测试与水豚和rspec的破坏行动

Question

我在capybara和rspec下,这是测试对象的destroy链接的最佳方法吗？我必须点击此链接

<a href="/categories/1" data-confirm="Are you sure?" data-method="delete" rel="nofollow">Destroy</a>

但是我无法选择它:

it "should destroy a category" do
  visit categories_path
  find(:xpath, '//link[@href="/categories/1"]').click
  # how to handle javascript pop up for confirmation?
end

任何提示？谢谢!

Answer 1

expect { click_link 'Destroy' }.to change(Category, :count).by(-1)
