ruby-on-rails - 设计/ capybara 模糊匹配

Question

我正在使用 devise 创建一个注册向导，
但 capybara (2.0.2)提高

Feature: Signing up
    In order to be attributed for my work
    As a user
    I want to be able to sign u

Scenario: Signing up
    Given I am on the homepage
    When I follow "Sign up"
    And I fill in "Email" with "user@ticketee.com"
    And I fill in "Password" with "password"
    Ambiguous match, found 2 elements matching field "Password" (Capybara::Ambiguous)
./features/step_definitions/web_steps.rb:10:in `/^(?:|I )fill in "([^"]*)" with "([^"]*)"$/'
features/signing_up.feature:10:in `And I fill in "Password" with "password"'
    And I fill in "Password confirmation" with "password"
    And I press "Sign up"
    Then I should see "You have signed up successfully."

步骤定义是

When /^(?:|I )fill in "([^"]*)" with "([^"]*)"$/ do |field, value|
  fill_in(field, :with => value)
end

Answer 1

在版本 2.0 Capybara 中 find方法引发 Capybara::Ambiguous当找到多个与指定定位器匹配的元素时出现异常。 Capybara 不想为您做出模棱两可的选择。

正确的解决方案是使用另一个定位器(例如 find('#id').set('password') 或 fill_in('field_name', with: 'password' )
