Nose testing

For Unix like systems the nose will install by using following methods

Install nose using setuptools/distribute:

      easy_install nose

Or pip:

      pip install nose

Or, if you don’t have setuptools/distribute installed, use the download link at right to download the source package, and install it in the normal fashion:

     python setup.py install

After installation of the nose you can run tests for your projects by using the following commands  on terminal

     cd path/to/project       

     nosetests

The output like this

..........................................................................................................

   Ran 20 tests in 1.220s

   OK

For help with nosetests’ many command-line options, try:

   nosetests -h 

  -h, --help            show this help message and exit
  -V, --version         Output nose version and exit
  -p, --plugins         Output list of available plugins and exit. Combine
                        with higher verbosity for greater detail
  -v, --verbose         Be more verbose. [NOSE_VERBOSE]
  --verbosity=VERBOSITY
                        Set verbosity; --verbosity=2 is the same as -v
  -q, --quiet           Be less verbose
  -c FILES, --config=FILES
                        Load configuration from config file(s). May be
                        specified multiple times; in that case, all config
                        files will be loaded and combined
   etc

Python3

• nose supports python3. 
• Building from source on python3 requires distribute.
• If you don’t have distribute installed, python3 setup.py install will install .
