A plugin for nose2 implementing behavior-driven testing.
Project description
A plugin for running behavior-driven tests using gherkin inside nose2.
Usage
To enable planterbox for your project, you’ll want to add the following lines (or similar) to your unittest.cfg:
[unittest]
plugins = planterbox
[planterbox]
always-on = Trueplanterbox is compatible with nose2.plugins.mp.
Writing Tests
planterbox tests exist inside a python package which provides a context for their execution. You should write your tests in .feature files in the package directory. .feature files have access to all steps defined in or imported into their package’s __init__.py. For example, with the directory structure:
planterbox/
tests/
test_feature/
__init__.py
basic.feature
If __init__.py contains:
from planterbox import step
@step(r'I add (\d+) and (\d+)')
def add(test, a, b):
a = int(a)
b = int(b)
test.result = a + b
@step(r'the result should be (\d+)')
def check_result(test, value):
value = int(value)
test.assertEqual(test.result, value)basic.feature could contain:
Feature: Basic Tests
I want to exercise generation of a simple test from a feature.
Scenario: I need to verify basic arithmetic.
Given I add 1 and 1
Then the result should be 2We could then run this test either by running all of the tests in the suite with nose2 or run it specifically with nose2 planterbox.tests.test_feature:basic.feature. We could even run the first scenario specifically with nose2 planterbox.tests.test_feature:basic.feature:0.
