Question

我正在尝试测试我的用户模型（使用devise gem）。我正在rails4 gem的devise分支上运行。我正在尝试编写最小密码长度的测试。

在我user_spec.rb中，我写过：

require 'spec_helper'

describe User do
  before { @user = User.new(full_name: "Example User", email: "user@example.com", password: "foobar", password_confirmation: "foobar") }

  subject { @user }

  it { should respond_to(:full_name) }
  it { should respond_to(:email) }
  it { should respond_to(:password) }
  it { should respond_to(:password_confirmation) }
  # it { should ensure_length_of(:password).is_at_least(8) }

  it { should be_valid }

  describe 'when full name is not present' do
    before { @user.full_name = " " }
    it { should_not be_valid }
  end

  describe 'when email is not present' do
    before { @user.email = " " }
    it { should_not be_valid }
  end

  describe 'when password is not present' do
    before {@user.password = " "}
    it { should_not be_valid }
  end

  describe 'when password is too short' do
    it { should ensure_length_of(:password).is_at_least(8) }
    it { should_not be_valid }
  end
end

但是，在运行rspec spec/：

时，我仍然遇到此失败/错误

Failure/Error: it { should be_valid }
expected #<User id: nil, email: "user@example.com", encrypted_password:
"$2a$04$/Ifwb1dmfzG6xtBS/amRfOrTTopd8P6JSV48L0G/SWSh...",

but got errors: Password is too short (minimum is 8 characters)

Answer 1

在我看来，你的spec文件工作得很好。

你的it { should be_valid }测试在第14行失败。这是失败的，因为你的密码为“foobar”，只有6个字符长，因而使用户无效。

尝试更改

before do  
  @user = User.new(
    full_name: "Example User", 
    email: "user@example.com", 
    password: "foobar", 
    password_confirmation: "foobar")
end

为：

before do  
  @user = User.new(
    full_name: "Example User", 
    email: "user@example.com", 
    password: "foobar123", 
    password_confirmation: "foobar123")
end

Answer 2

您为测试创建的用户没有有效密码。因此，您的测试实际上保证了预期的行为。

将您的测试用户密码更改为：“长测试密码”，它应该可以正常工作。

祝你好运

使用Devise使用RSpec测试密码长度
