这是我在 Rails 测试的第一天，我有一个工作项目，但根本没有添加任何测试。首先，我想rake看看一切是否正常（为了一个好的开始），但是......

    [37/38] UsermailerTest#test_notifyadmin = 0.00 s              
    25) Error:

    Errors running test:functionals! #<RuntimeError: Command failed with status (26): [ruby -I"lib:test" -I"/Users/linus/.rvm/gems/ruby-2.0.0-p247/gems/rake-10.1.0/lib" "/Users/linus/.rvm/gems/ruby-2.0.0-p247/gems/rake-10.1.0/lib/rake/rake_test_loader.rb" "test/functional/**/*_test.rb" ]>

我完全不知道这里出了什么问题（对我来说是新领域），它来自哪里或如何解决它，所以我真的希望有人能提供帮助。如果这很重要，我会设计用于用户管理。

注意：上面的这个错误不是唯一的，其中有“很多”，所有开始几乎相同，所以我想我只是为了清楚起见添加一个。

[37/38] UsermailerTest#test_notifyadmin = 0.00 s              
        25) Error:
        test_notifyadmin(UsermailerTest):
        NameError: uninitialized constant UsermailerTest::Usermailer

等等...

更新

这是来自 test/functional/usermailer_test.rb 的代码

需要'test_helper'

class UsermailerTest < ActionMailer::TestCase
  test "notifyadmin" do
    mail = Usermailer.notifyadmin
    assert_equal "Notifyadmin", mail.subject
    assert_equal ["to@example.org"], mail.to
    assert_equal ["from@example.com"], mail.from
    assert_match "Hi", mail.body.encoded
  end

end

事实证明，一些测试控制器有 2 个版本。有些被命名为复数，有些被命名为单数。单数命名的控制器会导致错误消息，因为它们不是最新的我对 mvc 控制器所做的最后更改。此外，我将一些控制器（如 Usermailer）重命名为 UserMailer，导致无法找到它们。
