Traceback occurs when step sentence is used with cardinality and standard types

I am using Python 2.7.10, MacOS Sierra version 10.12.4 and Radish-BDD version 0.6.2

>>> radish.__VERSION__
'0.6.2'
>>>

With the feature file of:

Feature: A test feature for issues with cardinality used in sentence parameters
  A feature description here

  Scenario: Fruit Consumption 1
    Given I have a apple
    When I eat the apple,pear,banana
    Then I get lots of fiber

steps.py contents:

import re

from radish import given, when, then


@given(r'I have a {fruit:S}')
def my_step(step, fruit):
    pass

@when(r'I {method:S} the {fruits:S+}')
def my_step(step, method, fruits):
    pass

@then(r'I get lots of {what:S}')
def my_step(step, what):
    pass

Then:

$ radish -b tests/stuff/ tests/stuff/features/ --early-exit
Error: 'S'

NOTE: The test runs without issues if the cardinality, e.g. ‘+’, is not specified in the step sentence decorator. Also, tried the cardinality with ‘d’ as well with similar message.

So,

Given the same feature file as above and the following changes to the steps.py:

...
@when(r'I {method:S} the {fruits:S}')
def my_step(step, method, fruits):
    pass
...

Then:

$ radish -b tests/stuff/ tests/stuff/features/ --early-exit
Feature: A test feature for issues with cardinality used in sentence parameters  # tests/stuff/features/stuff.feature
    A feature description here

@timofurrer I will see if I can make some time today to investigate.

I’m closing this - see the previously marked issue in parse_type.
