Running the Tests

Panko includes an extensive set of automated unit tests which are run through tox.

1. Install tox:

   $ sudo pip install tox
   

2. On Ubuntu install mongodb and libmysqlclient-dev packages:

   $ sudo apt-get install mongodb
   $ sudo apt-get install libmysqlclient-dev
   

   For Fedora20 there is no libmysqlclient-dev package, so you’ll need to install mariadb-devel.x86-64 (or mariadb-devel.i386) instead:

   $ sudo yum install mongodb
   $ sudo yum install mariadb-devel.x86_64
   

3. Install the test dependencies:

   $ sudo pip install -r /opt/stack/panko/test-requirements.txt
   

4. Run the unit and code-style tests:

   $ cd /opt/stack/panko
   $ tox -e py27,pep8
   

   As tox is a wrapper around testr, it also accepts the same flags as testr. See the testr documentation for details about these additional flags.

Use a double hyphen to pass options to testr. For example, to run only tests under tests/api/v2:

$ tox -e py27 -- api.v2

To debug tests (ie. break into pdb debugger), you can use ‘’debug’’ tox environment. Here’s an example, passing the name of a test since you’ll normally only want to run the test that hits your breakpoint:

$ tox -e debug panko.tests.test_bin

For reference, the debug tox environment implements the instructions here: https://wiki.openstack.org/wiki/Testr#Debugging_.28pdb.29_Tests

5. There is a growing suite of tests which use a tool called gabbi to test and validate the behavior of the Panko API. These tests are run when using the usual py27 tox target but if desired they can be run by themselves:

   $ tox -e gabbi
   

   The YAML files used to drive the gabbi tests can be found in panko/tests/gabbi/gabbits. If you are adding to or adjusting the API you should consider adding tests here.
