Rails/RSpec-为Flash通知编写RSpec测试

下面是我的助手显示flash通知的方法

我想写Rspec测试，所以我怎么写呢

请帮帮我

def flash_type_to_alert(type)
    case type
    when :notice
      return :success
    when :info
      return :info
    when :alert
      return :warning
    when :error
      return :danger
    else
      return type
    end
end

谢谢，请提前

首先，我将改进您的助手删除所有

return

语句并删除案例

info

def flash_type_to_alert(type)
  case type
  when :notice
    :success
  when :alert
    :warning
  when :error
    :danger
  else
    type
  end
end

您需要的测试如下：

describe "flash_type_to_alert(type)" do
  it "defines the success class when flash notice is set" do
    expect(helper.flash_type_to_alert(:notice)).to eq(:success)
  end
  it "defines the warning class when flash alert is set" do
    expect(helper.flash_type_to_alert(:alert)).to eq(:warning)
  end
  it "defines the danger class when flash error is set" do
    expect(helper.flash_type_to_alert(:error)).to eq(:danger)
  end
  it "defines the given class when any other flash is set" do
    expect(helper.flash_type_to_alert(:info)).to eq(:info)
  end
end
