ruby-on-rails - Rake テスト:ユニットが status(1) で失敗する

Question

Rails を使用したアジャイル Web 開発に取り組んでいますが、実行中に問題が発生しましたrake test:units。

これを Windows 7 で実行していますが、インストールに問題があるのか、それともテストで何かを詰め込んでいるのかわかりません。

完全なトレースは次のとおりです。

Tasks: TOP => test:units

編集：テストは次のようになります。追加require test/unitしても問題は解決しませんでした。

「test_helper」が必要

class ProductTest < ActiveSupport::TestCase
  product = Product.new
  assert product.invalid?
  assert product.errors[:title].any?
  assert product.errors[:description].any?
  assert product.errors[:price].any?
  assert product.errors[:image_url].any?
end

あなたのテストは間違っています：例えば、実際のテストの中にアサーションを入れなければなりません

require 'test_helper'

class ProductTest < ActiveSupport::TestCase
  test "products should do bar" do
    assert ...
  end

  test "product should do foo" do
    ...
  end
end
