Cucumber :: ArityMismatchError之后的错误 [英] Cucumber::ArityMismatchError error after Transform
本文介绍了Cucumber :: ArityMismatchError之后的错误的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我的步骤定义
Transform /^user "([^"]*)"$/ do | email |
Person.find_by_email(email)
end
Given /^login as (user "([^"]*)")$/ do | user |
login_as email
end
我的功能
login as user "ca@example.org"
我收到此错误
And user "ca@example.org" has security role "contact" # features/step_definitions/security_role_steps.rb:14
And login as user "ca@example.org" # features/step_definitions/security_role_steps.rb:10
Your block takes 1 argument, but the Regexp matched 2 arguments. (Cucumber::ArityMismatchError)
features/step_definitions/security_role_steps.rb:10:in `/^login as (user "([^"]*)")$/'
./vendor/plugins/shway_skeletons/lib/shway_skeletons.rb:94:in `send':in `/^login as (user "([^"]*)")$/'
features/manage_security_roles.feature:14:in `And login as user "ca@example.org"'
我无法弄清楚任何人
推荐答案
这是因为（ user （[^] *）正在捕获某个群组，则实际的电子邮件正在捕获另一个群组，以阻止该群组，使用非捕获群组或完全不进行群组。 / p>
This is because the parentheses around ( user "([^"]*)" ) are capturing a group, then the actual email is capturing another one. to prevent that, use a non-capturing group, or don't group at all.
Given /^login as user "([^"]*)"$/ do | user |
login_as email
end
或
Given /^login as (?:user "([^"]*)")$/ do | user |
login_as email
end
