水豚 Rails 5.1 中 assert_text 的类型错误

Question

我是 Rails 5.1，正在使用默认系统测试进行测试

我在 class RetreatTest 中有以下代码：

test "Create a new Retreat" do
  visit retreats_url

  click_on 'Create a new Retreat'

  fill_in "Title", with: "Retreat Title"
  fill_in "Tagline", with: "Retreat tagline"
  select('Individual', from: 'Type')

  fill_in "Description", with: "Retreat Description"
  attach_file('Image', Rails.root.join('test', 'images', 'test-1.jpg'))

  click_on "Submit"

  assert_text("Retreat was successfully saved.")
end

我不明白为什么我总是收到这个错误：

Error:
RetreatsTest#test_Create_a_new_Retreat:
TypeError: exception class/object expected
test/system/retreats_test.rb:36:in `block in <class:RetreatsTest>'

如果我写 assert find('.alert').has_content?('Retreat was successfully saved.') 而不是 assert_text 我所有的测试都会通过。

有人可以帮我解决这个问题吗？

编辑 1：在运行使用回溯选项的测试中，我得到以下信息：

Error:
  RetreatsTest#test_Create_a_new_Retreat:
  TypeError: exception class/object expected

升级到最新的 Capybara (2.14.4) 您目前使用的是 2.14.2，2.14.3 中有一个针对迷你测试断言的修复程序，应该修复不正确的错误，并拥有它 return 正确的错误（找不到文本）
