pytest_bdd.exceptions.StepDefinitionNotFoundError 在 StepDefinition 中使用 parsers.re 时触发错误。

我使用了以下功能文件

Feature: Login Page

Scenario: Opening Login page and logging in
        Given URL is created
        When User is opening the login page and entering the details
        Then User is logged in

    Scenario: Opening Login page and registering
        Given URL is created
        When User is opening the login page and registering
        Then User is logged in

对于步骤定义，我尝试使用如下所示的parsers.re来重用这些步骤。（场景，给定然后不粘贴以保持细节清晰）。

from pytest_bdd import scenario, given, when, then, parsers
import re

@when(parsers.re(r'User is opening the login page (?P<login_type>[a-zA-Z]+)'), converters = dict(login_type = str))
def login(login_type):
    return logging_in("name", login_type)

但是，我遇到了以下错误。

request = <FixtureRequest for <Function 'login'>>
step = <pytest_bdd.feature.Step object at 0x103ddd128>
scenario = <pytest_bdd.feature.Scenario object at 0x103dcbf98>
encoding = 'utf-8'

    def _find_step_function(request, step, scenario, encoding):
        """Match the step defined by the regular expression pattern.

        :param request: PyTest request object.
        :param step: Step.
        :param scenario: Scenario.

        :return: Function of the step.
        :rtype: function
        """
        name = step.name
        try:
            # Simple case where no parser is used for the step
            return request.getfixturevalue(get_step_fixture_name(name, step.type, encoding))
        except pytest_fixtures.FixtureLookupError:
            try:
                # Could not find a fixture with the same name, let's see if there is a parser involved
                name = find_argumented_step_fixture_name(name, step.type, request._fixturemanager, request)
                if name:
                    return request.getfixturevalue(name)
                raise
            except pytest_fixtures.FixtureLookupError:

解析器与 re 一起使用的方式是否有问题导致错误？
