I have a feature file as blow. How could I import .csv file to replace Table in Examples?

Scenario Outline: Blenders
   Given I put <thing> in a blender,
    when I switch the blender on
    then it should transform into <other thing>

 Examples: Amphibians
   | thing         | other thing |
   | Red Tree Frog | mush        |

 Examples: Consumer Electronics
   | thing         | other thing |
   | iPhone        | toxic waste |
   | Galaxy Nexus  | toxic waste |

Table importing is not supported yet, as described here.

But according to the jenisys response in the same post, it will be available soon.

Table importing is not supported yet, but you can create helper method.

The x.feature file:

Feature: csv file

@dynamic
Scenario Outline: Load data from csv
  Then just print <username> <email> <password>
    Examples: Dynamic
      | username | email |  password |
      |    .     |   .   |      .    |

Step file (steps/step_file.py):

from behave import step


@step('just print {username} {email} {password}')
def step_impl(context, username, email, password):
    print(username, email, password)

The environment.py file:

from behave.model import ScenarioOutline
import copy
import csv


def before_feature(context, feature):
    features = (scenario for scenario in feature.scenarios if type(scenario) == ScenarioOutline and 'dynamic' in scenario.tags)
    for scenario in features:
        for example in scenario.examples: 
            orig = copy.deepcopy(example.table.rows[0])
            example.table.rows = []
            with open('test.json') as csv_file:
                csv_reader = csv.reader(csv_file, delimiter=',')
                for row in csv_reader:
                    n = copy.deepcopy(orig)
                    n.cells = ['{}'.format(row[0]), '{}'.format(row[1]), '{}'.format(row[2])]
                    example.table.rows.append(n)

the test.json file:

andrew,testemail1@example.com,1235aaa
mike,testemail1@example.com,1234bbb

The result is:

behave -i tutorial.feature
Feature: csv file # features/tutorial.feature:1

  @dynamic
  Scenario Outline: Load data from csv -- @1.1 Dynamic     # features/tutorial.feature:8
    Then just print andrew  testemail1@example.com 1235aaa # features/steps/step_test.py:4 0.000s

  @dynamic
  Scenario Outline: Load data from csv -- @1.2 Dynamic    # features/tutorial.feature:8
    Then just print marina testemail1@example.com 1234bbb # features/steps/step_test.py:4 0.000s

1 feature passed, 0 failed, 0 skipped
2 scenarios passed, 0 failed, 0 skipped
2 steps passed, 0 failed, 0 skipped, 0 undefined
Took 0m0.000s
