Question

以下是我的RSpec代码段：

describe UsersController do
  def mock_authentication_token(user, token_string)
    ...
    ...
  end

  def create_data
    @date_format = '%Y-%m-%d %H:%M:%S'
    today = Time.now
    @today_str = today.strftime(@date_format)
    ...
    ..
    ..
  end

  before do
    @current_user = Factory(:client)
    authtoken_str = "client auth token string"
    mock_authentication_token(@current_user, authtoken_str)
  end

  context "action: index" do
    before do
      create_data
      @params = @params.merge(limit: 5)
    end

    it "should return the more link with date set to 1 second ahead of #{@today_str}" do
      get :index, @params

      body = JSON.parse response.body

      ...
      ...
      ...
    end
end

此示例 it“应返回更多链接，日期设置为＃{@ today_str}之前的1秒”执行失败时它不会打印实例变量@today_str设置的值失败的示例说明中的辅助方法 create_data 。

它只是打印：应该返回更多链接，日期设置为之前的1秒

似乎它方法不允许字符串插值。这是真的吗？如果是，我如何实现所需的行为。

谢谢， Jignesh

Rspec在每个@块之后重置类实例it变量。

例如：

describe 'it blocks' do

  before :all
    @reset = 0
    @@global = 'will break tests'
  end

  it 'should increment' do
    @reset += 1
  end

  it "shouldn't forget it, either" do
    # but it does
    @reset.should eql 0
  end

  it 'does remember class-level variables, though' do
    @@global += ' for sure'
  end

  it 'can be demonstrated via' do
    @@global.split(' ').should > 3
  end

  # this is not the same @reset as what's in `before :all`.
  this_is_blank = @reset
  it "won't interpolate #{this_is_blank} because it's an instance level variable" do
    true.should be true
  end

  local = 'might as well hard code them into your descriptions at this point'
  it "Doesn't matter anymore because you #{local}" do
    true.should eql true
  end

  it "won't get here because class-level variables #{@@global}" do
    (2 + 2).should eql 5
  end

end

看起来你必须更一般地命名你的规范测试。无论如何，我有。

Rails / RSpec“it”方法描述和字符串插值
