/to/js_tests changes (i.e. you can use the watching testrunner to get auto test execution using any tool for any language).
