pytestboilerplate 0.0.3

pytest-boilerplate
pytest is a mature testing framework for Python that is developed
by a thriving and ever-growing community of volunteers. It uses plain assert
statements and regular Python comparisons. At the core of the pytest test
framework is a powerful hook-based plugin system.
pytest-boilerplate is a pytest plugin that comes with a boilerplate fixture
which is a wrapper for the devxhub_python API for generating
projects. It helps you verify that your template is working as expected and
takes care of cleaning up after running the tests. 🍪
Installation
pytest-boilerplate is available for download from PyPI via pip:
pip install pytest-boilerplate

This will automatically install pytest and
devxhub_python.
Usage
Generate a new project
The boilerplate.bake() method generates a new project from your template
based on the default values specified in devxhub_python.json:
def test_bake_project(boilerplate):
result = boilerplate.bake(extra_context={"repo_name": "helloworld"})

assert result.exit_code == 0
assert result.exception is None

assert result.project_path.name == "helloworld"
assert result.project_path.is_dir()

# The `project` attribute is deprecated
assert result.project.basename == "helloworld"
assert result.project.isdir()

Please note that the project attribute of the returned Result class is
deprecated and will be removed in a future release, please use project_path
instead.
The boilerplate.bake() method also accepts the extra_context keyword
argument that will be passed to devxhub_python. The given dictionary will
override the default values of the template context, effectively allowing you
to test arbitrary user input data.
For more information on injecting extra context, please check out the
devxhub_python documentation.
Specify the template directory
By default boilerplate.bake() looks for a devxhub_python template in the
current directory. This can be overridden on the command line by passing a
--template parameter to pytest:
pytest --template TEMPLATE

You can customize the devxhub_python template directory from a test by passing
in the optional template paramter:
@pytest.fixture
def custom_template(tmpdir):
template = tmpdir.ensure("devxhub_python-template", dir=True)
template.join("devxhub_python.json").write('{"repo_name": "example-project"}')

repo_dir = template.ensure("{{devxhub_python.repo_name}}", dir=True)
repo_dir.join("README.rst").write("{{devxhub_python.repo_name}}")

return template

def test_bake_custom_project(boilerplate, custom_template):
"""Test for 'devxhub_python-template'."""
result = boilerplate.bake(template=str(custom_template))

assert result.exit_code == 0
assert result.exception is None

assert result.project_path.name == "example-project"
assert result.project_path.is_dir()

Keep output directories for debugging
By default boilerplate removes baked projects.
However, you can pass the keep-baked-projects flag if you'd like to keep
them (it won't clutter as pytest only keeps the
three newest temporary directories):
pytest --keep-baked-projects
