Feature/step-transformation #62

Closed spyoungtech closed 5 years ago

spyoungtech commented 5 years ago

Addresses #61

Also adds some other really exciting things and capabilities I wasn't sure would be possible.

Still need to write some more tests, work on Py2 compatibility (or maybe we'll drop support for Py2), but looks really promising so far.

@urosn74 -- feel free to checkout this branch and see if this meets your expectations. So far, I've only tested the environment variable transformer, but I believe this has the components you're looking for.

I've presented the feature as a fixture. So, to use it across all step definitions in the library, you can do the following

from behave.fixtures import use_fixture
from behave_webdriver.transformers import EnvironmentFormatTransformer
def before_all(context):
    use_fixture(EnvironmentFormatTransformer, context)

You can also use this on a per-scenario or per-feature basis using tags like so

Feature: Using a transformation fixture from feature file
  @fixture.transformer.EnvironmentFormatTransformer
  Scenario: transform step from environment variable
    Given the base url is "{ENV_BASE_URL}"
    When I open the site "/page.html"
    Then I expect that the url is "http://127.0.0.1:8000/page.html"

Then in your environment file

from behave_webdriver import use_fixture_tag

def before_tag(context, tag):
    use_fixture_tag(context, tag)

Then it will automagically find the transformer class and apply it when the tag is used.

So, if you set an environment variable ENV_BASE_URL and then run the feature file test

behave tests/features/transformation_fixture.feature

You should get an output something like

Feature: Using a transformation fixture from feature file # tests/features/transformation_fixture.feature:1

  @fixture.transformer.EnvironmentFormatTransformer
  Scenario: transform step from environment variable                # tests/features/transformation_fixture.feature:4
    Given the base url is "{ENV_BASE_URL}"                          # behave_webdriver/steps/actions.py:164
    When I open the site "/page.html"                               # behave_webdriver/steps/actions.py:157
    Then I expect that the url is "http://127.0.0.1:8000/page.html" # behave_webdriver/steps/expectations.py:149

Hi @spyoungtech. That was superfast :-)

I am a bit tight with my time, but will try to test this this evening.
