我正在使用rails进行敏捷Web开发，并且在运行rake test:units时遇到了麻烦。
我在Windows 7上运行它，我无法判断我的安装是否存在问题，或者我是否填充了测试内容。
以下是完整的跟踪：

Tasks: TOP => test:units
编辑：测试看起来像这样。添加require test/unit并未解决问题。
要求'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?
end
答案 0 :(得分：0)
您的测试是错误的：您必须将断言置于实际测试中，例如
require 'test_helper'
class ProductTest < ActiveSupport::TestCase
test "products should do bar" do
assert ...
end
test "product should do foo" do
...
end
end
