Using sst in Lettuce

Asked by Le Chi Thu

When I use use sst actions in the Lettuce steps, the browser object is not initialized. Which is the best way to extent sst to support Lettuce ? http://lettuce.it/index.html

See the example below:

blog.feature:

Feature: Personal Blog

  Scenario: Visit the main page
   Given I am at http://localhost:4000
   Then I should see the title Rodney's Corner

steps.py:

from sst.actions import *
from lettuce import *

@before.each_scenario
def setup_browser(scenario):
 #start(browser_type='Chrome')
 pass

@after.each_scenario
def teardown_browser(scenario):
 close_window()

@step('I am at (.*)')
def i_am_at(step, url):
    go_to(url)

@step('I should see the title (.*)')
def should_see_the_title(step, title):
    assert_title(title)

Error messages:

This has been fixed on sst trunk but you should be aware that if starting a browser is handled automatically for sst scripts you need to use sst.cases.SSTTestCase as a base class to get access to more advanced features.

I.e. sst.actions.start (commented out in your example) has been removed and sst.actions.close() requires a test object ('_test' is a hint that should not rely on private stuff ;).

Also, when I say 'fixed', the SSTTestCase object will now properly initalized its 'browser' attribute. But you still need to properly use an SSTTestCase object to get a browser properly initialized.

Can you help with this problem?
