behave is behaviour-driven development, Python style
Project description
Behavior-driven development (or BDD) is an agile software development technique that encourages collaboration between developers, QA and non-technical or business participants in a software project.
behave uses tests written in a natural language style, backed up by Python code.
First, install *behave*.
Now make a directory called “example”. In that directory create a file called “example.feature” containing:
Feature: showing off behave Scenario: run a simple test Given we have behave installed when we implement a test then behave will test it for us!
Make a new directory called “example/steps”. In that directory create a file called “example.py” containing:
from behave import * @given('we have behave installed') def step(context): pass @when('we implement a test') def step(context): assert True is not False @then('behave will test it for us!') def step(context): assert context.failed is False
Run behave:
% behave Feature: showin off behave # example/example.feature:1 Scenario: run a simple test # example/example.feature:3 Given we have behave installed # example/steps/example.py:3 When we implement a test # example/steps/example.py:7 Then behave will test it for us! # example/steps/example.py:11 1 feature passed, 0 failed, 0 skipped 1 scenario passed, 0 failed, 0 skipped 3 steps passed, 0 failed, 0 skipped, 0 undefined
Now, continue reading to learn how to the most of behave. To get started, we recommend the tutorial and then the feature testing language and api references.
