BDD for pytest
Project description
Implements a subset of Gherkin language for the behavior-driven development and automated testing. Benefits from the pytest and its dependency injection pattern for the true just enough specifications and maximal reusability of the BDD definitions.
Example
publish_article.feature:
Scenario: Publishing the article
Given I'm an author user
And I have an article
When I go to the article page
And I press the publish button
Then I should not see the error message
And the article should be published # Note: will query the databasetest_publish_article.py:
from pytest_bdd import scenario, given, when, then
test_publish = scenario('publish_article.feature', 'Publishing the article')
@given('I have an article')
def article(author):
return create_test_article(author=author)
@when('I go to the article page')
def go_to_article(article, browser):
browser.visit(urljoin(browser.url, '/manage/articles/{0}/'.format(article.id)))
@when('I press the publish button')
def publish_article(browser):
browser.find_by_css('button[name=publish]').first.click()
@then('I should not see the error message')
def no_error_message(browser):
with pytest.raises(ElementDoesNotExist):
browser.find_by_css('.message.error').first
@then('And the article should be published')
def article_is_published(article):
article.refresh() # Refresh the object in the SQLAlchemy session
assert article.is_publishedInstallation
