Problem
|
||
|
|
-------
|
||
|
|
|
||
|
|
As a user I have functional tests that I would like to run against various
|
||
|
|
scenarios.
|
||
|
|
|
||
|
|
In this particular example we want to generate a new project based on a
|
||
|
|
cookiecutter template. We want to test default values but also data that
|
||
|
|
emulates user input.
|
||
|
|
|
||
|
|
- use default values
|
||
|
|
- emulate user input
|
||
|
|
- specify 'author'
|
||
|
|
- specify 'project_slug'
|
||
|
|
- specify 'author' and 'project_slug'
|
||
|
|
|
||
|
|
This is how a functional test could look like:
|
||
|
|
|
||
|
|
.. code-block:: python
|
||
|
|
|
||
|
|
import pytest
|
||
|
|
|
||
|
|
@pytest.fixture
|
||
|
|
def default_context():
|
||
|
|
return {'extra_context': {}}
|
||
|
|
|
||
|
|
|
||
|
|
@pytest.fixture(params=[
|
||
|
|
{'author': 'alice'},
|
||
|
|
{'project_slug': 'helloworld'},
|
||
|
|
{'author': 'bob', 'project_slug': 'foobar'},
|
||
|
|
])
|
||
|
|
def extra_context(request):
|
||
|
|
return {'extra_context': request.param}
|
||
|
|
|
||
|
|
|
||
|
|
@pytest.fixture(params=['default', 'extra'])
|
||
|
|
def context(request):
|
||
|
|
if request.param == 'default':
|
||
|
|
return request.getfuncargvalue('default_context')
|
||
|
|
else:
|
||
|
|
return request.getfuncargvalue('extra_context')
|
||
|
|
|
||
|
|
|
||
|
|
def test_generate_project(cookies, context):
|
||
|
|
"""Call the cookiecutter API to generate a new project from a
|
||
|
|
template.
|
||
|
|
"""
|
||
|
|
result = cookies.bake(extra_context=context)
|
||
|
|
|
||
|
|
assert result.exit_code == 0
|
||
|
|
assert result.exception is None
|
||
|
|
assert result.project.isdir()
|
||
|
|
