How do I run unit tests on my Python code in Buildout?

I have a Python project which is managed by zc.buildout.

My buildout.cfg file looks like this:

[buildout]
parts = python ipython
develop = .
eggs = redditsubscraper
versions = versions

[versions]

[python]
recipe = zc.recipe.egg
interpreter = python
eggs = ${buildout:eggs}

[ipython]
recipe = zc.recipe.egg:scripts
eggs = ${buildout:eggs}
    ipython
scripts = ipython

I'd like to add a bin/test script for running unit tests on my library.

How can I add this script? Is there a recipe that I need which will enable me to run bin/test and have my unit tests run?

Solution

I found a way to do it.

Add a new section to buildout.cfg:

[test]
recipe = pbp.recipe.noserunner
eggs = ${buildout:eggs}
    pbp.recipe.noserunner
script = test

Add that section to your buildout:parts:

[buildout]
parts = python ipython test
# ...

Run bin/buildout and you'll get a script called test in the bin/ folder. Run that script to run all tests in your project.
