Eucalyptus - BDD plugin for Pytest

A nice fork of Aloe. Migrated from Nose to Pytest.

pytest-eucalyptus has been built to feature the best of both worlds:

Aloe which implements great infrastructure and uses the original Gherkin parser.
pytest-bdd does not require a separate runner and benefits from the power and flexibility of Pytest.

Quick Start

Create new module and add empty __init__.py.
Install Pytest and Eucalyptus:
```
pip install pytest pytest-eucalyptus
```
Let's assume we are testing the following implementation of calculator.py:
```
    def add(*numbers):
        return sum(numbers)
```

Write your first feature tests/calculator.feature:

    Feature: Add up numbers

    As a mathematically challenged user
    I want to add numbers
    So that I know the total

    Scenario: Add two numbers
        Given I have entered 50 into the calculator
        And I have entered 30 into the calculator
        When I press add
        Then the result should be 80 on the screen

Add the definitions in tests/conftest.py:

    from calculator import add
    from pytest_eucalyptus import before, step, world


    @before.each_example
    def clear(*args):
        """Reset the calculator state before each scenario."""
        world.numbers = []
        world.result = 0


    @step(r'I have entered (\d+) into the calculator')
    def enter_number(self, number):
        world.numbers.append(float(number))


    @step(r'I press add')
    def press_add(self):
        world.result = add(*world.numbers)


    @step(r'The result should be (\d+) on the screen')
    def assert_result(self, result):
        assert world.result == float(result)

Run the code
