Rails Minitest with Capybara，如何使 assert_select "button"、"label" 正常工作？

Question

在（未启用水豚的）IntegrationTest 中，此断言有效：

assert_select "button", "Update"

页面包含：

... <button name="button" type="submit" class="btn btn-primary">Update Account</button> ...

我需要 Capybara 进行一些 IntegrationTest 测试。

当包含 Capybara::Minitest::Assertions 时，如何执行相同的断言（例如，简单地断言有一个带有文本更新的按钮）？

我将水豚添加到 test_helper.rb 中，如下所示；现在，同样的断言现在抛出这个错误：

TypeError: no implicit conversion of String into Hash

如果我将断言的格式更改为：

assert_select "button", text: "Update Account"

它现在抛出这个失败：

expected to find select box "button" that is not disabled but there were no matches

如果我将断言的格式更改为：

assert_selector "button", text: "Update Account"

它现在抛出这个失败：

expected to find css "button" but there were no matches

# test_helper.rb
require 'capybara/rails'
require 'capybara/minitest'

class ActionDispatch::IntegrationTest
  include Devise::Test::IntegrationHelpers
  include FactoryBot::Syntax::Methods
  # Make the Capybara DSL available in all integration tests
  include Capybara::DSL
  include Capybara::Minitest::Assertions  #### THIS LINE changes minitest assert_select #####

  # Reset sessions and driver between tests
  teardown do
    Capybara.reset_sessions!
    Capybara.use_default_driver
  end
end

你想要

assert_selector :button, "Update Account"

但是您还需要使用 Capybara 方法进行会话控制，visit，等等 -- Capybara 不使用来自集成测试的 get、post 等响应.
