Feature: Issue #81: Allow defining steps in a separate library
. The current design forces steps.py to be in a particular folder.
. This does not allow to reuse a common library of BDD steps across
. multiple software projects in a company.
. It would be great if one could define a separate lib with common steps
. (e.g. steps4mycompany.py)
Background: Test Setup
Given a new working directory
And an empty file named "step_library42/__init__.py"
And a file named "step_library42/alice_steps.py" with:
"""
# -- ALICE-STEPS: Anonymous step names.
from behave import given, when, then
@given(u'I use the step library "{library}"')
def step(context, library):
pass
@when(u'I use steps from this step library')

pass
@then(u'these steps are executed')

pass

Then it should pass with:
"""

3 steps passed, 0 failed, 0 skipped, 0 undefined

And the command output should contain:
