Question

我正在学习Michael Hartl的教程。我使用RSPEC来运行测试。到目前为止一切都那么好，但似乎我已经碰到了以下例子。

这是失败的测试（它应该通过）：

describe "authenticate method" do
  it "should return the user on email/password match" do
    matching_user = User.authenticate(@attr[:email], @attr[:password])
    matching_user.should == @user
  end
end

以防万一。 @user定义为：

before(:each) do
  @user = User.create!(@attr)
end

@attr定义为：

before(:each) do        
  @attr = {
          :name => "Example user", 
          :email => "user@example.com",
          :password => "foobar",
          :password_confirmation => "foobar"
        }
end

user.rb中的条目

before_save :encrypt_password

def has_password?(submitted_password)
    encrypted_password == encrypt(submitted_password)
end

def self.authenticate(email, submitted_password)
    user = find_by_email(email)
    return nil  if user.nil?
    return user if user.has_password?(submitted_password)
end

private

def encrypt_password 
      self.salt = make_salt unless has_password?(password)
      self.encrypted_password = encrypt(password) 
end

def encrypt(string)
      secure_hash("#{salt}--#{string}")
end

def make_salt
      secure_hash("#{Time.now.utc}--#{password}")
end

def secure_hash(string)
      Digest::SHA2.hexdigest(string)
end

测试失败时显示错误消息

我会很感激任何指针，非常感谢。

如果matching_user为零，那么您可能需要在puts email中添加一些puts user.inspect和self.authenticate语句来进行调试。

似乎无法通过电子邮件找到用户，或者由于某种原因，您的密码在验证方法中不正确。

在ruby教程中失败测试（Michael Hartl）
