当我 运行 测试“ rspec item_container_spec.rb ”时,我会在控制台中收到警告
When I run the test “ rspec item_container_spec.rb ”In the console, I'll get a warning
it 'add items into the container' do
item1 = Item.new('kettle', price: 200)
item2 = Item.new('kettle', price: 300)
@box.add_item(item1)
@box.add_item(item2)
@box.items.should have(2).items
end
这支球队可能会失误? “@box.items.should 有 (2).items”。
在控制台中,我会收到警告
**E:\work\storeapp\spec>rspec item_container_spec.rb
F
Failures:
1) ItemContainer add items into the container
Failure/Error: @box.items.should have(2).items
NoMethodError:

1 example, 1 failure
Failed examples:

我哪里错了?
我打赌你已经安装了rspec 3.0.
have
匹配器系列在 RSpec 2.99 中被弃用,并已从 RSpec 3.0 移至单独的 rspec-collection_matchers gem。
