Feature: Execute Steps within a Step Function (Nested Steps)
As a tester
I want to reuse existing steps and call several ones within another step
So that I can comply with the the DRY principle.
Scenario: Execute a number of simple steps (GOOD CASE)
Given a new working directory
And a file named "features/steps/steps.py" with:
"""
from behave import given, when, then
@given(u'I go to the supermarket')
def step_given_I_go_to_the_supermarket(context):
context.shopping_cart = {}
@when(u'I buy {amount:n} {item:w}')
def step_when_I_buy(context, amount, item):
assert amount >= 0
if not item in context.shopping_cart:
context.shopping_cart[item] = 0
context.shopping_cart[item] += amount
# -- HERE: Is the interesting functionality.
@when(u'I buy the usual things')
def step_when_I_buy_the_usual_things(context):
context.execute_steps(u'''
When I buy 2 apples
And I buy 3 bananas
''')
@then(u'I have {amount:n} {item:w}')
def step_then_I_have(context, amount, item):
actual = context.shopping_cart.get(item, 0)
assert amount == actual
"""
And a file named "features/use_nested_steps.feature" with:
"""
Feature:
Scenario:
Given I go to the supermarket
When I buy the usual things
Then I have 2 apples
And I have 3 bananas
"""
When I run "behave -f plain features/use_nested_steps.feature"
Then it should pass with:
"""
1 feature passed, 0 failed, 0 skipped
1 scenario passed, 0 failed, 0 skipped
4 steps passed, 0 failed, 0 skipped, 0 undefined
