Python: behave integration in setuptools' setup.py

Question

I have written a small utility package for handling file permissions. The structure follows the Python package standards:

.
|-- __init__.py                     # All the code is here, for now
`-- tests
    |-- __init__.py
    |-- permission_mode.feature     # Feature files for behave
    |-- steps                       
    |   |-- __init__.py
    |   `-- steps.py                # Step files for behave
    `-- test_modtools.py            # Nose tests

Both nose and behave run the tests from the command line without issues:

Nose:

$ nosetests
.
----------------------------------------------------------------------
Ran 1 test in 0.002s

OK

Behave:

$ behave
Feature: Lots of cheese # permission_mode.feature:1

  Scenario: blah  # permission_mode.feature:2
    Given a       # steps/steps.py:1 0.000s
    Then b        # steps/steps.py:5 0.000s

1 feature passed, 0 failed, 0 skipped
1 scenario passed, 0 failed, 0 skipped
2 steps passed, 0 failed, 0 skipped, 0 undefined
Took 0m0.000s

My setup.py file contains the following test spec:

test_suite='nose.collector',
tests_require=['nose']

And therefore python setup.py test runs nose tests with the same output as nosetests.

How do I configure behave as the package's test tool, so that python setup.py test will run behave?

Look at "setup.py" from behave. It contains the usage of the colocated "setuptools_behave.py" test runner (and installs it).

RECIPE FOR USAGE:

# -- file:setup.py
from setuptools_behave import behave_test
...

setup(
    ...
    tests_require=["behave>=1.2.4"],
    cmdclass = {
        "behave_test": behave_test,
    },
    ...    
)

To verify it, execute "python setup.py --help-commands". It should contain a command "behave_test". Otherwise, run "python setup.py behave_test --help".

Thanks! I've added this to my setup.py, and had two problems: a. behave_test does not install the packages in tests_require, so I have to install behave manually. b. After installing behave, python setup.py behave_test gives can't open file 'behave': [Errno 2] No such file or directory. This happens both with and without a virtual environment.

And thanks again for the attention. It's always a pleasure to get an answer from the actual developer.

Look this commit Provide simple test runner to run behave tests from setup.py.

Maybe for next release?

Thanks, that's good news. I have downloaded the latest code from github, and there are still some bugs with virtual environments. I tried hacking it a bit and changing sys.executable in line 124 to os.path.dirname(sys.executable), but it didn't solve the problem. Will open a ticket. github.com/behave/behave/blob/…
