1. Converters

Converters are used by the step_definition functions so that the functions can accept other argument types than strings.

The converters can turn the arguments into “float”, “int” and “str” types, for example:

Float Type.

@when(parsers.parse('the user searches for "{text}"'), converters={"text": float})
def search_phrase(browser, text):

Int Type.

@when(parsers.parse('the user searches for "{text}"'), converters={"text": int})
def search_phrase(browser, text):

1.1 Implementation

“web.feature”:

    @basic-search
    Scenario: Basic DuckDuckGo Result Title
        When the user searches for "123"
        Then results title contains "123"

“test_web_steps.py”:

@when(parsers.parse('the user searches for "{text}"'), converters={"text": str})
def search_phrase(browser, text):
    DuckDuckGoSearchPage(browser).search(text)

2. Running Tests

2.1 Running tests by Tag

Run the command below to test only the scenario where the converter was implemented.

pipenv run python -m pytest -k "basic-search and not independence-search"
