アプリケーションのソースコードは以下の通りです。行アサートでエラーが発生しました。

require 'test_helper'

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?
  # test "the truth" do
  #   assert true
  # end
end

次のようにする必要があります。

class ProductTest < ActiveSupport::TestCase

  test "product attributes must not be empty" do
    product = Product.new
    assert product.invalid?
    assert product.errors[:title].any?
    assert product.errors[:description].any?
    assert product.errors[:image_url].any?
    assert product.errors[:price].any?
  end
end

このコマンドには外部クラスを使用します

include Test::Unit::Assertions

require 'rubygems'
require 'selenium-webdriver'
gem "test-unit"
require 'test/unit'

include Test::Unit::Assertions

class Transaction

         def createassert()   

          assert(driver.find_element(:id, "amount").text.include?("$244.00")," amount not valid")

         end

class Evaluate

tra=Transaction.new
tra.createassert()

end
